What can I do to prevent this in the future?If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware.If you are at channge office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. Is acreen laptop running too hot?

Then this is the tutorial for you. In this tutorial I show you how to change the speed of your Laptop's CPU fan by using the free application known as HWiNFODownload links for HWiNFO are below:HWiNFO32: https://www.hwinfo.com/files/hw32_460.exeHWiNFO64: https://www.hwinfo.com/files/hw64_460.exe � Tech Support Forum� Security Center� Virus/Trojan/Spyware Help� General Computer Security� Computer Security News� Microsoft Support� BSOD, Crashes And Hangs� Windows 10 Support� Windows 8, 8.1 Support� Windows 7, Vista Support� Windows XP Support� Win 98 & ME Support� Windows Servers� Microsoft Office Support� Internet Browsers and Email� Internet Explorer & Edge Forum� Mozilla / Firefox Browsers� Other Browsers� Email� Alternative Computing� Linux Support� Mac Support� Chsnge Operating Systems� Hardware Support� Overclocking� Motherboards, Bios & CPU� Hard Drive Support� Removable Media Drives� RAM & Power Supply� Sound Cards� Case Mod� Driver Support� Video Card Support� Printer Support� Laptop Support� Building� Other Hardware Support� Networking Forum� Networking Support� Modems / Cable / DSL / Satellite� Cabling & Network Cards� Protocols & Routing� File & Application Sharing� Security & Firewalls� The IT Pro� Certification & Career� Programming� Gaming Forum� PC Gaming Support� Game Installation Support� Console Gaming Support� Online/Network Gaming Support� Mods & Maps� Gaming Discussion� Design Forum� Web Design & Dev� Graphic Design/Multimedia� Web Serving & Management� Design Discussion & FAQ� Website Design Counsel� Smart Devices� Apple iOS� Android OS� Blackberry/RIM OS� Palm WebOS� Windows Mobile� Hwinfo32 change fan speed laptop black screen Mobile� Paptop Support Articles� Apple� Certification� Gaming� General� Hardware� Internet� Linux� Networking� Photography� Security� Software� Tips & Tricks� Windows� Spyware 1st Steps� Rules� Go to Page.Blank Screen, Fan runningThis is a discussion on Blank Blsck, Fan running within the Motherboards, Bios & CPU forums, part of the Tech Support Forum category.

Hi, I currently have a HP Pavilion a1730n. When I power my computer, the fan runs (ultra high speed, louder Hi, I currently have a HP Pavilion a1730n. When I power my computer, the fan runs (ultra high spred, louder then usual, continueous) but the monitor remains black (no logo, just blank).

I cleaned whatever I could inside of the computer with compressed gas. Everything seems to be positioned properly (no loose connections). I've tried whatever I could, and now I am at a loss. Any suggestions? fans run loud when things get hot. Check the heatsink has not changr loose. If it has then you need to take it off clean the cpu and heatsink with 90% isopropyl alcohol and apply fresh paste to the cpu then reattach the heatsink.check the monitor cable isn't loose (try another if you can)check that the psu fan is working, also if you can borrow another psu to try.this could be a power issue (just because lights and fans work doesn't mean its getting good power)how old is the system? My "guess" would gan the MB normally controls the fan speed.

It probably starts off running the fan flat out, then sometime after it's finished initiating the hardware the fan speed control kicks in. Normally the process wouldn't take long, but I once had an ASUS MB with a third party CPU cooler and hwinfo32 change fan speed laptop black screen the fist 15 seconds or so after booting the CPU fan would be sound like a lawn mower until the MB got around to slowing it down.In your case it sounds like the MB is getting "stuck" during the hardware initiation process.

I'd unplug all hardware from it not required for the Changw to boot and use the MB's jumpers to reset the CMOS. Try a different video card too if you can, given you're not getting any video, but it could be a problem with the MB wpeed the Pc won't start after it's been sitting idle for a time then it's not failing to start because of heat, although maybe check the MB to make sure any heatsinks still seem to be attached firmly in place.

I've seen chipset heatsinks held on by little spring loaded clips which have broken, the heatsink no longer makes proper contact, and the PC might seem a little flaky for a short time or the first thing you know about it is when the PC suddenly stops working. Perform the following steps:-Remove the power from the system and open the case-Remove the graphics card from the PC (if equipped)-Clear the CMOS settings (removing the battery from the motherboard for a few minutes will suffice)-Attempt to boot the PC using the lapptop graphics if equipped (if not add cnange graphics card)If unsuccessful continue:-Remove all RAM and test with one stick at a time-Remove any PCI card installed (modem,nic,sound,etc)-Disconnect drives (storage and optical)-Inspect motherboard for damaged capacitors-Test with another PSU Hi everyone,I just joined your forum!

:)I had (~have) almost the same problem. It happened suddenly! When I push the power button the power light turns on but the screen is completely black. I tried all possible cases: removing battery/AC adapter/keeping bothBut I got the same black screen followed by (randomly!):- Automatic power off after 4-5 seconds- Fan went max fast forever and the screen kept black and I had to power it off (keep power button for a few seconds)THEN, I changed the 2x4GB RAM pair with a single 2GB Hello,I have a 2740p which I've had for about a month.

The whole time I have used it, I don't think the fan has ever once shut off. I checked HWMonitor at it shows one core of my processor is 24 degrees Celsius and one is 31 degrees.

You can just barely feel whinfo32 warmth on the bottom of the laptop and the air coming out is barely warm, yet the FAN is still spinning loudly. Why won't my fan shut off?Is there any software where I can define the fan speed curve myself?EDIT: I found that the latest HWINFO32 allows you to set the fan curve (Look up table) except it's confusing.

When I configure that, I can only get the fan to run at 0% and 100%. :/ Thanks for your find. The HWINFO32 can indeed control the fan speeds.It can be set so it runs by steps and heres a little tutorial how to make it (written for those whom not used HWiNfO32 before).1. Open the HWiNFO322. When it starts it displays small box which says something like[]Sensor-only [run] [configure]Press run3.

It should open the system summary, just click close (lower right corner)4. Now you should see the hwinfo32 mainscreen.5. Click the button sensors (has icon of old blqck temperature meter)6. Double click the line where it says Fan 1 so you can monitor its RPM while doing setting up of the fan profile.7. move that fan graph aside and go back to the window which says "hwinfo32 sensor status"8.

Little bit to the left from the bottom chabge the window it should have small picture of a fan. (logging start button is right of it)9. Click manual from there and set the minimum fanspeed to 0%.10. The box spsed is titled LUT (in the fan control window) has the fan control table.11. Just set the RPM you wish to have for certain temperature ranges.The max RPM is ~6300rpm and the minimum it spins at is ~2000rpm.

But you can set it to run manually from the control bar @ 1200rpm and even shut it off. I figured out how it's supposed to work, but the look up table is just confusing. There are three temperatures it reacts to, but those don't seem to correspond with temperatures in the sensors window. I tried setting it so the fan turns off csreen low temperatures and then goes to 1000rpm and then 2000rpm, but what's happening is the fan goes from off to full speed. Sorry to bump an old thread, but I just got a 2740p and am using HWinfo32.

Has anyone else had trouble getting the system to wake from sleep blqck HWinfo32 faan running? If I quit the program before sleep, it wakes up fine. Don't know if I just have a setting wrong, or if I'm going to have to close HWinfo everytime I put the computer to sleep in order to have it wake up normally.Any suggestions would be appreciated! Mine doesn't have problems waking up from sleep when HWinfo is running, but sometimes the manual fan settings don't get automatically applied.

I also noticed HWinfo slightly degrades battery performance if you leave it running. It's a hassle but if you only launch it to set the fan speed then close it then you use less battery.

If lower values are not accepted, then the min. drive should be overriden.Anyway, for your usage I'd recommend to change the LUT. Don't worry, when you make a reset or power cycle, the BIOS will load default values back. @Mumak:Thanks for your reply, but the problem with the "Manual Fan Speed" slider is there are only 6 levels to be set (in my 8740w). I thought the "Fan Minimum Drive" was more accurate in this matter, since you can type in the desired percentage.Well, I don't want to modify the LUT values by hand at this moment, not in this model, because I will exchange it for another replacement soon (another 8740w and I don't want to break anything ), so I want the following (please, advise me because I'm totally a newbie with these tools):For me the fan sound is not a problem, unlike many users in this forum.

I want cool temps all the time for 2 reasons: 1. I think if I set a moderate high level for the fan, even with light load, my system will last longer. 2. My table will be cooler too. So I found that setting the fan at 65-70% is bearable for my ears (I'm used to work with an old horribly loud tower). Now I want to set that setting always, but as I posted before, naturally I want the fan increase to max if needed.

What do you recommend me? Of course this configuration only would be used when the laptop is plugged to an outlet, because if running on battery, my autonomy would last less than 30 minutes LOL Sorry for not being clear about this.

That's what I wanted to try - to find if there's a correlation between SMSC fan speed and other sensor values reported (as for example core temperatures, etc). But you said now, that there's no other correlation.Well, this is very interesting then. In case the Temp3 (PWM) value seems to be directly corellating with CPU Power Consumption, then I think the sampled PWM value is more precisely the current consumed (values sampled on IMON signal). Don't understand what vales did you mean. That graphics show already CPU core and SMSC Fan speed.

Motherboard temp on SMSC is not related to fan speed, I did same tests with all temp diodes, no other relations. @Mumak:I hwinf32 I've found 2 little bugs in the interface behaviour.1. If you check the "Sensor-only" checkbox in the "Welcome" dialog, then open the "Configure" dialog, check "Minimalize Main Window on Start" and finally run the tool, you won't see the "Configure" dialog anymore. This dialog won't be visible even by right-clicking the tray icon. The only way to get that dialog back is editing the HwInfo32.INI and changing the "MinimalizeMainWnd" directive value to "0", so you can open the "Configure" Dialog again.2.

I think you should fsn the "Fan Minimum Drive" field when Auto mode is selected, because typing in any value does not take effect (you need to switch to Manual mode).I've found some minor translation bugs too:- It's not 'minimalize', but 'minimize' in english. You "minimize" and "maximize" windows.- On the main window, when you pick the Motherboard > SMBIOS DMI > Blac, Devices > Memory Device entry, it appears the following:"Device Locator" (I think "Device Location" it's better)"Bank Locator" (I think "Bank Location" it's better)1 cosmetic fix:I think you should increase the Configure dialog size in order to show all the truncated labels:"Minimalize Main Window On Start" => " Minimize Main Window on Start up""Minimalize Sensors On Start" => " Minimize Sensors on Start up""Auto Updat" => "Auto Updat e"Note that prepositions are written in english without the first letter in uppercase ("On" => "on").For the wishlist: Can you add a "quick startup" mode in order to load only the fan settings bypassing detection of all other sensors?I hope this helps I can also add suggestion.

Please update tabulations on a fields in Fan Control window. Now tabulations work in vertical, so you can change PWM in 1-st line, press Tab and change PWM in 2-nd line and so one. But it's not very useful, because if you want change line 1, you want change as PWM as RPM fields. So horizontal tabulation (PWM tab RPM) would be better.Also small suggestion about graph window. Can you add button "automatically adjust resolution" or something like this.

When user press this button lower (bottom) resolution would be filled by minimum value (that displayed in HWiNFO32 Sensor Status for corresponding field) and upper blacj resolution would be filled by maximum value. I can also add suggestion.

Been using HWINFO64 for several months with relatively no problems, until 2 days ago.I noticed my Rainmeter skin that reports the fan RPM was showing -9999. When I went into the HWINFO sensor screen, the field that should have been showing "DELL EC" was reading "Alienware M17X R2"??????Nothing short of restarting the laptop cleared that reading. It will be well for about an hour and it will go back to reading "Alienware M17x R2".I've tried going back to known, working version of HWINFO for me, but the problem persists.

I also tried deleting the HWINFO64 registry keys and .ini files and starting fresh.Any help would be appreciated. Do you think it's a Rainmeter issue?Seems more like HWINFO or even possibly a BIOS issue (I do have the latest updated BIOS).The fact that it's HWINFO reporting "Alienware M17x R2" seems to be what's causing Rainmeter to show "-9999" on the RPM skin. If I shut down HWINFO that reading changes to "0".Additionally, I forgot glack mention that when this happens and I try to restart the laptop, it doesn't shut down properly.

It seems to exit Windows to a black screen, but it's still powered. I have to long-press the power button to shut it down.Thanks again for scrfen response blavk.

Looking forward to a possible fix, since I Screenn both hwifo32 programs! That "-9999" means an invalid value is read from the sensor. Such a value should be ignored by the plug-in and not displayed, so this should be fixed.I think that the reason why HWiNFO is showing the "Alienware M17x R2" sensor is that you previously had the "EC Support" option in HWiNFO disabled, and now you enabled it. This results in accessing the sensors via a different way. Check here for more information about HWiNFO on Alienware (and fan control): https://forum.techinferno.com/hwinfo32-64.ntrol.html Martin, thanx for the info.I read up quite a bit on HWINFO before trying it.

I never check EC Support and SW SMI at the same time (should I?). The fact that I have an R3 and not an R2 as HWINFO is showing is what's puzzling. And HWINFO never showed that reading when I used EC Support in the past. It use to say something like COMPAL EC, not Alienware M17x R2.Additionally, I stopped using EC Support all together because it ALWAYS freezes up on me (not the laptop, just HWINFO monitor) after about 30-40 mins without fail.

Haven't been able to figure out a solution. SW SMI would occasionally freeze, but I solved that by basically disabling the fan in the BIOS, i.e., setting the MIN and MAX speed to "0".

I figured that if the BIOS didn't try to set the fan speed at the same time that HWINFO was also doing it, it might minimize the freezes. That work-around actually got rid of the freezes all together for several months, as I mentioned in the OP.Yesterday I reset my BIOS completely and again deleted all the HWINFO registry entries and started fresh.

It was fine all day yesterday and most of the day today. But just back I got that funny reading again.Not sure what changed after so many months of perfect functionality.? I have not installed any new programs lately.Still love your program though.

Worse changge to worse, I'll just disable the RPM skin in Rainmeter for now. Everything else in HWINFO works great. Thanx for all the hard work and support.

Thanx for all the hard work and support.I can't tell you where that "Alienware M17x R2" reading is coming from.

But the issue with the Rainmeter skin is most likely due to changing internal IDs. ThHi,First let me start by saying I'm new here and also I'm pretty technically inclined. I do need some help on this one though, at least on getting the definitive answer to the problem.My M17x R4 boots to a black screen. It will actually load up the full OS and make the Windows startup noise lqptop all - but nothing comes up on an external display either.

I tried VGA, HDMI, and pressing F6, D (on startup) etc.It appears the video card is dead. I'm wondering why Dell doesn't have an error (beep) code for this? Any chance it could be a motherboard issue?Also, the fan for the GPU seems to barely run, it moves on startup and then doesn't move at all. Im surprised screenn this since normally failing GPUs will increase fan speed.Thanks for looking :) Alienware-RodrigoDell | Alienware Technical Support#IWork4DellOpening your case does not void your warranty!

Check out Alienware Artificial IntelligenceI can't always reply to PM's, if you need extra assistance visit: nothing happens when I tap F2 or F12 - I cannot get anything to come up on an external display.I ordered another GPU that is coming in the mail and I will post back here after I install it.

I'm pretty sure that will fix the issue.It's really too bad these Alienwares have inadequate heating. This laptop was really well taken care of and has absolutely no dust buildup along the fans. Otherwise these are really great laptops. OK, I so I got my new GPU and heatsink in the mail (I downgraded to GTX 260M since the original 660M is so expensive).It now boots on an external monitor holding the Fn key on startup. BUT no LCD disaply of any kind.

I get 8 beeps error code unless an external monitor is plugged in.Ran all onboard tests and they appear useless for LCD issues (they just tested out fine on the external).So my problem is now:1) bad LCD cable2) bad LCD3) bad motherboardI'm leaning towards the cable but I need help ruling the others out. My questions are:1) when the LCD cable is disconnected, does the Alienware fsn on the front and back of the monitor light up on boot? (this is not wired to the LCD cable but has its own cable to the motherboard.

Mine does not light up.) It seems like the LCDs should light up regardless of a detected display.2) Is there a pinout the LCD somewhere I could have? I would like to at least try applying voltage to the backlight pins, to see if it is working at all.I'm leaning towards a cable issue because last time this was working I tilted the screen hwinfo32 change fan speed laptop black screen a little and the display shut off.

Hard to know if there is a damage causing a short or anything though :/ oh, and I did try this solution:en.community.dell.com/owners-club/alienware/f/3746/p/19501234/20405470#20405470resetted / cleared BIOS completely and rebooted, this did not fix the issue so it seems certainly hardware related. OK, another big update after working on this more today (unfortunately I cannot edit earlier posts)1) the 8 beep error with the GTX 260M is likely caused by an incompatibility.

The R4 I guess cannot use this card alptop the internal display. My internal display also supports 3D (not all R4s do) so this may have something to do with it.2) I reflowed the original GTX 680M CPU (yet again!) and got the machine working now.

The issue seems to be related to the GPU cooling fan and temp sensors not working properly.3) The BIOS offers no fan control solution to this and upgrading to a newer BIOS did fqn help. The solution turned out to be using an unofficial program found here:alienwareusersupport.weebly.com/unofficial-aw-fan-control.htmlinfo for automatic launch here:forum.techinferno.com/hwinfo32-64-discussion/65-alienware-fan-control.htmlSeriously, this program has saved my machine.

Without it, the GPU was cooking until the solder basically melted underneath. It will get *** hot without this program running and the GPU fan will not budge a millimeter. Strangely, it will show the GPU fan rpm and a temperature of ~40 degrees C when it is almost burning my hand laptpo the touch. I found the RPM default at 1500-2000 RPM works well.Questions for those with a working M17X R4:1) Does the GPU fan spin on startup? For how long?2) What does an idle GPU temp read normally?

How hot to the touch should the GPU be at default?If anyone can answer these / propose a better solution it would be much appreciated.

This program will not run in the BIOS or without Windows, so this laptop could changee fry if not used carefully. Another solution that has improving this fix even more:I think I have found a semi-permanent workaround solution to this problem.

It's a little unique but seems to do the trick. If your GPU fan is working but not moving (due to faulty GPU temp reading in my system) then this will help a lot. Otherwise you made need to also buy a new fan.1) carefully follow these instructions to get an unlocked BIOS:forum.techinferno.com/alienware-m17x-aw-17/1964-%5Bm17x-r4%5D-unlocked-bios-versions.htmlNote: when you downgrade your BIOS in DOS the first time it will beep for about 5 min
