Laptop crashed


Really need more information, but my guess is dirty fan. If fan is blocked by dust, it may make noise and may run at high speed all the time because the CPU is overheating. If CPU gets hot enough, the laptop will shut itself down without warning. If dust is the problem, get some canned air. Before blowing into the air vents, try to spot where the CPU fan is and gently insert a toothpick to block the fan and prevent it from turning. A long blast of compressed air can spin the fan too fast and burn out its delicate bearings. Blow air from underneath and also from the side vent until air blows clear. In some bad cases of dust, the bottom or top cover must be removed to get it all out.

Fan on Dell M5030 Starts on startup and then shuts down but computer continues to boot


Lots of fans are variable speed. Meaning they spin faster when the computer is hot and slow down when not. It's most likely spinning down. If the fan was bad the computer will either shutdown or generate an error during BIOS and halt the boot process.

Screen not displaying. and fun starts and stops, remains stand by when restarted the fun runs and stops stand by.


hello there,

I got the same problem but it came gradually...

In fact for a full month when I first boot the computer, the fans runs, no extra beeps, the light blinked correctly but no bios at the screeen. I remarked also that the fans run full speed doing a lot of noise. Then I stopped the computer and wait 2 minutes and then it always works correclty at the second boot with the bios screen appearing. Also, the fan calm down after 1 second with less noise. So when I start the computer and hear that the fan calm down with less noise after 1 second, I know that the computer will boot correctly. That happens always at the second try after waiting 2 minutes. But since yesterday, the fans never calm down and the noise still remains high with no Bios at the screen. I'm suspecting the Power Supply...

i hope my i dea can help you.

Loud Noise on laptop when booting


Most likely it is the POST throttling up the fan to 100% during boot up. Then it switches over to ACPI(?) power manangement and Windows manages your fan speed to extend battery life.

Suggestions:
Go to Dell Support Site https://support.dell.com/support/supportrequests/create.aspx?c=us&cs=19&l=en&s=dhs
Download the latest BIOS updates and run it.

If it continues, try a can of compressed air, and breifly blow out any debris from the system fan. Bits of paper and critter-fur can get sucked up into the system.

2 ghz processor running at 220 mhz


Hi,

Have you tried right clicking on the desktop (opening Display Properties), clicking on Screen Saver tab, Clicking the Power button, and setting the power schemes to Home/Office Desk? If its set on laptop it will reduce the processor speed when running on battery. I have noticed that even with it plugged in that some times it will run at half processor speed. Try that out.

Have a great day,

Power cable


If the system is posting and you can access the BIOS, then the ac adapter is probably giving the system enough power. Remove the HDD, see if the Clicking goes away and see if the system will boot to a WIndows XP CD with the HDD removed. (Most clicking issues in a portable are drive related.

If the system will post and boot to a CD with the HDD removed, then most likely the HDD is bad and will need to be replaced.

If the noise and boot problem do not change, then I'd see if the system runs normally with a Dell power adapter next.

Fan makes a lot of noise, then computer suddenly shuts down


Seems to be overheating. When you say the fan makes a lot of noise, do you mean an unusual noise or just that it is on high?

Fan/Overheating issues averatec 3200 series Laptop


Fans on laptops run when the CPU is taxed. The more its taxed the louder it will be due to higher fan speed. The laptop over the years has gotten bloated with programs and stuff that gets in and stays on your hard drive. The more programs running in the backround the more the CPU is taxed. Try uninstalling useless programs first, empty your recycle bin, delete temporary internet files and cookies, run the disk cleanup utility then perform a scan disk and a deframent. Also you may want to add more memory to your system if it needs it. I use crucial's website (crucial.com) to scan the computer and tell me what memory I can use in my machine. Hope this info helps you out.
