Black Screen, fan runs for 3 seconds and then turns off.

Black Screen, fan runs for 3 seconds and then turns off. . The fan than turns on again and stops. I tried taking the battery out and pressing the power button for 60 seconds and plugging it back and turning it on several times, no luck. Tried plugging in into an external monitor by changing the window settings fn + f4, no luck. Tried switching the placement of the ram and cleaned the ram, no luck. Trying to find CMOS battery but I think this laptop doesn't have one, the main battery serves at the CMOS battery.

I think I disabled something I wasn't suppose to. When I turned on my laptop after that setting change, the blue screen appeared and then turned on. Since that, there is a black screen.

Please help!

I have the same problem black screen with white light power button on power up and hear the fan. What you are saying is that when the battery dies the laptop won't boot up? Can the computer boot if I remove the battery and just use the charger?

I think you should get a new battery for it once you do charge it turn it on and see what it does. One more thing, if you do get a new battery be sure to only charge it when it is almost dead and DON'T keep it plugged in all the time. Both can ruin the battery.

I changed the battery last year and I don't think that is the concern. The battery was working fine and it still detects the battery.

Hello Patel. It seems you may need to replace your fan. We have a fan replacement guide here that can help you. But before this, can you try booting your computer in "Safe mode" (press F8 repeatedly when you turn on your computer). If you are not able to use "Safe Mode," there could be one of two things happening: The BIOS file is corrupted or your operating system is corrupted.

How can I replace BIOS file if it is corrupted also how can I recover my laptop if my operating system is corrupted. There has to be a way to make that laptop run again.

To fix the bios is a process I will have to look more into but to install/repair the operating system, you can use a Windows 7 or 10 bootable usb drive or cd. Before trying to use a bootable usb drive or windows cd, does your computer have Windows 7 or 10? When you have the black screen, can you enter safe mode or does it stay black?

Sorry for the late reply, but the screen stays black when I press f8. My computer came with Windows 8, but I upgraded it to windows 10.

Ok. I looked over the button configurations and saw that FN+F5 is for the external display. I see that you tried using FN+F4. Did you try using FN+F5 while connected to an external display?
