Re: recover bios lenovo G500 black screen

Hi aryaamehr,

  

During boot-up, if pressing Fn+F2 does allow you to access the BIOS, can you try to:

1. Remove the AC adapter and battery then press the power button for 20secs.

2. Reconnect the AC adapter without putting the battery back in and press the One Key recovery button If a menu appears, choose BIOS Setup

Re: recover bios lenovo G500 black screen

thanks Abdul_Ahad

but there is nothing just a black screen!

 

some friends said the problem is with bios and it should be flashed

i've the bios latest file but its an EXE file and needs windows! so i cant use it

there are some methods to recover the bios but the ptoblem is all of them needs some *.bin , *.wph or a *.rom file

in the  bios file which I downloaded from Lenovo.com i coud find a *.Rom file but I couldn't use it!

Re: recover bios lenovo G500 black screen

I encountered this problem and was able to solve it, hold down FN and F8 keys during boot up (lenovo logo) and proceed to advance recovery option, boot to safe mode, uninstall kb2903939 update. reboot to safe mode again, download DDU uninstaller, follow instructions, remove AMD drivers first, reboot, remove intel HD driver reboot. Finally donwload latest intel hd video driver install it, reboot. Download latest AMD, do the same and enjoy life! The main problem is mix up of intel and amd graphic drivers that are incompatible.

Re: recover bios lenovo G500 black screen

Hello,

I've had exactly the same problem. After disabling the integrated graphics... my g500 wouldnt flash and nothing could be seen on the display.

the sollution was very simple and stupid even. The laptop did exactly what i told him to, he disabled the integrated graphics but the dedicated graphics did not come to back it up because that only happens in 3d applications. so i had a blind mode laptop 

The g500 didnt show anything but was working flawlessly. I noticed this when i plugged in the HDD and i heard it was working a little bit too much for a dead laptop. In fact he was booting into windows... when i plugged in a USB stick i heard the windows sound and i was like **bleep** ?!!

Ok.. that was stupid... so no flashing the bios is the sollution. 

Simply power it on normally using the 1 key recovery( the small button near the power button)

This will invoke the boot options menu

1. press down arrow key and enter (this will select enter bios menu)

2. now press f9 or f8 and enter(this will invoke the shortcut to LOAD BIOS DEFAULTS. you can try F8 + ENTER or F8 + Y + Enter just to be sure you  reset to default)

3. after doing so you must save the bios. Press left arrow key to navigate to the exit menu of bios and press enter to save and exit)

Your g500 should turn off and restart and it should be alive.

this may sound wierd, you should look on google for a pheonix bios screenshot to understand better.

Basicly you must enter bios and load the default setting as if you were blindfolded.

Good Luck , hope it helps you as it did me !!!!
