G470 BIOS won't boot; won't enter setup or boot device selection (F2, F12); powers off

2013-03-30, 15:43 PM

 

The initial BIOS screen appears, then eventually powers off. F2 to enter setup or F12 to select boot device also don't work.

 

I did a couple of impatient hard power offs and now behaviour is as described - effectively bricked. Grateful for any and all suggestions!

 

I tried booting off a live CD, but unsurprisingly, that didn't work either. When I select F2 or F12, a message appears saying entering Setup or device selection, but nothing happens, then power off after a few more seconds.

Hi

 

Welcome To Lenovo Community

 

We are really sorry to hear about the issue you are facing,  

Please try disconnecting all cable from the unit , Now press the power button for 30-40 sec then release , perform this action 4 -5 times , now connect AC adaptor  to check  by powering on and booting the system. If system is working fine, try entering the Bios, if you are successful press F9 to load Bios defaults   & press F10 to save and exit

 

 

In case issue remains same please contact local Lenovo support to have system verified

Thanks for posting. I'm afraid that didn't work.As well as mains power, I removed the battery.

 

As far as I can see, there are two possibilities: either this is a BIOS problem, or it is a hardware problem. In the first case, a solution like this might work, but not in te second.
