I know it doesn't sound plausible, but this was the case with this laptop. If the BIOS is corrupt, the laptop will not power on at all.

That might be possible. I think the best way is to program BIOS chip out of motherboard directly in the programmer. But the worst thing will be to find proper bin file or working dump from same laptop. I got some dumps but not for this particular model.

Yes, it should be evident by mockingbird's and my first post in this thread.
Both our laptops where completely dead after the BIOS update.

In my case the laptop that is dead has two BIOS chips, so I don't want to try flashing it manually with my programmer, since I think the chips are paired (I read something like that on a Russian forum)
Of course my laptop is a special case...

For your laptops I think you should actually be able to program them in circuit, of course it requires a proper programmer to do it, and the correct BIOS binary file to program the chip with...
If it does not comply you will need to desloder the BIOS chip and program it that way, might be enough to lift a leg or two aswell if you know what you are doing...

In modern laptop motherboards, usually there are two flash chips, one for the embedded controller, (ec, kbc, etc.) and the other one that is the "normal" bios, being the second larger than first. (of course the content is different)

Re: Acer Aspire 5315 - Dead

I was updating the BIOS today and it failed with an error. Computer hung up and would not respond ended up pulling the power. Now I get not LEDs, power cord LED when connected or any action of any type when I push the power button. Completely dead. I unsoldered the CMOS battery no help. Tried shorting the pins at four locations with no help. Will try again with more pressure. Would hate to have to consider a new motherboard for an older laptop. First time I have had a bios problem.

Any further suggestions appreciated.

If bios boot block is not damaged, you could try a usb bios recovery.

Hi mockingbird!
I know this is an old topic, but I have the same problem as you.

BIOS recovery from USB not works - no power lights at all.

First time i bricked a pc (me idiot ).

Just wondering what OS version you guys used when run BIOS update utility?
I'm on Win7 SP1. Suppose XP should be used to flash it.
