I've just been looking at this again and found that both sides of the R15 chips go to ground so I think there is another short. Can any one confirm that the R15 chips seen in the photo should not have both sides going to ground?

Yes, I believed that to be so, thanks for confirming....

Sorry, not sure what you are asking here?...

Also, is there any recommendations on a thermal camera?

Hi all,

Looking for some help on fixing a Acer Predator Triton 300.

When the laptop was given to me it was dead, wouldnt charge and no lights or life at all.

I quickly established that two MOSFETs were shorted and replaced them (the first MOSFET in the charging circuit and then also one of the MOSFETs for the CPU (see attached photo showing the MOSFETs replaced). I now have life in the laptop where the battery light now comes on and it charges the battery. When I press the power button the backlight on the keyboard comes to life (it has a keyboard light program...

Thanks, checked it with a hex editor and saw my serial number in the file and so used ASProgrammer to apply and verify the BIOS you provided. It hasnt made any difference but I wasnt sure what I need to do with the EC file you attached? Can you advise?

Cheers,
Scott...

Thanks, is the file you attached a fixed version of the bios for the laptop? Has my serial number been added to it? I was unsure how to insert the serial number to a new bios file correctly.

Thanks,
Scott...

Hi all,
My name is Scott and I am from the UK!

Hi All,

I am working on this laptop which came to me dead and not charging. I replaced two MOSFETs which now has the laptop charging and will turn on but it get no POST, just a blank screen when power is turned on (both on actual screen and HDMI).

I expect the BIOS is corrupt. I have a CH314A which I am using. Strangely none of the programs can verify the BIOS once its been read. I've attached three dumps I got the chip, the first two were using SiberiaProg and the 3rd one is using ASProgrammer. Hoping that someone can help with creating a working BIOS for the laptop....
