ACER NITRO AN517-51 BIOS and EC

[sect-sin]

Hi,

I have an Acer Nitro AN517-51 (EH5VF LA-H501P Rev:1A) with a faulty SIO. I want to replace and rewrite it, and also reflash the BIOS for safety's sake. I have attached dumps for both the BIOS as well as the SIO. Can somebody provide me with a clean, up-to-date BIOS with DMI info transferred as well as a separate, programmable EC extraction?

I thank you very much in advance for your help.

Cheers,

Here's your New BIOS, it's a Virgin BIOS from Acer with your DMI and Windows Key.
Also New EC file is attached.

Serial Number: NHQ5CEV010936013643400.

Thank you very much for the files. After successful programming, the notebook still does not work. It is powering on for a split second with keyboard backlight and fan spin, but shuts down immediately. There are no obvious shorts anywhere, and in pressing the power button, the power sequence goes all the way through VCC_SA, but there is no voltage on the Vcore rails, not even for a millisecond. I need to diagnose this further, and will give feedback if I find out what the problem is.

I am having the same problem now = no Vcore rail, only VCC_SA. Did you find the solution?

Hi,

Unfortunately no. In my case everything points to a damaged PCH. I tried everything to no avail.
