The new bios file is fine, your damage is not caused by the bios.

You burned a fuse or something else around the connector, flashing the bios won`t solve it.

Many thanks.

Here is the latest and an earlier version, you can choose the one you like.
Both have your DMI transferred.

Thanks, looks like both files are 0B? Not able to download.

[Vesko356]

Try again, both download links are fine, please refresh the page.

Sorry for late reply I had to order new programmer as it is 1.8V chip. Unfortunately after programing with new bios same issue. It's charging but not powering on. Once power button pressed laptop goes into the loop with power light coming on for 10sec and off. I will keep looking for hardware issue.
