Laptop dead after replacing BIOS Chip

[bigbadbios]

Hi all,
I have an ASUS ROG Strix G533z 12th gen i9 laptop that had no video.
I suspected BIOS corruption, so I took the main BIOS chip off and replaced it with another one that had a clean BIN I bought online.
After doing so, the device is stone dead. Even with the original chip fitted back.
I sent it to Northridge Fix (I am based in US) and he said no activity on thermal cam and no power issue is not directly firmware related.
Can anyone help? I'd love to save this fairly new and powerful laptop.
Thank you!

It likely just needed a CMOS reset, but I suspect you have introduced another fault if it went from powering with no video to completely dead. Repairers like NorthridgeFix will pass on your repair pretty quick if they find you've messed with it prior to sending it to them. They are just too busy to go down a potential rabbit hole.

I'd suggest sending it either to someone who will spend some more time on it, however it's a bit of crapshoot for most of us with Asus due to the limited or non-existent documentation/schematics/boardviews for their products. Other option is to send back to Asus directly. They'll likely just swap out the board so it'd be an expensive repair with an I9.

I really appreciate your response. I did try to fully drain the system by taking the battery off for a couple hours more than once prior. And tried swapping memory. Strangely enough, there were some other people online with similar models of a similar age that had the same issue(hoping it is not a dead GPU/chipset). Do you have any suggestions for someone who would take a more in depth look at it?
Thanks

I'm in Australia, not sure who is available in the US for that kind of repair. Someone else on the forum that is stateside may be able to help. Or send it to Asus.

Most faults on Asus laptops are faulty power buttons in the keyboard (they are notorious for this), or bypass caps randomly going short somewhere on the board. Asus make great routers and desktop motherboards, but their laptops? Meh.
