I've been searching all over the internet and these forums in particular and I just can't seem to get any answers regarding GPU upgrades for the Clevo P150HM. Neither can I get any real info on the difference between the HM and the EM model - the EM seems to be the much more talked about model.
Anyway, my current GTX 580M is causing a black screen very occasionally and I decided to purchase a used GTX 980M (N16E-GX-A1) from aliexpress as a replacement.
The seller isn't giving me much information and I am unsure if they've flashed the vbios on this card themselves, regardless of that I cannot seem to find a custom BIOS for this laptop either, the closest I found is P150EM_17_11_PM_v2 which is obviously for a EM not a HM model, again I don't know much about these two models and if attempting a flash with that BIOS will brick my laptop.
The 980M is the correct form factor, it fits in perfectly and even warms up when I turn the laptop on, I can see the POST screen display but then it simply maxes the fans and beeps out until it shuts down. It would seem to be a pretty clear indication of incompatibility.
Model: Clevo P150HM
MB Series: P150HMx
BIOS Revision: 1.01.14
KBC/EC Firmware Revision: 1.00.12
Another version number listed (not sure for what): 2.10.1208
I understand this is both an old subject and an even older laptop, but I would be extremely thankful for any help available and I am willing to drill down to create my own custom BIOS if necessary but I just need a point in the right direction.
Failing all that, its not the end of the world as they've already agreed to a return and refund if I can't figure this out.
