Re: HP ProBook 450 G3

450 G3, two long two shorts, BIOS corrupted. Got laptop as non-working.
Serial 5CD6104L89
Flashed BIOS from https://www.badcaps.net/forum/showpo...68&postcount=2 and it boots and works, but after BIOS update from Windows to new version, charger is not working. Flashed back via programmer, working.
Also, I thing there should be dGPU, but not showing.
Please suggest other BIOS

Re: HP ProBook 450 G3

it has EC bios....you can change them if they are identical, but you will have to write the 430g3 chip with the 450g3 content..

Thank you, somebody help me with the ec please

Re: HP ProBook 450 G3
