Re: Alienware 15 R2 LA-C912P no CPU power

Power consumption stays same with ram /without ram-this means system is not reading ram. So you have to check voltage on ram slot pins.

Re: HP 15-ac126nv no power at all

Yes, you need to replace PU2/PQ7/KBC-all at the same time. Doesnt make sense to save a dollar or two and risk the repair going bad again.
