Re: Alienware 17 R3 (LA-C912P) Powers on then powers off after 4-6 seconds

Re: Acer A315-55G / DA0ZAWMB8E0 not charging

Not true since ACOK can be pulled up to an external supply derived from the main power rail. So it may not be high before the DC-in MOSFETs are turned on, but it's not necessarily pulled low by the...

Re: Macbook Air 820-00165 A 14 V on PP3V42_G3H

The original inductor uses this kind of package. It is not the same thing as a ferrite bead used to filter high frequency noise though.

Re: Macbook Air 820-00165 A 14 V on PP3V42_G3H

The inductor is a critical part of the buck converter, it cannot be replaced by a ferrite bead.

Re: Macbook Air 820-00165 A 14 V on PP3V42_G3H

Measure on the output of the inductor not the input.

Re: Software to analyze Video RAM faults on graphics cards?

I used it on 8800 GTS G80.

GTX 260 won't be supported as it is a GT200 core, however there is some support for G9x.

Re: KB and Trackpad only work in safe mode - 820-4924-A Macbook Pro Late 2015 A1502

Re: Ask HP ProBook 450-G2 No Backlight LA-B181P

Cable is suspect if it's not been replaced. Voltages should be checked on LCD side to confirm.
