If you put a capacitor where an inductor should be, no current is crossing and no signal is going. Unless you soldered inductors where I highlighted you aren't going to see a POST, if that's the issue. Let's keep being positive 😀

I have the board but I have no capacitor tester. Some smd are brown- caps, others are grey- filters (I have 32.2 ohm reading on them). Some you have resoldered are filters and not capacitors like the one on the lower right corner of the first circled missing part. Lower right to that one is a filter …

That's a nice looking laptop. Is the screen all scratched up or just a weird artifact from the picture? I have a laptop with the same issue, not artifacts ;) Basically the glue that is between the lcd and the outside layer (protective?) alters in time and has a lift up/ bubbly effect. There's a …

Could it be that a filter in beteween has gone bad and is going toward the resistance, high ohm, instead of 0 ohm? This could explain the 5 to 3.48V

Interesting case. Looks like a full height version of the low-profile cases I have (the two on the left). At least, they seem to share a very similar design language. The one on the left is my 286/16 and the other is my 386DX40 PXL_20210305_011600220.jpg My heart felt warmth :) That is beautiful. I …

Can I build a pc from spare parts? Yes, a few. Some have a new pc and have only that, maybe two and a laptop. Some others have been collecting for years and have vaults of spare parts including a G.E.C.K. or two.

I had that d1d0 before, trying to check RAM. Bad trace or NB issues, Nb to cpu... I have a 939 m/b and the NB definitely has voltage issues with d1d0. Have you checked ram voltage?

I installed WXp Sp2 on a GXM 200. Worked but I had an issue with explorer.exe crashing and I couldn't solve it. I dropped Xp because each installation was like 60+ minutes long. Companion chip was a Cx5520. Also ACPI was supported in W98SE but not in W2K and Xp, annoying.
