Re: DV6-1200EH 2 caps flash
2 flash code mean bios issue, but with hp flash code you never know, you can try to reflow the chip and see what it does.The Night Drop Down, I Will Keep Try Until..., You Never know.

I know I've been a little scarce lately (like the last 2-3 years), but I'm still here and still doing my thing with fixing PSUs.
For today's considerations, I have a Seasonic B12 BC-550 [A551bcafh] 550 Watt ATX power supply for you (click on links for full size images).

My issue isn't massive, but I'd like to get this solved since I'm trying to fix a friend's laptop.
A botched BIOS update by Lenovo bricked this laptop, so I used my BIOS programmer to reflash the BIOS on it and saved it from an early demise. All is good now, but the BIOS reports the S/N, MTM and UUID... -
Normally, I never post repairs this quick after I do them, because… I am usually very slow.
But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. 
I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...

Hey guys, bit stumped with this laptop after replacing 2 blown components i.e., MP86493, MP2979A.

Hello,
First, I am a complete noob with high voltage stuff. I'm learning, but I need help by someone looking over my shoulder.
I recently came into posession of a Heathkit IO-4205 5MHz Dual Trace Oscilloscope. The documentation is copyright 1978. I'm told it works.
I opened it up to check the caps before I applied power, and found the following black caps and wanted to know what they were. They are on the power supply board. I was able to read the name and model and came up with, "Nytronics 162J-1, 0.1uF, 20% tolerance, 2000VDC."
