Sorry younis but I no longer have the laptop nor its BIOS. -
Update: It looks like it's [URL="https://www.digikey.ca/en/products/detail/molex/5050040812/9693916"]this part, available from DigiKey[/URL]. Many thanks to DigiKey for their helpfulness!

Samsung ProBook NP767XCM-K1CA battery connector replacment source?
Tonight I broke the battery connector on the motherboard of this laptop and need to source a replacement. See pictures. The marking seems to read B6u. The sticker on the motherboard reads TCZRFN6X00230 P03AJD BA92-20746B 06 29. If someone could suggest a proper part number and source, I would be very grateful....

Thanks so much for that link! So it looks like my device is an AOZ5016QI. I'll order some from DigiKey and hope for the best.Leave a comment:

IC Identification and source or alternative for A&O AT002318
This is a power regulator/driver for the CPU of an HP 15-FD0008CA that is shorted and overheats. It needs to be replaced but I can't find a datasheet nor source a replacement. My many searched have come up blank. Any help will be gratefully received....

Yes, I believe so....Leave a comment:

Hello [USER="549403"]TheChief79[/USER],
I don't know if it's a common fault -- this was only the first or second Omen I have worked on. It sounds like your ENE has a short. Fixing that burnt area is a nightmare, BTW, if it has burned off the top layer of the MB like in my case, exposing the ground layer just beneath the surface.TheChief79...Leave a comment:

ASUS FX507 FX507-MP-GBM 6050A3467101-MB-A03 schematic request
This laptop powers on, keyboard lights for 1-3 seconds then powers off with charger LED flashing. I have the boardview and U3050 (9661A) or connected components have a short. I'm cautious about injecting voltage to locate the short so a schematic would be helpful. Attached is picture of the area....

This parts motherboard shows a component in the area I was trying to repair. anyone know what it is and where it connects?
Never mind. It's a 0.1uF/25v ceramic cap....Leave a comment:

Unfortunately, I have 1.4 ohms to ground on the HWPG line at the ENE, so no point in installing the new IC. That's after cutting the PGood trace to the IC to ensure there is no short in that area. I think I'm at a dead end....

HP Omen DA0G3EMBCD0 G3EA Boardview doesn't seem to correspond with the layout of this board, even though it has the same part number. The area was badly burned but I thought there was a small component connected to the ground stub just above the capacitor. Perhaps that's just a test point and there really was no crispy component that came off when I cleaned up the area.
I just received some TPS65295 ICs so I'll install one with nothing attached to the stub and see if it works. I need to mask off the exposed ground plane in that area before replacing the missing tracks (red). ...Leave a comment:

Yes, I know, thanks. TPS65295 is a replacement and easier to find. Does anyone have details on the missing component and traces in the destroyed area of this circuit?...

Re: IC suppliers in Canada or USA?
Sam_sam_sam, I ended up ordering one from www-electronicloop-de on eBay. I've not had good luck with ICs ordered from China and suspect they are reconditioned pulls made to look new. Thanks for your reply, nevertheless....Leave a comment:

IC suppliers in Canada or USA?
I need a ENE KB9028Q-C IC but everything I find on eBay or Amazon has long delivery times. Can anyone suggest a trusted supplier in Canada (preferably) or the USA for small quantities of ICs?
I usually buy from DigiKey but they don't list this IC. -
msecore Mini PC Fanless Computer schematic
Any suggestions for where to find a schematic for [URL="https://www.amazon.com/dp/B0B8GW3Y35?tag=reviewmeta0b-20&pldnSite=1&th=1"]this[/URL] or a similar Mini PC? The MB marking is GWHL2 VER B.
The one I had in for repair would shut down after 10-20 seconds and I believe the problem was a failing AC adapter. It had a 12v adapter but I mistakenly thought it was a 19v adapter so that's what I used for troubleshooting and it solved the problem, i.e., ran fine indefinitely. Customer (who probably thinks I'm an idiot) says I was lucky not to fry the thing and didn't... -

Re: Asus UX303U schematic
Hello PinGuy,
Did you manage to find a schematic for this MB? I have been unable to find one. Couldn't open the boardview file either using the latest version of the Fritzing program; I'm getting the following error:
I'll contact Fritzing tomorrow to pursue that but would appreciate any leads on a schematic if anyone has any.
I stupidly neglected to disconnect the battery before disconnecting and reconnecting the LVDS cable so blew something. <Sigh>...Leave a comment:
