by kingblade20Hi,
My M3401QA does not power on properly: no display (all black) and with white LED charging port blinking slowly (once every ~3 seconds).
Checked several points across the board and supplies are up and running but I need to double check when I get schematic.
Result is still the same even with DC jack inserted and battery connector removed.
Tried flashing the latest BIOS as of this date to no avail which I suspect has something to do with DMI but tools could not run properly on my machine and couldn't find manual copy of DMI through hex editor and not sure...-

by matheus30When I took it out it broke, and I want to get the same one or one of good quality.
Where can I buy it? On AliExpress they do not indicate the maximum amperages, and on Mouser or TME.EU it is impossible to search without having the exact reference.
Inductor needed:
It is the PP5V_G3S Coil of an A2159, 820-01598 (L7670)
On the front it says: 1R5
and in the schematic:
1.5UH - 20% - 12.5A - 0.017Ohm
PIMB062D-SM
152S00268
Can someone tell me where to buy it?
Thank you so much.Yesterday, 11:44 AM -

by sauceHi,
I bought a faulty A2289 for myself.
The USB-C meter was stuck on 5V.
After remove the board the U3100 was corroded and also around but quite light.
So I clean the U3100 and see R2834 in bad condition and its value was not good.
I replace it and not the USB-C meter shows 20V, the fan is spinning, CPU is hot but nothing else no picture.
The USB-C meters shows a very low current with all connected. It starts at 20v few mA and then stays at 20v 100mA.
How mush current the board is supposed to take without nothing...05-19-2024, 12:20 AM -

by jm1234Hi,
I'm troubleshooting a power supply board and one opto coupler seems shorted. It's a through-hole, marked with 3 lines:
1223
816A4
W
I'm not sure what replacement to buy for it. It resembles LTV-816 ([url]https://www.tme.eu/sk/en/details/ltv-816/optocouplers-analog-output/liteon/[/url]), but I'm not sure it's 100% that. The data sheet shows multiple sub-types like 816M, 816S, but 816A is not there.
I do have other functional pieces on the same board, so I could do some measurements on those, but I'm not sure what to check.
Any idea appreciated.Hi,...Yesterday, 03:30 AM

by ianbakHi,
I have an HP 255 G8 that runs for as long as its battery holds charge but won't accept AC power.
I have partially diagnosed the problem and the issue seems to be that there is no ACDRV output from the BQ24735 to turn on the two input MOSFETs. The 24735 has a VCC of 19.57 V, the ACDET input is at 2.93 V and the REGN 6V LDO is outputting 5.98 V, so everything looks good - but ACDRV is stuck at 28 mV.
I've already replaced the 24735 and both input MOSFETs and nothing has changed.
I'd appreciate some suiggestions as to what to try next.Yesterday, 08:45 AM -
