Hi masters, anyone can help me with BIOS? Long story short, spilled unit, did not start at all. Found two burned resistors in 3.3/5V step down controler. Now unit start, but it takes 30-40 second to get a picture and than FANs start run at full speed and turn off after 20 seconds, so could be ME corrupted...

Yes, both devices work everything else probably ok, I mean, I hear intro melody and keypress click sound, DTMF tone, power on off... all ok.
On desk is nokia 2220 slide, and I check all screen connectors and components arround it, measure voltage drop, but all looks ok. I suspect on slide flex cable, but it look ok and white screen is not interupt while flexing board, pushing conectors, and sliding up down. In attachment...05-13-2024, 03:43 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 johnbetonHello,
I have a A1706 with 820-00923-A board. The laptop came in with non-working keyboard. I bought a new top-cover with keyboard and transfered everything to the new topcover.
Since then the macbook will not charge or power-up. Before replacing top cover, I started the macbook to test, and it worked fine apart from keyboard. Then shut it down and did replacement.
This is what I measure so far:
Resistance from F7000 to ground is 123 Ohm on pin 1 and 2
PPBUS_G3H = 0,79v
PPBUS_HS_CPU = 0,79v
PPBUS_HS_OTH5V = 0,79v

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 -

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 -

I have made two dumps of this bios, with the bios chip removed from the board and the hashes match on both dumps, but I cannot find the DMI information in the dumps except for the Windows product key, so I think it is corrupted. I have downloaded two bios updates from the Lenovo support site, but they contain small .PAT file, and 4 subfolders containing .FL1 and .FL2 files, which I don't understand enough to figure out how to use to fix my dump.

by ScarfycakeHi all,
I sent my [B]ProArt Studiobook 16 OLED (H7600, 12th Gen Intel) [/B]to the local repair guys to have a very simple DC in port replaced. I sourced the part myself on accessoires-asus (french company) after struggling to find the right part in the UK. It looked completely the same to the installed part from what I can tell. Originally the only issue with the laptop was a bad / loose DC connection, and so the computer and battery acted completely normal aside from a very poor connection that would fail at certain angles. After the repair was completed I brought it home and used...5 PhotosToday, 08:16 AM -
