Dell G5 15 5587 1v shorted.
Hello, i had a [B]Dell G5 15 5587 [/B]with[B] la-e993p[/B], which had a shorted PU100 (+1valwp) with burned out power input traces. Fixed the traces, replaced ic and computer boots up!!?! (after long time waiting about 3-5mins for post). Computer ignores bios updates, does nothing, at the moment getting this error "Error sending End Of Post message to ME: HECI disabled, proceeding with boot!".
My question would be is this problem solvable with bios dump fix and reflashing it back ? Many thanks in advance.Hello, i had a [B]Dell G5 15 5587 [/B]with[B] la-e993p[/B], which...

Lenovo Yoga 910 with NM-a901 board
Hello, I need advice, computer turns on only with battery plugged in and usbc charger, but charger stays in 5v mode and 2.4-2.5A, does not switch to 20v, by that, GPU core does not start. I know computer starts because it goes to sleep after pressing button, pressing caps lock turns on the light. I have all power rails present, no shorts, no liquid damage. How board communicates with charger and tells to turn on 20v mode? Thanks in advance.
Attaching schematic.

Re: Macbook A2442 820-02098 no battery charging.
No, as i said, 20v from charging port goes to cd3217, but not pass it .
Now random thing : UR500 becomes hot, it was not earlier.
Edit: battery connection broke off. resoldered it, waiting for UV to cure paste.Last edited by Lukosiukas; 05-19-2023, 06:13 AM.

Re: Macbook A2442 820-02098 no battery charging.
When you have 5v power delivery contract from the outside power supply, what is the voltage to ground of PPBUS_AON?
12volts with battery disconnected and 11.4 with battery connected.
What is the voltage to ground of PPBUS_AON when the PD contract is 20v ?
11.4volts
SDA/SCL 1.78v
Now im thinking that isl9240 could be bad. Could cd3217 break ISL after liquid damage?

Macbook A2442 820-02098 no battery charging.
Hello, i need assistance -
Got 820-02098 with liquid damage 2 cd3217b12 was damaged. Replaced both (On schematic uf400 for typeC and u5500 for magsafe), after replacing, computer turns on, works, but no battery charging(battery charge goes down). Checking with usbc power meter after reassembling getting 5v 1a power draw on magsafe, after reconnecting cable getting 20v 0a power draw. When power meter shows 5v, I'm getting the same 5volts on on PPDCIN_AON, but after reconnecting magsafe (20v on power meter) getting 0volts at PPDCIN_AON. Need help to understand why im not getting 20v on PPDCIN_AON...
