The macbook charger has a green light, the battery has been replaced and OS reports Normal status but Not charging. After cleaning a corroded capacitor it crumbled off the board. There...-

diagnosed - issue is the display/power button
on the board, with the multimeter I noticed there is a short to ground. as the red wire has 0 ohm to ground.

by osblnHello everyone,
I like to repair everything I can get my hands on.
A friend gave me a laptop that fell down while it was switched on.
Now the display remains dark and the laptop no longer boots up.
Since my English is not so good, I worked with a translation tool. Please excuse me if something is not translated correctly.
Normally this device is not in a price category where you have to grit your teeth, but I really want to find the error and learn something in the process
Details of the device:

Had a coil which was shorted to ground. Injected 1V and watched this ic get hot under thermal cam. Removed the IC and the short was gone. Now its .3 voltage drop which is good.
So basically i need help identifying this IC.

by ResoluteHawkI have an Asus G14 (GA401QM) that has a power issue. Originally the board had a shorted 5V rail and dead EC. I reballed a working EC, soldered it on, and I resolved the 5V issue by replacing the APL6012 and the low side 5V mosfet. Resistances on all power rails are healthy now, but 20V does not make it through the first MOSFET. 20V is present on the drain of the first MOSFET, but there is no voltage on the gate or source.
When diagnosing this issue, I thought that the issue was due to the BQ24800 chip not outputting the correct signals so I soldered on a known working chip and the...05-08-2024, 01:30 PM -

by ub6ib969Hi,
working on a ASUS ROG STRIX GL702VSK 60NB0DZ0-MB1260 that does not power on. At the PQ8900 PIN2 (P_CHG_ACMOS_G_20) I am receiving 24.7V and PIN1 (P_CHG_ACMOS_S_20) 20V, however when I place the PQ8901 P_CHG_ACMOS_G_20 it drops 0V. I don't have the replacement mosfets ( N-MOSFET QM3058M6AC PRPAK5*6
UBIQ) however will any N-channel mosfet with similar parameters work ? I also found that PCI8703, PCI8701 are shorted. any help would be grateful.05-07-2024, 04:34 PM -
