If you have dc bench supply, then apply 1V,1A on shorted side of the coil and see what hots up. Else, it will be very difficult to isolate the shorted components.Comment

Hi everyone,
I have an Acer Aspire E5-772G with mainboard: Wistron Brook BH 14276-1M
Schematics are in this post: https://www.badcaps.net/forum/showpo...82&postcount=2
Boardview .brd file I found here: https://drive.google.com/file/d/15-n...Kw6L76hDj/view
The laptop is not powering on.
When pressing the power button, the power LED quickly flashes once and then goes off.
System seems to try running the power up sequence for 10 seconds getting stuck at step 6 [1.05V or 1.5V rail] before reaching S0 state... -
Hi folks,
DELL Latitude 5410, board number FDZ41 LA-J371P Rev: 1.0 (A00), schematic uploaded in different post, here is the link --> https://www.badcaps.net/filedata/fetch?id=3484415
When I connect it to a power ( DELL round charger, or USB-C ), LED on the power button starts flashing white, and the laptop doesn't do anything ( flashing slows for a very brief time in time when I press it, but it continues again ). Battery is not charging. While the charger is connected, I have few voltages present, but some of them are fluctuating, see attached pictures.
All I was able... -
Hello.
I have Lenovo B580 LA58 11273-1 with no reaction on PWRBTN, but charging. i found no EN signal on 5/3.3V IC. flashed bios and now have 3.3/5V,REG, EN but still no reaction to PWRBTN. -
I've a FXMC motherboard with a short on the DCBATOUT line.The moment the charger is plugged in to the board, it will block itself for protection. I have remove PR4402 for isolating the short, and making sure the short doesn't come from AD+_TO_SYS.
