Re: Asus x555ld possible CPU short

Yeah I'm not positive on a repair either. If I get the chance to use the right tools I will try to remove the CPU SoC just "for science", to see if the shorts disappear from the board. But I doubt I'll be able to put it back, BGAs are a nightmare indeed from what I've seen.



BTW that's on me, I was trying to repair the damn faulty HDD connector by resoldering it and, while I succeeded, I also succeeded in destroying the computer by plugging in the FFC from the USB and audio ports while the battery was on...

Re: Asus x555ld possible CPU short

Yeah it takes around 1A from the 3.3V power supply and the PCH heats up a little. Besides, I have 3 different shorts to ground from 3.3VSUS, 1.05VSUS, and a 1.05VS (after a MOSFET), all connecting to the PCH, so it is a goner.

Hello, I'm trying to fix my ASUS F555LD-(X555LD) laptop. I'm a beginner BTW and I would appreciate any help. This is what I have found out so far:[LIST][*]3.3V and 5V are ON, however, 3.3V goes through a soft-start chip to two outputs and one of them is shorted to GND. I have severed the connection to this chip and checked it is fine. The other path, shorted to GND, connects to the CPU and WLAN circuitry. Also to the BIOS, but there is no short there.[*]1.05V is ON, and there is no short around the regulator. However, there is a short after a bridge I removed, which connects to a MOSFET and the...
