Hello everyone! My hobby is fixing broken things. And, from now on, electronic things too
Thanks in advance for everyone who will tolerate my lack of knowledge

First of all, I'd like to mention that I'm a novice when it comes to laptop repair, although I do have some experience with soldering.
One day, my laptop experienced a severe stutter, and after rebooting, it failed to boot into Windows. I decided to disassemble it and found that the PL900 component was blown. Later, I came across a post ([URL]https://www.badcaps.net/forum/troubleshooting-hardware-devices-and-electronics-theory/troubleshooting-laptops-tablets-and-mobile-devices/96026-just-repaired-an-inspiron-15-gaming-7567-with-the-%E2%80%98acpi-bios-error%E2%80%99[/URL]) with the same problem,...

Hello everyone!
I'm having the same issue with a blown PL900. Based on [USER="302067"]reformatt[/USER] advice, I replaced PC902 and PC903, but after doing this, the motherboard is dead—no LED blinking. I then tried removing PC901-904 to check them for defects, but they were all okay. So, I started measuring adjacent components and found strange measurements on PQ900. It shows 3 ohms from the source to the drain pins and .001 in diode mode. Is this normal? I know this is dual mosfet, so I'm not sure if measuring method is correct. Can someone help me investigate further?reformatt
