    Lenovo L15 Gen1 NM_C631 VCCSA short to GND

    Hello folks,

    I have an L15 Gen1 (NM-C631). It has all voltages so far, but not VCCSA.

    While searching I discovered the PQ1101 which burned down.



    I then soldered out the PQ1101 & PL1102 and the capacitors that come afterwards. Unfortunately there is a short circuit to GND (0.2ohms) on the pink marked line.

    Do you think the processor is broken? Or is it worth replacing the PQ1101?

          If the high side FET shorted, then you got 15V directly into the CPU. Pretty much game over at that point.

              Lenovo Legion 5 15ACH6H with possible short on +3VL.
              by SarcasticOP
              Hello!

              I am working on a Lenovo Legion 5 15ACH6H that will not take power when connected to the charger and will not turn on. The device was left in a car overnight when it got cold outside and no longer powers on. Inside the device was relatively clean and dust-free, and it did not have any immediate signs of liquid damage.

              The boardview files are available over at https://www.badcaps.net/forum/troubl...h-boot-problem. I am not sure of the etiquette...

              Need help pinpointing my short on this board (Lenovo) NM-D351
              by survivalbloke
              This is a Lenovo Thinkpad P15s Gen 2 with a board NM-D351. I'm having trouble finding my dead short to ground. I have the area narrowed down after much probing. You'll see in the boardview, there are two coils involved. I removed those coils and verified that that short is not on the mosfet side of those coils. . You'll see an arrangement on both sides of the board of 5 caps and one smaller one to the side. I have removed ALL 12 of these small caps and still have the short. Prior to that I injected at those caps with 1v5a and the short was only drawing 800ma so I could not see anything on thermal....

              Lenovo Thinkpad E15 G1 Gen 1 Short
              by cheebster
              Hello Badcaps, got a Lenovo Thinkpad E15 G1 Gen 1 NM-C421 with a short i've found on a mosfet. When plugging the USB-C meter, it cycles 20V-off-20v-off. On mosfet PQ1102 i see a short a 12ohm to gnd resistance. Removed the mosfet, measuring on the board gives same result. Checking on a previous post i saw this schematic picture, but not sure if what i'm seeing is normal and what would be the proper tests to do from here. Not an expert by any means by trying to learn. Thanks...

              Lenovo T14 Gen1 i7 10  nm-C931 (brick)
              by UADmytro
              Hey! I bought a Lenovo T14 Gen1 i7 10 nm-C931 (a brick). The previous owner said he got it on eBay as a password-locked device and took it to a repair service, where they tried flashing something. The result: it doesn't turn on.

              When I plug in the charger, the charging LED lights up, and the power button indicator blinks three times.

              I downloaded the firmware from the official website, but it's incomplete. However, there is a firmware for the embedded controller (MEC1663). I did a mass erase via OpenOCD, wiped MEC1663 along with the EEPROM, and flashed an image from the...
