    Water Damaged 820-2936-B

    Hi I have a water damaged 820-2936-b which i have ultrasonic cleaned the board and got it turning on etc. It runs really slow with laggy mouse but i think this is due to the voltage sense circuit. I have a schematic but could really do with a Board view file to locate components on board.
    Any help would be really grateful!!!!

          Sounds like a laptop.
          Don't buy those $10 PSU "specials". They fail, and they have taken whole computers with them.

          My computer doubles as a space heater.

          Asus Q550LF (Old main laptop, 2014-2022) - Decommissioned and stripped due to a myriad of problems, the main battery bloating being the final nail in the coffin.

              wrong section, ask a mod to move to appropriate section.

              it's amabcook pro logic board.

                      Hi diif,

                      Can you help me to identify the board based on the photos ?
                      I think it is a 820-2936b board and equal to this boardview K90i ? If this is correct then a lot of components (26) are missing on my board ? Can you see the photos also if i am correct ?

                      thanks for your reply

                              by RetroComputingGrotto
                              I have a water damaged Toshiba TV that was hanging nicely on the wall then over the summer we had a new multi-million pound boiler system put in and right where this TV was hanging is a nice new pair of water pipes for the radiators...

                              The TV hasnt been used for a fair few months but it was needed again the other day and needless to say, it didn't power on or show any signs of life (no standby LED etc). After checking the fuse in the plug (and that the socket it was plugged in to worked) I decided to get up some step ladders to take a closer look and low and behold! It looks like...

                              Hello friends, so I have got a "water damaged" (or cola/beer/coffe .. something dark and sticky) G513I system - which has the board and schematics from this thread. After cleaning up all the visible sticky residue with water and detergent (thankfully mostly on the top/keyboard side), I have a partial success. IPA was of no use for cleaning this.

                              Using a bench power supply on the DCIN jack (as it seems that the PSU keying pin is not wired at all - series resistor R6003 is not populated), and using a shoring wire for the power button (either pin 5 on CN251 keyboard, or one...

                              Dell Latitude E5590(La-f411p) water damaged
                              by estabilito
                              Hi,
                              I have water damaged Dell Latitude E5590 around charging ic.
                              Laptop was dead but i replaced some components like capacitors, resistors, resoldered charger(intersil 9538h) but traces under PQ904 dual mosfet(AOE6936) was burnt.
                              I rebuilt traces and both mosfets(PQ904 and PQ905) and after all this work laptop started turning on.
                              I dont have battery so i want to be sure if laptop behaviour is normal before buying.
                              On PL902 i have weird voltage around 5Volts, on battery socket voltage looks normal - 13.5v.
                              Is this voltage on pl902 normal?...

                              Like title says A2141 came in with Water Damage, customer desperately wants the data.

                              The actual water ingress doesn't appear too bad it sat for a day but was very dusty internally. I have no idea why L8504 was arced there is no apparent moisture there or around the LVDS cable; however, the LVDS to screen screw studs had popped off at some point and somebody tried securing it with kapton tape.

                              I had to create a micron wire pad jumper to reconnect the south side of the L8504 since the primary pad was blasted down to the vias.

                              That said after cleaning up the...

                              Lenovo ideapad D330-10IGM can't power on (water damaged)
                              by martyjelen
                              Hello, I have laptop Lenovo ideapad D330-10IGM which won't turn on. It was water damaged, but as I know it was clear water. I cleaned the board already.

                              Now, I noticed, that some component is heating up (see picture) there is a code GAASKJ on it. I don't really know what component is this and what is it's function.

                              It seems that charging works normally because current draw is about 1A and voltage is 19V.

                              Could you help me with it?

                              Thank you

                              BTW there is a flux on component. No damage.
