    CQ57 205SR motherboard problem

    So the symptoms are:
    1. Turns on by itself when connecting charger.
    2. Nothing on display.
    3. Caps lock LED blinks once every few seconds.

    As I know, CQ series has troubles with BIOS corruption. This blinking + no display is exactly the same that two of my CQ61 laptops had, which I fixed by reprogramming the BIOS chip.

    I have tried reprogramming this CQ57 BIOS too but no luck yet.

    Any idea where might be the problem or why does it turn on when charger is connected?

          Instead of reflowing/reballing, I would rather sell this machine.

          I don't think turning on by itself is a symptom of a bad solder so there must be something else wrong (too?).

              Problem with motherboard Gigabyte X570S Aero G - no detect RAM
              by iT0mT0m
              Hi,

              I have problem with detection RAM on this motherboard. When I install CPU(Ryzen 5 2600, 5 4500 or 5 5600G) DRAM Led is lighting all the time. I tried reflash various verion of bios using Q-Flash method and that not resolve my problem. I tried reflash bios by SVOD 4 but that not resolve problem too. All voltages is correct and I don't see any low resistance on coils and other elements on motherboard. I tried replace memory to other and nothing. I don't know where is a problem(maybe connections between cpu and rams socket?). Actually I have boardview for this motherboard and I have...

              ASUS X54H laptop thinks it's always charging even with charger unplugged
              by flat-earther
              The charging indicator light on my ASUS X54H laptop is always on even when the charger is disconnected.

              Windows also shows ''Plugged in'' when charger is not connected.

              This problem started year ago gradually, when unplugging the charger the charging light took several seconds to disappear, then minutes, and now almost always on even when unplugged for an entire day.
              Strangely, before sometimes immediately when plugging in the charger the charging light went away, and later came back with it connected.
              If I let battery run out and say it has 3% Windows will...

              hi to all
              I have the above motherboard on which I had windows xp I upgraded it to windows 10 everything went well just when it rebooted and got updates i saw a message for a very short time that windows is trying to fix a problem they found and then the problem was overcome and all is well
              the computer works normally without any problems on the internet and in everything
              but I found out unfortunately when I had completely cut off the power supply from the network and I went the next morning and plugged it in to turn it on when it went to boot a black screen and the cpu was working...

              Guide to transplant MEC1503 EC chip and EEPROM reprogamming for T14s gen 2 and X13 gen 2
              by acedogblast
              This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.

              There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as...

              Legion 5 PRO, 3 boards, same problem, NM-D562 Rev. 3.0 motherboard
              by hopkok
              Hi friends, last week I got 3 same boards for repair (NM-D562 Rev. 3.0), same problem, power button light up, but motherboard wont start.

              3,3V_alw and 5V_alw, 1,8V_alw and 0,75V_alw presented on all 3 boards, no other voltages. 1,2V missing and if I checked schematic right, I need 1,2V and than can be +3VS and +5VS generated after getting SUSP_N signal from KBC? or vise versa?

              I checked for low resistance on coils, no low resistance.

              Anyone with same issue like me?

              Thanks for any help.
