          Tanks bios worked good, but unfortunately laptop has some hardware damage , cpu partialy dead due to overheating
          over the years that's why its freezing in demanding apps. Draws over 6amps on the bench PSU ( original charger is 4.74A) . Changed all cpu and GPU mosfets , plus main mosfets , still power draw is over the limit , cpu gets very hot very quick , and it freezes in any task .
          Case closed . Dead!

              HP Pavilion Gaming Laptop 15-ec2523nd - Dimm2 slot disabled after corrupt bios repair? Advice requested.
              by Bloodhoundje
              Hi everyone,

              I have been doing hardware repair as a hobby for some years now and recently decided to learn about repairing laptops as a fun challenge.

              I managed to get my hands on a "HP Pavilion Gaming 15-ec2523nd" notebook that only shows a white power LED and doesnt respond to anything.

              After initial testing I concluded the bios seems to be corrupted since all voltages are normal and there are no shorts. HP has a feature for a bios restore from USB with winkey+B for this model. This did not work.

              I have desoldered the bios chip (GigaDevice...

              Lenovo laptop does not turn on, what does this number mean in a BIOS chip?
              by thxd43
              Hello, first of all, excuse me, I am using the translator, English is not my native language.

              I have a Lenovo ideapad 330S - 14IKB laptop.



              The tablet did not recognize me when I connected it, so I checked the device manager and I realized that there were many with the exclamation mark, so one by one I began to update their drivers until the sign disappeared of admiration, I even updated the BIOS, and the laptop rebooted normally and worked, so far so good, but the tablet still did not recognize me, I read on the internet that it could be due to a...

              Request BIOS files to flash Toshiba C55-A-1TX laptop
              by YvD-Electronics
              Hi all,


              I need the BIOS (bin files) to re-flash the BIOS chips on a toshiba laptop.

              Why I am pretty sure I need this to repair?


              1) Power supplies seem OK.

              2) Battery has been replaced, is charging well ... also not the CMOS battery CR2032, also not OK without RAM, or 1 or the 2 RAM modules (RAMS are OK).

              3) Laptop does really rare (seems random things) with the 3 leds (power, net, ...)

              4) In the past, when trying to restart 100 times via power button, it was sometimes succeeding, now no more.
              ...
