    Damn L850/C850...I`ve repaired few of them by reflowing vram modules...those boards are very sensitive to heat...Usually gpu dies...

        Ah well...who would know...gremlins maybe I usaually fix them by replacing gpu...
        I think C850 would be successor of HP 6735s in number of repaired units,at least in my shop...

                      No image even after replacing GPU on this model - failed Intel PCH. You will also notice that it gets very hot on boards that have no image. On working boards it is just warm. Either way, it is very bad design on this laptop (and many others), the PCH has no kind of cooling, and thus it fails.

                        Toshiba Qosmio X755 Charging problem
                        by delphi_firebird
                        Hello Guys,

                        I received Toshiba Qosmio X755 that has a charging problem and I'm stuck trying to figure out the problem.

                        - When battery is unplugged i works without any problem.
                        - When I plug in the battery after plugging in the charger, it works correctly and the battery is charging.
                        - When I plug in the charger after inserting the battery, it stops working. ( voltage dropped and consumed 8A, reaching the maximum capacity of my bench power supply for 5 seconds, and stop working after )

                        Can you help me diagnose the problem? I have attached...
