      Yes, as i said before it powers on ok...no post (no display). Symptoms are for a bad soldering gpu chip...but reballed twice..so i can rule that out.

          Thanks for the reply Francisco..ive got that schematic (BL10G) but the board is BL10 its an older version rev 3...not BL10G.. the markings and chip numbering is different..there might be some components in common but they have different markings...thanks again!

          this is the exact code : INVENTEC Berlin 10 BL10 6050A2332401-MB-A03.

                If bios chip have data corruption, the only way to know, is de-solder it and reprogram with new good data.
                Regards.

                    Re: toshiba satellite L650 Bl10 UMA

                    Ok...back to this project...abandoned due to unabled to fix....
                    So it powers on, stays on for 20 secs..then powers off...then powers on again...its a power loop of 20 sec duration...

                    i removed the bios chip and rewritten it with a newer version of fd...no change.

                    Can anyone help please?
                    Could this be a power failure or a bad cap...as i said before..i removed and swapped 2 bga chips (intel) because i thought it was a gpu fault but no improvement.
                    The bga gets hot though...after 15 secs of power...this model seems to have poor heatsink system...the bga has no copper shim or heatsink!

                    please help with a hint.

                    once again: no display....power loop after 20 sec.. could this be a power issue? tested and battery is charging.

                      that could be bad CPU, try swapping with a known good one

                          well what happen is that a abnormality is beeing reported to the KB and KB is shuting down the mobo , so i would go for the main thing , chek all S0 when pressed ON (chek all coils and report us voltages present .) after that we can start rulling out some outher options , but does values would be very apreciated to help you out !

                            wouldn't hurt to reprogram the bios first.
