Over Flem

Ever since I bought this labtop, I have had problems with the power switch. It got blocked at times, BUT it was enough to remove it from the power and remove the battery. Subsequently everything worked normally. This was at least the solution since purchase and until lately. Then one  day while working on the labtop it made a sound as if the battery was empty, although the labtop was hard wired. I suspect, that the power switch could be broken. When I hard wired the laptop and tried to turn it on, the the power switch did not light up as usual. This did not happen as usual independent of whether  the battery was inserted or not. I have dismatled the labtop. 19V does get into the PC and at the level of the power switch board I can at times measure app. 3V. This depends on if I have applied the power button or not, but I am not quit sure what I am doing while measuring. On this board, I see printed BTC-202 B 94V-0 E220370.  How do I check, if the board is working properly ?  Could it be something else ? ... Meer weergeven
