Hi everyone,
I would much appreciate some help with my laptop!
I am having endless unfortunate problems with this laptop. First it just died and would not turn on what so ever, I got fed up of trying to repair it so just purchased a new motherboard from China. At first I assumed everything was fine again because it worked perfectly, although I did not have a battery, it was working fine off the charger.
I purchased a new battery for it from China and it arrived just a few days ago. Initially I still thought everything was fine because the battery arrived 80% and it seemed to work perfectly, then as the battery ran out I got the most frustrating problem of all, it would not charge.
When I put the AC adaptor in, it just cycles through charging and not charging every few seconds. I assumed the charger has gone, because I know this is a common problem with some laptops (it will run fine with the adaptor plugged in but will not charge the laptop)
But just before I wasted more money on a new charger I did a few tests. I still have the original motherboard, so I hooked up the AC adaptor and put the new battery in it, and it charged fine! Went back up to 100% within a few hours, and I was able to run the new motherboard off it again until it died.
So, I have narrowed it down to the NEW motherboard also being faulty! Would anyone happen to know how to fix it? I am sure it is possible to exchange some components related to charging from the old motherboard on to the new one, does anyone know what could be wrong?
I checked the voltage on the battery connector when the power cable is plugged in, on the one that wont charge it is constantly 19.5V, which is the full power of the adaptor and seems very wrong when the battery is only 11.1V.
The motherboard that will charge has -0.3V on the battery pins, until charging is activated and it goes up to 12V.
I apologise for this essay, but I would be so grateful if someone could help me. I want this laptop back!!
Many Thanks,
Graham
