Aspire 5920 after capacitor fix, doesnt work from battery

\015 Acer Aspire 5920 had no power, thanks to a post on here, I desoldered and changed 2 capacitors and it now boots fine with the power cable however, it will not boot with just the battery installed. I have checked the battery DC Voltage and it is around 16 and in windows, the battery is detected and 100% charged. Obv this is related to the capacitors blowing - perhaps there is something else on the board that could be preventing the battery from sending through its power.. any thoughts?P.S Please no basic solutions, this is not a simple fix.Thanks\015

Answers :

I'm pleased to hear the this fix worked out for you. The 5920 is also prone to quite a few battery charging circuit issues. The most common of which is the inability to run off of the battery. You can power the machine, boot to windows, and check the batter power meter. It could read 100% and the second you unplug the AC adapter the unit immediatly turns off. This is due to a blown fuse in the circuit preventing battery power from reaching the system board. I have included the best picture I could find. Its a little small but i have circled the defective component. You should try to replace it. This may be difficult becuase you would want to replace it with the exact same fuse. For a short term fix you can simple bridge the connection once the fuse has been removed to allow power through. This will solve your problem but may be dangerous to use without a fuse in that location.2c490f1.jpg
