Battery Not Detected
I have encountered this problem twice. When I am using my laptop, suddenly it's lagging. Then i checked the battery bar and it show "X" sign.
I recalled that it was 100% charged but then it suddenly turned to X
Any solution of what's going on? hopefully i don't need to go to service center since i don't have my warranty anymore and it'll take very long
for them to fix it
Thanks
