So it's a basically new Asus gaming laptop with an inbuilt battery. Last night I was drawing on my graphics pad and all working well. When I turned it back on this morning it got to desktop but the windows bar was stuttering, I couldn't see the mouse cursor and couldn't really do anything. It seemed to be lagging big time. I tried to open task manager and this took nearly 2 minutes. When it finally opened it was unresponsive. The battery still was at 50%. I restarted into safe mode and laptop worked fine on battery, (so likely a software issue). Done a virus scan in safe mode and nothing. Then though to restart it plugged in. Laptop ran as normal when plugged in. However as soon as I unplugged the power cord and it wen to battery it started to lag again and be unresponsive. After that plugging the cord back in did not fix the issue and a restart while plugged in was required. Any Ideas? Has anyone encountered this before? Also changing battery profiles did nothing.
