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.
So I spent about 2 hours last night in msconfig services starting the laptop selectively. I narrowed it down to a single service that is causing the problem "Windows Management Instrumentation" This seems connected to WINMGMT. I tried to rebuild the Winmgmt repository but still no dice. (also when disabling winmgmt it mentioned IPHelper as a service using it, just in case that's relevant) The windows management instrumentation doesn't seem to be conflicting with other services as running it alone still causes the extreme lag and issues I have. WMI disabled in msconfig services issue is gone
