I have an HP mini laptop. I woke up the next morning and realized I accidentally left my laptop on the whole night and now it won't fully recover from sleep mode. It's been about a day and my laptop still isn't working. It turns on fine, but all I see is a black screen and the mouse. I have a lot of work I need to catch up on and I can't waste anymore time. I can't afford it get it professionally fixed. I've tried everything, what more can I do?
Unplug the power cord, remove the battery and then hold the power button down for 30 to 60 seconds. Then reattach the power cord and attempt a boot. It worked for me! Just shutdown, put the battery back in you're good to go. Worked for me so definitely worth a try.
