For Online Computer Support, Ask a Computer Technician
Hello, welcome to JustAnswer my name is ***** ***** I'm one of the experts who will be assisting you today.What power plan do you want it on and which version of Windows are you using?May I start a remote session so we can work on the problem together from your computer?Please reply using the box below.Regards,Martin
So the screen is blank?
Ok, press and hold the Power button on the computer for a full 6 seconds, it should turn off
Once it's off, turn it back on and tell me what happens
Doesn't sound like it turned off, press the power button again but this time for 30 seconds
Can you go into any of the options at all?
Is it still under warranty?Power saving mode can happen if the computer isn't detecting the monitor (even though it's all in one it still works this way)
