Have you had to unsuccessfully press all possible keys on a laptop in an attempt to wake it up from sleep mode, or are you now, putting it aside, looking on the Internet through your mobile phone for ways to "revive" it?
Instructions
Step 1
There are two simple but radical ways to wake up your laptop. If you have not already done this, then try to start by briefly pressing the power button of the laptop - as a rule, any computer after that "wakes up". If it doesn't, press and hold the power button for a few seconds. This is usually enough to "hard" shut down the laptop. Pressing it again should turn it on.
Step 2
The second method, although trivial, works flawlessly in all cases. Flip the laptop over to reach the latch that secures the battery to the laptop case. Move it to the Open position and remove the battery. After a few seconds, plug it in, then return the laptop to its original position and press the power button, which will certainly bring it back to life.
