My HP ProBook 4535s has gone into sleep mode and wont wake up.
The on/off button is flashing, but the laptop isnt responding.
Ive tried pressing the quarter moon key; holding down the on/off switch; and plugging the charger in and repeating both of these.
Does anybody know how else I can wake it up?
Thank you.

No idea about the real cause. But you can try to remove / reinsert the battery pack. This helps on my son's Windows 8 laptop.

When you remove the battery press and hold the start button for about 30 seconds to discharge the board.  Put the battery back and start it.  Go into control panel and change the sleep setting to -0- until you get a remedy.
