ProBook 4710s not turning on (blinking power light)

[plloyd]

Hi all,

  I was wondering if anyone knows why my ProBook 4710s won't turn on.  It currently has a blinking light on the Power button.  It blinks about every second.  Even when I took the battery out, it still keeps blinking!  Any help would be appreciated.  Thanks!

remove the battery, other peripherals and the AC adapter... press and hold the power button for 20 seconds... plug the AC adapter only and turn on the notebook....

I'm having the same problem with my HP ProBook 4525s. It doesn't come back from sleep mode, and the CapsLock light blinks.
