I have a Compaq CQ62 laptop which will not turn on. It was working just fine yesterday...
When you plug it in to the mains, there is no lights anywhere on the charger.
After a hard reset (removing charger and battery and holding power down for 30 secs) the orange charging light comes on. The light eventually goes white (fully charged) but when you press the power button, the power light flashes for half a second, then nothing.
No fans noises, screen action etc. Just the power light flashes, and after that it will not charge again....until you do another hard reset!!
