3 flashing lights on front of laptop



Problem with my laptop : When the on button is pressed, the laptop won't switch on. The 3 lights on the front left corner flash 3 times. The first and third light don't flash as bright as the middle one but they all flash in sync with each other. I tried it without the battery installed but that didn't make a difference. I tested the power supply output with a multimeter and it is giving approx. 18V. 


Laptop details :


Product Model Number : Compaq Presario CQ61-425SA
Product Serial Number : CNF9518Y7R
Product Number : VY440EA#ABU


Any help greatly appreciated.

    It was the charger. I bought a genuine HP replacement from a local computer shop the other day. It lasted less than a day :-) It was getting extremely hot to touch and eventually popped ! Ah I love HP, can't wait to buy my next one... oh wait... I won't be !!! Anyway, the shop I bought the replacement from send me a different charger, still genuine HP but about twice the physical size. Looks like it's from the old days but if it works I'll be happy.


    Problem solved.
