Take precautions while buying HP/ Compaque Notebooks...

I am a victim... There hardware have serious performance issues. I hardly used a compaque presario laptop 18 months... Its video chip damaged and is attached to motherboard. To replace a mother board, Rs. 20000 required.

Consult with one or two hardware techniciens before buying a HP/ Compaque PC's
