Inspiron N5010 does nothing when power button pressed, if power cord is attached then blue charging light goes out indicating that power unit has been overloaded and tripped out. If power lead is unplugged from laptop and mains supply, then plugged into mains again power is restored to adaptor and blue light on lead lights up again. Using Dell manual I have stripped laptop down to component parts. If mains adaptor is plugged into I/O board then charging light on lead remains lit. When motherboard ( including CPU ) is remounted onto I/O board, when mains adaptor is plugged in charging light goes out. Motherboard does not show any burnt area's or signs of damage to any component. Tried all versions of static discharge to laptop before stripping down without success. If the only solution is to replace Motherboard how can I order. The existing board includes 1GB ATI Mobility Radeon HD550v Graphics. The laptop is out of warranty.
