There maybe a fuse on the motherboard in the power supply circuit.
That would be a quick check to save putting in a new motherboard.
If you're not a technician, I would not attempt.
Board level repair or replacement would be the only solution.
You could also find the exact model Sony WAIO and swap the HDD.

Sir i have lost my mother board CD how i install audio and graphics drivers in my mother board no.GC11010N.86A.0311.2006.0420.1525

-Recomend 1. contact the manufacturer of your system Ask for replacement OS (usually around 15.00)
2. In some cases where it is a home built or custom computer it is easier to get a new graphics card with driver disks (ebay - amazon)

Cant find model number

On the bottom of the computer you will see a voltage (usually 19.5V) and a current rating (often 3.47A or 4.74A), With those pieces of information you can find a suitable replacement charger, possibly at your local computer shop.

If the port is suffering from a bad connection, you have to re solder it to the motherboard. I recomend you take it to a shop unless your an expirenced computer tech. Or you could replace the motherboard, but if your gonna do that, you are better off buying a new computer. I hope this helps. Good luck.
