Question about Sony VAIO PCG-V505CP Notebook

1 Answer

Dead Sony Laptop

Sony Viao PCG - V505CP. No power, no noise, nothing. 2.4v battery inside is less than 1v but that shouldn't stop it powering up no? Any common faults? The AC power supply is supplying correct voltage. Is power supply PCB available? What appears to be a hi wattage resestor reads o/c. 6.3A surface mount fuse reads ok.

If power supply is supplying correct voltage, then you do not need power supply PCB.

Try starting the laptop with AC adapter and no battery, if battery is shorting out you may get same problem.

Test the soldering joint on the AC socket and laptop motherboard, if there is a bad soldering on laprop ac adapter socket, you get same symptoms.

If it is none of the above, and the adapter is fine, then it is usually a faulty motherboard.

I have SONY VIAO PCG-71211W,the problem is that the laptop completely fail to start up,the light indicator is also not showing anything even if i put the laptop on charging.I tried removing the battery n...


The most common reasons for power issues are the battery, power jack and power adapter/cord.

Since you already removed and reinserted the battery, try the other options.

If you move/wiggle the power adapter at the point where it connects to the laptop, and the power goes off and on, the power jack is the problem.

The power jack is inside the laptop and either needs soldering or replacement. If a power jack problem, it should be addressed by someone knowledgeable.

If no change, the power adapter is probably faulty and needs replacement.

Hope this helps.

I can't find the sound driver, but you should be able to either 'update' the driver from the device manager, or download all sound drivers from the following link, burn to CD, and let the computer update from that automatically...

In battery is dead

Mostly this problem comes up if you dont shutdown your computer properly as in by offing it by holding the power button and stuff like that. What you can try doing is when you on the computer it should let you choose if you want to go to the BIOS menu or System Recovery and you go to System Recovery and if you would like reboot the whole computer or just choose to repair the windows and it will reinstall the windows files only which should take care of the problem.
