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.

The battery is fully charged, and the ac adapter is plugged into the laptop, when i push the on button the laptop will not start


Remove the battery and power source. Remove the RAM and hdd. Power up with the power supply and it should do something. If it does, replace the RAM and hdd it should now restart. If nothing, check the GPU.

How do I get the battery out of my acer laptop


Your Model of Aspire has a different battery release method, see attached pic on how to do it. This is a pic from your User Manual, you can download it from here Download Acer Aspire E1 572
Manual
. I suspect that the information you have been given regarding battery removal and passwords refers to removing the cmos battery as in a PC in the hope that it will clear Bios activated passwords.

Bluetooth & sound


Generally, connecting phones via bluetooth to a laptop just allows for file transfer between the two devices. It is not to input sound from the phone through the speakers of the laptop. You would need a bluetooth audio device for that such as bluetooth speakers or headphones

Freezes on the warm boot screen MC9000


This can be for a number of reasons.

First thing would be to try and cold boot the device:-

Remove battery half way, hold power button and trigger, push battery in fully until click and then release power and trigger

If that fails next thing would be to try and re-flash the operating system. This is done by using an SD card and loading the latest operating files onto it. The SD card slot is located under the keypad. A cross head screwdriver is required to remove the keypad. Search on symbol software download site for the latest. The download also has a readme with detailed instructions. Once the files are on perform a cold boot.

Remove battery half way, hold power button and trigger, push battery in fully until click and then release power and trigger. Drop the terminal in a cradle so that it runs on external power.

Hope this helps.

How do I start bluetooth on the qosmio g25-av13?


Try the ff:

1. Are you also using a wireless internet? If you are and you cannot also connect on wireless, make sure that the wireless is enabled on your laptop. On the left side of the laptop there is a on/off switch push the switch to on. (beside the usb port).

2. if it is already on, make sure that the bluetooth is enabled also, you can check it on control panel, system, hardware, device manager, bluetooth, right click on bluetooth driver, if you see enable bluetooth click on it, if you see"disable bluetooth" that means it is already enabled.

3. If the above is already configured, lastly, look for the bluetooth icon (bluetooth manager) on the lower part of the screen on the taskbar/tray if you see the bluetooth icon, right-click on it then click "Enable Bluetooth Radio". Now, if there is no bluetooth icon on the tray at the lower right of the screen, go to Start, Toshiba, Bluetooth, Bluetooth Settings, inside the Bluetooth SEttings, click on Bluetooth, Options, CLick on Enable Bluetooth Power, also, inside the Tray Icon (still inside Bluetooth Settings) select an icon so you can always see the status of your bluetooth on the Tray and you don;t need to do and check everything everytime you cannot connect via Bluetooth.

Hope this helps.
