In this guide I explain how to remove the keyboard and access both memory modules in a Sony Vaio PCG-V505 series laptop. The whole process will not take more than 10-15 minutes and can be done even by an inexperienced user.
Before you start do not forget to turn it off and remove the battery.
Remove one screw securing the keyboard. This screw is located between the lock/unlock and release latches.
Insert a small flat head screwdriver under the keyboard and carefully lift it up as shown on the picture below.
Move the keyboard towards the display panel.
Now you can access both memory (RAM) modules and RTC (CMOS) battery.
Sony Vaio PCG-V505 can handle up to 1GB RAM total. You can install up to 512MB stick into each slot.
You should use PC2100/PC2700 DDR SODIMM modules.
If your laptop looses date and time each time you restart it, apparently it’s time to replace the RTC (CMOS) battery.
You can easily unplug the RTC battery from the motherboard and replace it with a new one.
Before you remove the keyboard, you’ll have to unlock the cable connector on the motherboard and release the cable.
On the picture below you can see the cable connector in the locked position.
Unlock the connector and release the cable.
Now you can remove the keyboard and replace it with a new one if needed.
