First of all turn off the laptop and unplug the AC adapter.

Unlock and remove the laptop battery.



Loosen two screws securing the memory cover and hard drive cover.

Lift up and remove both covers.



Under the memory cover you'll find two memory modules. I will leave both memory modules connected to the motherboard.

Toshiba Satellite L775, L775D, L770, L770D will take up to 8GB RAM total. You can install up to 4GB RAM module into each slot.

The CMOS battery also accessible under the memory cover. It's a regular coin battery. Model CR2032.



Remove one screw securing the DVD drive.

Pull the DVD drive to the left to disconnect it from the connector board.

Remove the DVD drive.



Slide the hard drive to the left to disconnect it from the motherboard.

Lift up and remove the hard drive.

Toshiba Satellite L775, L775D, L770, L770D laptop has a regular 2.5" SATA hard drive installed. It can be replaced with a larger capacity 2.5" SATA hard drive or SSD (solid state drive).



Carefully lift up the right side of the keyboard bezel with a small flat head screwdriver.

Continue removing the bezel with your fingers.



Remove four screws securing the keyboard on the top.



Carefully lift up the upper side of the keyboard and turn it upside down on the palmrest.



Now you can access the keyboard cable connector.

In order to release the cable you'll have to unlock the connector first.

In the following two steps I show how to unlock the connector and release the cable.



The keyboard connector has a white retainer.

You'll have to lift up the left side of the retainer with your fingernail. Do not apply much force. The retainer opens up at a 90 degree angle.

The retainer must remain attached to the connector base.
