now remove the hdd by loosen the connector.

Be VERY gently with the connector. Use IC pliers to loose the connector.

mine was already broken when i bought the laptop.

after you removed the connector, lift the hdd to one side and pull ( gently) it out.

also remove the connector ( flex cable) attached to the mainboard. see green circle in second picture.

to loosen this connector use a spudger to lift the lid (lid of connector.) up. do it very gently.
