I can imagine the first time tech would think it's held in by a cable, but it's not. Have another tech show you the first time.
Having just installed a HDD in another laptop, GENTLE is not the word I would use to remove the cover.
I have loosened the 2 philips screws on the back plate to obtain access to the RAM modules but the cover will not come off. It appears as if there is another screw or catch in the middle of the cover - seemingly under the rubber foot. I gently lifted the cover to look inside but could not determine how to remove the cover. Can someone please help? Thanks
