Hi There,

The solution I found for my Laptop. One of my memory modules was not working.

The fix was to find the faulty Ram module and or replace both sticks.


1- Disconnect the power.

2- Turn the Laptop over.

3- Remove all the screw and pry open the back polycarbonate backing.

4- If you have 2 sticks of Ram remove 1 (to eliminate the one stick of Ram from being defective)

4a -Turn laptop over. Try rebooting.

4b - If that does not work, swap Ram and Try Rebooting.

I found one of the memory modules (Hynix Brand) had failed.

I replaced with 2 X 8GB Sticks of Ram and the Laptop works great.

Good luck
