[OPLINTECH] FWIW 2012/2013 AWE Early Literacy Station Info Try again with photos

[Bob Neeper]

Wanting to reconfigure the s/w to a linux version needed the UEFI/CMOS password.
To reset the password I wanted to remove the coin battery.
It is well hidden, on bottom of the mother board.

This voided any warranty so did at my own disk.
May have made a brick if not careful.
Not for the fainthearted or probably anyone not experienced. Scared me and I'm 
fearless.
Just something I did to pass the retirement time, can't always do genealogy.

First photo. Remembering to use static sensitive procedures, I pretty much did 
this.

Unplugged all connectors and placed the unit face down and remove the 4 screws.
Using 2 small screwdrivers carefully separated the back cover.
Inserting one a bit and turning clockwise generated a click, which is a release.
Used the second one to keep the plastic separated, moving along with the first.
Started at the bottom of the unit and worked around.

Carefully peeled back some of the foil and cloth tape from the metal plate under 
the green board. Red circles.
Unplugged the connector from that board. Blue circle.
Removed 7 screws, most labeled 1-M2, 2-M2, etc. Green circles.
Carefully removed the plate.

Second photo, I.

Removed 5 screws. Green circles (not the one with the arrow yet).
Spread the black fins and only loosened these 2 screws. Rose circles.
Loosened the 5 heat sink screws. Blue circles.
lifted the heat sink and removed the last screw where green arrow points.
Put on some thermal paste and tightened only 4 of the 5 heat sink screws.

Gently lifted tape. Tricky to get the tape free. Red circle.
Gently used finger nails to pull black lock strip towards board edge and 
unplugged ribbon cable. Blue arrows.

Lifted board, moving cable (in white circle) and removed the coin battery for a 
while.

Replaced the battery.
Replaced the main board, but not the metal plate.
Powered up and used F2 to change the password. May have needed to do this twice.
(Found if I powered up and got a white screen I didn't have the ribbon cable in.)
Cycled power a few times to test the new password worked.
Replace the metal plate, connected it's board and retested.

Then closed it up.

Found the SATA configuration had to be correct to match the HD to allow s/w to 
boot fully.

Changing the hard drive would be rather easy.
