    That could work actually. I think I'm gonna borrow the soldering iron and multimeter from the guys at work this weekend and try to find a solution. I've sorta' destroyed the BT connector that goes into the MB but I think it's salvageable. I'll see what I can do. Thanks again for the help.

    It has taken a while, but I'm here to add another keyboard mod to the list...

    There was this excellent thread with people presenting solutions (add tiny switches, soldering to the bluetooth connector, to the USB breakout board etc.), but I found none of them really satisfying. I decided to void my warranty, build a circuit and connect it to the useless „P“-Button already available. After all: „If you can't open it, you don't own it!“ - MAKE: Magazine ;)

    What you'll get:
    • A backlit keyboard
    • Brightness controlled by the „P“-button in 5 steps (off->brighter...->off)
    • Backlight turns off when LCD backlight goes off
    • Last setting is restored when backlight goes on again
    What you'll need:
    • The actual backlit keyboard (search for keyboards for the Aspire 3810T model)
    • A custom PCB (EAGLE files available)
    • SMD components (PIC 10F202T, N-channel FET BSS138 or 2N7002, 3x10k resistors 1206 types)
    • A PIC programmer (code + binary available)
    • Really thin wires
    • Low-watt soldering iron with a tiny tip and SMD soldering experience
    • „Carpet“/exacto knife
    • Hot glue gun
    Download the PDF here
    And the whole package with PDF, schematics, board, code and binary included here

    Enjoy.

    Wow, you are hardcore. Well done. Thanks for sharing. Are you a EE major?

    Thanks to the author and your post, I made my own one too! :)

    Check it out on my blog: gabroski: Upgrading the Acer TimelineX 3820TG with a backlit LED keyboard

    That said, my was a really simple mod since I've had no education in EE. Soldering was mainly done by an engineering buddy.
