Ill be honest, Ive never owned a portable before until recently.

I finally got around to recapping it. Recapped it, now trying to figure out this weird issue.

Plug it in with a 2amp cord. (no battery), it does the click-click. Hit a key on the keyboard, screen comes on to a zebrastripe/jailbar pattern, no chime and it shuts off. Wont power up again until i hard-cycle the power. I unplugged everything, disk drive, HDD, all of it to make sure its not a power issue. Removed the RAM card and modem as well. no dice. I removed a white jumper that was on the motherboard, and thats how I got the zebra stripes to be more pronounced. If i leave the jumper in, I cant see the zebra stripes unless I am looking at it from an extreme angle. (screen too light). No chime.

any ideas?
