I got a old HP Pavillion 532w running Windows XP. w/ 128 RAM and 1.7

Understandably, it is quite slow.

I didn't know orginally how much RAM I had so I opened it up to look at
the chip. I found that it was 128 and the put it back in and rebooted.

Now the computer will turn on, but the screen acts like it is in
Hibernate mode. Also I cannot get any kind of input w/ the keyboard.

I am a new computer user trying to load Ubuntu on this computer and any
help would be greatly appreciated.
