What is the most gigs I can get on my Sony Vaio MODEL PCG-9RFL


For a hard drive, you should be able to put in as big a drive as you can find in 2.5inch IDE format (check out Newegg.com).

For RAM, Sony claims a maximum of 1GB (2x512MB) of DDR RAM: http://www.docs.sony.com/release/specs/PCGK23rev2_mksp.pdf

As stated in your post "two year old may have dropped it"
If this is true than the backlight has probably been damaged. The small flourescent tubes that generate light through the LCD display.
