Upgrade paths

RAM

64 MB official; 96 MB via the community RAS2 jumper mod with a Portege 3010 64 MB module (PA2067U) · The official module drops in easily; the 96 MB hack requires soldering a jumper near R2 on the board and is documented across multiple enthusiast sites.

HARD

storage

2.5" IDE drive or CF-to-IDE adapter swap · Community practice rather than an official option; like other Librettos the drive is buried inside the tiny clamshell.

HARD

battery

High-capacity PA2503U 2400 mAh pack · Snap-in replacement, but note it is not compatible with 50CT/70CT batteries.
