=== RAM upgradability ===
This model has a single SODIMM socket, which officially supports up to 16GB of RAM (PC4-17066 DDR4 SDRAM 2133MHz SODIMM).

=== Disassembly ===
Any internal component replacement or upgrade (including hard disk and expansion cards) requires opening the back cover. Keyboard replacement requires full assembly and disassembly of the system board, and fresh thermal paste for the CPU heatsink.

Opening the case involves two stages:
* Opening a handful of screws (these have tiny retainer rings made of transparent plastic; be careful not to drop them when removing the back cover).
* Carefully prying apart dozens of little fragile plastic latches. This requires a plastic case opening tool to avoid damage (a metal screwdriver will nick and scratch the plastic).

=== Key mapping ===
This model has a 6-row keyboard, where the {{key|F1}} through {{key|F12}} share the same top-row physical keys with special functions keys (volume, brightness, etc.). By default, the top-row keys invoke the special functions, and require {{key|Fn}} keypress to invoke the usual {{key|F1}} through {{key|F12}} functions. To switch the role and have the top-row keys default to {{key|F1}} through {{key|F12}}, enable Fn-Lock mode (by pressing {{key|Fn}}+{{key|Esc}}).

Problem with checking battery status

2005-11-10T09:03:58Z

Cbm: add another reference

R31 laptops have a problem were checking the battery status causes the mouse to jerk around the screen clicking on things. Also sometimes repeating keypresses are generated.

===Causes===
Apparently a BIOS bug. Seems to happen with both ACPI or APM.

===Workarounds===
Don't query the battery. Remove any battery applets from your panel.

===Undiagnosed problems===
The problem seems to have returned to my system every since I upgraded to GNOME 2.12 and starting running hal/dbus. Perhaps one of those components is querying my battery. If anyway one has any suggestions, please post!

===Related Symptoms===
These messages in dmesg seem to be related:

psmouse.c: TrackPoint at isa0060/serio4/input0 lost synchronization, throwing 2 bytes away.
psmouse.c: TrackPoint at isa0060/serio4/input0 lost synchronization, throwing 2 bytes away.
