• Press Ctrl-Standby to sh u t off th e alar m (if it’s en ab led)

• Save RAM Disk (if using RAM Disk feature)

• Power down th e system if you do not need th e com pu ter




3 . 3 . 6 Recharging the Battery PacksA sta n da lone ba ttery char ger option is availab le to char ge notebook ba tterypa cks. The batter y packs m ay also be cha rged in t he n otebook as follows:

1. In s t a l l t he ba t t ery pack (s ) in your compu te r (if no t a lr eady in s t a l led ).

2. Con n e ct th e AC Ad a p te r a s d es cr ib ed in S ec tion 2 .

3 . 3 . 8 Resto ring Miss ing Sys te m FilesWh en you p ower u p th e Notebook, i t au toma tical ly checks for certain k eyfi les th at mu st b e pres ent for n orm al system operat ion. If an y of thes e filesare accidental ly erased, as indicated by error message, insert theWindow s95 Startup d iske t te an d r eboot the system .
