ok lang w/o the laptop battery; we usually remove the battery to reduce the weight (since the battery is busted and the office hasn't gotten around to buying a replacement)

a note about UPSes: the entry level ones tend to conk out pretty fast, something like 1 year plus lang. Medyo unstable talaga ung power sa office, so that may be a contributing factor, pero we had one batch os APC UPSes that conked out -- di lang ung battery, pati ung circuitry tinamaan.
