Basically the problem seems to stem from the fact that the control of the charging current is (apparently) done by the PC itself and it uses the "value" of the battery gauge to determine when it should switch to trickle charge mode. As a result, if the PC doesn't know the state of the battery (if you've just put it in or if the PC hasn't been used for so long that all the batteries are completely flat), then it may allow the "quick charging" to go on for too long (and the battery LED will stay orange). Tony also pointed out that dead or half dead batteries will not charge if you tell the system that the battery is fully charged. Therefore (assuming that all the above assuptions are indeed correct) you should set the battery gauge to a higher value than what you believe the battery to be charged to and let the PC figure out the correct value (as it does when the battery gets low). Hope this helps those who've been sending me mail.. HuiLin limhl@hpsgm2.hp.com
