Compaq Armada 7800 will not start with battery
I have a Compaq Armada 7800. With the power cord connected the laptop runs fine and power management reports only 3% of the battery is full and that it is still charging when in fact its not. I have a new battery and external charger so I know the battery is good and fully charged, also the laptop will charge the battery with no problem too. Its when I try to power up the laptop with the just the battery, the laptop will boot and I see the Compaq screen then the laptop will shut off and will not power up again until I remove the battery and slide it back in the laptop will power up again and shut off everytime at the Compaq screen. I have tried both bays with the new battery just to get the same end result. Is the problem in the system board or could it be the power supply. Thanks for any help... |
One would think my only solution for any PC problem is reset the CMOS or
replace its battery. I don't know about the 7800 but some older Compaq laptops would not boot if the CMOS battery was dead unless connected to A/C adaptor. Might replace that CMOS battery.... Dale |
A few questions first :
You said that you have " have a new battery and external charger " : did you 1. have this problem and 2. bought the new battery and external charger to fix it ? If so, prior to this , did it also charge to 3% ? My reason for asking is that I worked for Compaq for years and it was common for a lot of the batteries to " appear fully charged" meaning that the customer would press the button on the battery and the indicators would indicate that it was fully charged, when it really was a bad battery and would not accept a charge. There's 2 "parts of the battery" the "charging part" and the "reservoir part". Sounds like your charging section is dead. OR the chemicals in there won't hold a charge (too old) = same result = NG to you. . If it's something you bought "new" , have them send you another. There were a LOT of problems with batteries for the 7400,7800,m700 etc - all the same vintage. Often it would prevent the PC from powering up - it would pull down the voltage of the laptop. you pop out the battery, power up and then reinsert and it was OK - but it wouldn't charge. bobb "Damien" wrote in message rthlink.net...

I have tried 3 new batteries with the same result, the laptop will charge the battery for around an hour and half and then the charge light goes off, with the external charger I charged one of the batteries and the same thing happens every time laptop will boot to the compaq logo and then shut down. And all 3 batteries reported 3% full and charging in Power Management but there is no charging happening and all 3 batteries reported they were full by pushing the button on them.

Thanks everyone 4 replying. I have the problem fixed now. It was a BIOS
thing, after flashing it to the newest version all is well now. I am glad it was just that I wasn't looking forward to opening this thing up and replacing the MB. Thanks again 4 all the help...
