Dear Representatives, The problem with my laptop is the battery. You may think it is not related to softwares but it is. You see, I'm a electronic technician myself and I recently had cracked up an old Li-ion battery of my laptop and replace new cells in it to save me from buying an expansive new battery =). (I used different brand of cells to replace the old one, but the capacity is the same.) Anyways, the laptop or the charger seems to "remember" the capacity of the old battery and does not recongonize my new battery. As a result, when it "fully" charged up my new battery, well... it just reminds me of the old junk -- no more then 30 minutes of use time. On the other hand, when I use another charger (those one for radio control cars) I can truely charge up the battery, the result using time is approx. 2 and half hours. So I'm confirm it is not my battery's fault, it is the charger or the laptop's "memory" that is massing around. I was wondering is there anyway to change/erase/elminate those "memories"? Any help would be appreciated. Thank you! Ray

Thats an interesting question you pose. Maybe their is some conspiracy between the laptop makers to degrade battery charge life over time. That would explain why a lot of people have to buy new batteries every year, just after the warranty expires.

Check the voltage when the battery is charged using the the computer charger. The voltage is probably the same every time within probably 0.002 v. When charging with the RC charger the voltage is probably much higher, probaby by about 0.1 v. The cause is the your new cells is not quite the same as the old cells. I don't know if you can adjust the voltage regulator in your computer. Otherwise just use the RC charger.

Speaking of this conspiracy thing, I have always had the suspicion that the main speed bottleneck in computers is wait states called for in the software. All batteries have become more expendable in the last 20 or 30 years. This occurred about the same time as the explanation of memories in batteries. When drv cell non maintenance batteries came on the scene some of them work and some do not. One of two batteries for a camcorder went bad within a year. The other one has worked fine to this day. The same thing has been true of car batteries. However, none of my electric drill batteries holds enough charge although they have not quit completely. Your laptop is an interesting problem. In case you are on to something please post back if you discover why one charger will charge the battery and the other one will not. Voltage as an explanation is a possibility but it would take a large voltage difference to explain the phenomenon. What else could it be though?
