Troubleshooting Sony VGP-BPS9 battery Problem Powered By Docstoc
					Almost all the laptop batteries are made of li-ion cells. Inside the?Sony VGP BPS9
battery, there is power management IC, which can monitor the usage condition and
record related information of batteries. With the increase of use times or improper use,
the information in power management IC will deviate. Therefore, the battery needs to
be self-corrected for normal use. Put in simple, battery self-correction means a
complete process of battery charging and discharging without interruption. With the
function of power management IC, the battery can be self-corrected to the optimal
state. Generally speaking, a normal laptop battery can undergo 500 charging and
discharging cycles. That is to say, a battery can only be used for 1 to 2 years if we use
it everyday. However, the battery self-correct function can not solve the problems
caused by aging chemical materials.
Suppose you ordered a?sony vgp-bps9 b battery from an online website, but the
battery had the following symptoms. Do you know how to troubleshoot those battery
1. Battery does not charge.

discharging process one more time. If the problem still exists, it's very likely that the
battery is faulty and needs to be repaired.
