Question about Dell Inspiron 640m Notebook
Portable batteries are considered a consumable item because as they are used, there is some degradation to the battery. The average life of a portable battery is 300 to 500 discharge/recharge cycles. After that point, the battery's ability to hold a charge slowly decreases, to where it will only power the system for 10 to 15 minutes even when indicating a full charge.
If this is the Original System Battery, then you will need to get a replacement battery to have the system run for a longer period on battery only.
