subject: Thinkpad laptop battery from the general solution [print this page] Battery not charging: Battery not charging:
Check the following items:
1, AC adapter, one end is connected to a power outlet on the other end is connected to the Thinkpad on? If not, please correct and continue.
2, the power outlet has power? Some of the socket will be connected to another adapter, or as a separate fuse or disconnect switch to protect itself, lead to socket circuit is broken.
3, do not install the Sony P100 battery through AC adapter can only boot it? If you can not boot, there may be AC adapter or Thinkpad laptop's own fault.
4, the battery is very hot? If the battery is very hot, will not charge. If you feel the battery was very hot, start to remove the notebook, so that its temperature down to room temperature. When the temperature drops down, then install the notebook, and charge it again. If you still can not at this time to its charge, then the need for hardware maintenance services.
With the increased use of time, the battery capacity decline:
Battery capacity is a fully charged battery the system running the length of time the power supply. For all of the batteries, with the growth in use of time, capacity has dropped, were normal. Each time the battery charge and discharge, the battery capacity would have a very small amount of capacity loss.
Through some special power management tools bring back some lost capacity.
You may want to check whether your machine has this specific information, such as certain models in the BIOS upgrade will enhance the power management features. Some models have special tools to improve battery life.

Optimization of nickel-metal hydride (NiMH) batteries to increase their capacity, but the lithium (Li-Ion) batteries do not have any effect. To optimize nickel metal hydride (NiMH) batteries, can be every few months, it conducted the first full discharge (also called depth of discharge) before re-charging operation. Do not Li-Ion battery for the same operation.
Turned off, the Sony P120 battery can not be filled within the standard charge time:
This phenomenon is probably caused by excessive discharge of the battery. By the following steps:
1, off.
2, to ensure that the excessive discharge of the battery inside the notebook.
3, connect an external power supply to the laptop for charging.
If a continuous 24-hour charge, the battery still can not be filled, if conditions permit, please use another piece of the battery test.
If there fast charge (Quick Charger) option, for excessive discharge of the battery for fast charging.
Off and disconnect the external power of the state, the battery discharge phenomenon exists:
If you do not connect an external power supply and the battery placed in the machine, the battery will discharge phenomenon, which is inside the machine need to be very small because the current consumption of the presence of a little power. NiMH batteries will self-discharge as the battery itself, lost a small amount of electricity.
Before the system shut down or, in some operations, the battery status indicator shows empty:
When the battery's actual capacity and display capacity is not the same time, the phenomenon will appear above. To fix this problem, and then discharge the battery charging operation.
Although the battery is fully charged state, but can not boot the system:
This is because the battery inside the force protection may be activated. Turn off the computer, stop a minute to reset the internal protection Sony P150 battery devices, and then re-boot.
