Notebook batteries, like any electrochemical system made to receive successive loads have a useful life and then begin to lose their ability and perhaps even not accept a charge. However, the current Li-Ion (Lithium ion) used in the notebook is much better than the old Ni-Cd (Nickel Cadmium) they offer greater autonomy and do not suffer from memory effect, completing an average life of 300 complete charge / discharge. In normal use, following the manufacturer's instructions, that means about three years.
If you find that your battery is taking longer than normal, then it is time to do some tests.
How to check the battery life?
With the battery fully charged, connect the notebook and let it rest (without running any programs) with the screen on and no hibernate until loading is complete, or until you feel it is turned off. Calculate the time and compare it to the manufacturer's manual. You can make partial tests, for example, the backup time burning CDs and DVDs.
If, in conducting these tests actually verified a sharp drop of autonomy is necessary to analyze a few factors:
- The battery may be old: over time, some of the liquid components of the battery can dry out and paste each other, affecting the performance of the device. It is a type of problem should not occur before the year and a half battery life. The solution in this case is changed. Check with the manufacturer is still in the warranty period.
- The security mechanism may not be working correctly: to prevent explosions, the batteries have a safety mechanism that does not let these spend its entire load or they reach full charge. When this device is not working properly, the battery can get a lot less energy than it should and then the notebook can be turned off despite having a significant burden. As a solution, is indicated every 30 cycles of use, make a charge and discharge of the battery. This will cause the battery to "remember" its capacity. It is worth remembering that if the operation takes effect, it is best to change the device, but the chip that performs this type of control costs almost as a new battery.
- The notebook may be experiencing leakage power, short-circuit of small intensity in the hardware will make the energy consumption of your notebook to be higher. To solve this problem, both the diagnosis and repair should be performed by a specialized technician.
- The notebook can be very dirty, the air outlet blocked by a pillow or dust, the team is not ventilated and cooler (small fan positioned at the base of the notebook) does not perform its function. Check the position and area in which you use the notebook, and cleaning it.
