Advice 2: How to save laptop battery
The laptop is a faithful assistant in school, work and social applications. But one of the most vulnerable places in any laptop is its battery, of the correct operation of which depends on the service life of the portable computer.
To get started with a laptop should not be operated at the minimum charge, which there was in the battery when you purchase. The battery charge fully and only after that to start operation. In order to make the battery last longer, you need to select the right power scheme. For this, you need to choose the mode with maximum energy efficiency and to set sleep mode.
The battery life may effect proper installation of the laptop. It should stand on a flat, firm surface, away from heaters, access to the ventilation holes must be free. This will help to reduce the energy costs of various engines cooling system. The lower the room air, the longer will remain the battery life.
Also helps save battery power and disabling unnecessary modules and applications that are not used in the Wi-Fi. It should be remembered that a significant contribution to the load of the computer making the USB device, the number of which should be reduced to the necessary minimum.
Without a doubt one of the main elements of energy consumption of the laptop is the monitor matrix. To save battery power, you should set the monitor to minimum brightness. Also helps conserve and reduce the volume level of the speakers.
A reduction operation of the optical drive also the most effective impact on battery saver, as the existing motor is active consumer of electricity. In order to remove the load from the optical drive, make sure that there were no drives that are not used in the work.
It should be remembered that the duration of the battery life of the laptop depends on the number of charge cycles of the battery. When you connect to the network, charging the battery automatically, so if the operation of the laptop being in the workplace with a constant connection to the network, the rechargeable battery should be removed.
Advice 3: How to revive a laptop battery
Most batteries of modern notebooks lend themselves to good recovery. Sometimes it is enough just to install the necessary program or use the built-in function mobile computer. But most often need mechanical intervention into the structure of the battery.
You will need
- - screwdriver;
- - multimeter;
- - the cyan-acrylate glue.
First, determine the type of battery used in your laptop. Usually it is a Nickel metal hydride (older models) or lithium-ion (relatively new) items. To do this, visit the website of the manufacturer of the mobile computer. Sometimes it contains information about the methods of recovery of the battery by using the utility built into the BIOS.
If to revive the battery using the program is impossible, remove the battery from the laptop previously unplugging it from the mains. Disassemble the battery and remove all items from the unit.
When working with Nickel metal hydride batteries using these steps. Separate from each other all the batteries. There may be more than ten pieces. Prepare a few light bulbs. It is better to use a car bulb (21 watts). Solder the wires to them and connect one lamp to each battery. Leave the device for about 10 hours. It is necessary to completely discharge the batteries.
Now load all the elements. You can use the power supply of the mobile computer and the aforementioned lamp. Connect the bulb to the batteries in series and connect the battery with the charging block of a laptop. Repeat the cycle of discharge and charge elements 2 more times. After that, collect the battery and connect it to the laptop.
When working with lithium-ion batteries, you will need the cyan-acrylate glue. Without it you will not be able to connect the elements after recovery. Be sure to fully discharge the battery. Remove all batteries from the case and carefully detach the interconnected units. They usually consist of two or three batteries. To do this you have to unsolder the metal plate connecting the battery.
Measure the voltage of each element. If it is significantly below 3.7 V, the unit will need to be replaced. Using 5-Watt lamps lower the voltage of each cell up to 3.1 V. This same procedure be done with new batteries. Assemble the battery, insert it into the laptop and connect the charger.
