Dell laptop battery maintenance
Regular use of laptop's friends may have a most profound realization is the feeling that a laptop to use a certain stage, the screen will appear dark situation. Like this from happening, maintenance terminology, referred to as "dark screen" is primarily aimed at high-pressure plate can not supply
Acer
batbl50l6 Battery electricity to the lamp on the LCD screen.
The maintenance industry, we have the LCD screen brightness is not enough referred to as "dark screen" means that the ignition coil failed to supply electricity to the lamp on the LCD screen.
Regular use of laptop computers for people who know there is a small LCD screen on the LCD screen lamp for bright, so dark when the screen caused by many people mistakenly believe that is the lamp burned for-1 on OK, and if the LCD screen lamp pipe is so easy to burn, then I think the manufacturer may more complaint letters, where the failure of the screen to make a dark detailed explanations.
First, the dark screen of failure caused by four points:
1, fluorescent tubes disconnected (normal use of the computer will not be destroyed or broken by the high-voltage lamp, lamp off is mainly due to: computer fell to the ground floor lamp strikes the grave)
2, ignition coil no power supply to the lamp (the motherboard with 3-4 group of voltage for the ignition coil, ignition coil through the chip for the transformer to the lamp post, chip to chip, aging or over-current burn without electricity output)
3, motherboard no power supply to the ignition coil (the motherboard there are 3-4 for the group to the ignition coil voltage, motherboards, there are two groups-chip output voltage to high voltage board, chip to chip, aging or over-current burn without electricity output)
4, cable disconnect (between the motherboard and the ignition coil has a cable connected for a long time moving LCD screen cable disconnected, resulting in no main electricity supply to the ignition coil on)
These four points are the major problems caused by the dark Acer as07b72 Battery screen where the points, the first three are more emerged, the fourth point of the opportunities that arise is relatively small, because the connection line is to use a special kind of shield is covered with it and a small number appear to connect line disconnected phenomena. Professional maintenance staff for the detection of each process are essential.
