Dell computers that run also on batteries and not only on electrical power provided by wall outlets, meaning laptop computers, can encounter many problems generated by these small devices, the batteries. A battery could cause issues to a Dell computer first of all when it is not genuine and if it is not inserted properly into the computer.
Or a battery, even if it original, if it’s made for a Latitude model, will never work on a Dell Mini 10 laptop. The problems will seem to never stop if you use a battery which is not genuine, because this damages the computer in time, making it to have a less powerful performance little by little.
There are some Dell computers which recognize from the first moment a non genuine battery, therefore they run only on electrical power delivered by an outlet. The battery, being unrecognized, remains just a simple piece inside of your computer, which has no function at all.
Other problem that may occur is when the computer does not charge the battery. This problem could be generated by a degrated power cable, AC adapter, a connector from within the computer, an outlet, a conductor or God knows what else. In this situation, you have to take all possible cases and try to solve them. If you use a docking station, disconnect it and then try to charge the battery once again.
You have to take into account that perhaps the battery is already fully charged or partially charged and maybe the processor does not recognize the battery is charged and it is the only one in this equation which “thinks” the battery has remained out of power. In this case, you have a software problem, not a hardware one.
If the battery’ LED indicator is not lit, meaning you have a dead battery, make sure you have the right AC adapter. If it is the adapter you frequently use, the adapter could not be the cause. Then attempt to power on the computer, using only the adapter to see what’s happening.
Plug the power cord into the outlet and into the computer. Press the power button and hold it for about two seconds. In this situation, you have two options. The computer either powers on properly, or it doesn’t. If the computer powers on correctly, reconnect the battery and try again, this time with the battery on. Check the battery LED. The LED indicator shows the battery status.
This one can be as follows: battery is being charged (the happiest situation), battery in trickle charge mode, battery below low battery 1 threshold, battery below low battery 2 threshold, unsupported battery, temporary battery failure and fatal battery failure. Many problems may occur when using batteries, and not only laptop batteries. If you have steel nerves, you could try to solve the problems by yourself (read first the instructions from the Dell Support website), but if you don’t want to do it, go with the computer and with the battery to an authorized Dell dealer and let them bother.11
