6 Frequently Asked Questions about “What if the battery loses power when connected to the power supply ”
Why is my laptop battery not storing charge?
If both are present and the computer fails, this might signify internal power problems. I think your laptop battery is not storing charge any more and behave like a short to your laptop power supply circuit. I have these happened with 3 different laptops - two Dell and my daughter's Acer.
What happens if a laptop battery is left fully charged?
Also, when left fully charged, the lithium ions, intercalated in the negative electrode, cause it that electrode to slowly expand and lose cohesion. For that reason, laptop manufacturers such as Toshiba, Samsung and Sony have added a power mode that limits battery charge to 50% or 80%, if the laptop is used primarily from the AC mains.
What happens if a laptop battery is 100% charged?
As soon as the battery displayed “100% charge”, you yanked out the power cord from the laptop, but forgot to switch off the mains or remove the charger from the wall. What happens then? In such a situation, the charger will still draw a minimal current from the mains and the regulator will maintain a steady supply of 5 V.
Why can't I remove a battery /charger from my computer?
If this doesn't help, you might have a defective battery. However, in normal circumstances, you should be able to remove the battery/charger as long as one or the other is present (a computer only needs one power source, two is helpful in case one fails.) If both are present and the computer fails, this might signify internal power problems.
What happens if a charger is not connected to the main power source?
However, if the charger remains connected to the main power source and is not connected to any 'load' for days on end, the electricity wastage extrapolated over weeks and months and years may be considerable. At the end of the day, however small in magnitude, it's just wasted power – power that you could use to charge your devices many times over.
Why does my laptop keep shutting down?
The battery will be charged fully to 100%, then the computer states that it's running on AC line. After a few days, when the battery level drops below 95%, the charging will begin again until 100%. The shutting down occurs even when th battery is fully charge, and the laptop is on AC line.
