Battery status
Hi All, I just bought the Dell Studio 1747 and when I charged the battery and was showing as full, I disconnected the power supply and left on the battery.
My problem is that the battery was showing 3 hrs as time left when it is suppose to be over 6 hrs left.
Do I have to leave the battery charging even when it is showing full?
When the Laptop is switched off but the power supply is still connected to the laptop, the battery will still be charging or the laptop has to be switched on.
Thanks,
speedstep

Battery should charge with laptop on or not. However it will take longer to charge with the laptop on.
Batteries in 17 inch laptops do not last 6 hours.
Batteries are only warrantied for 1 year or 300 to 500 cycles.
Over time the amount of time the battery can be run goes down until its dead.
Lithium-ion batteries are limited by their life-spans.
Lithium-ion batteries are also limited by their manufacture date.
The fact is, your lithium-ion battery starts dying the moment it leaves the factory.
You can expect to irreversibly lose 20% of a lithium-ion battery’s charge
every year from its original date of manufacture.
Avoid allowing your device to discharge completely.
If the charge of your lithium ion battery falls too low, the battery can get irreversibly and permanently damaged.
There is an independent circuit that shuts off the device when the charge in the battery is too low.
Another killer of lithium ion batteries other than old-age, would be heat.
