How come my laptop battery dies out a lot and take forever to charge up?
I just bought new battery and it's my 3rd time buying my ac adapter. my ac adapter always get extremly hot and when my laptop battery is going low it take about 2 hours to charge it back up to 100%. Usually it takes less thant 40 minute to charge it back to full charge. Anyone knows what's wonrg. Sometimes my air vent on the bottom of my laptop get hot too even though I do not cover it up too.

help me!!!

Obama is what's wrong! Can't you see? He is taking all the power from your charger, and your battery, and giving it to those who refuse to plug in their laptops.

Ok, seriously. Check the voltage out of the charger to ensure that it is not low. If it is fine, then either it is the battery, or the circuitry from the charging port to the battery on the laptop.

It's suffering from your spamming.

Because its being discharged faster than it can be charged. Also stop trying to use a laptop as a substitute for a desktop.

Default Wrong Charger...Wrong Duty Cycle...Overheating

They now call them notebooks rather than laptops for a good engineering reason. Seems the computer would overheat if always operating on ones lap. Poor air circulation.

You charger may not be compatable with the battery. The charger should only get warm and not hot. New notebooks send a signal to the charger. If the charger doesn't

Recognize the encoded signal, you may (may) have a condition where for some reason the voltage and amperage profile is not exactly correct for the battery. is a brilliant engineering and marketing solution to make people purchase and employ the factory charger only and nobodys aftermarket version. Yep.

The solution is to let your notebook breathe. Set it on a rack that lets air circulate under. Use only the factory authorized charger. Run the battery down 100% before recharging.

The battery does NOT like being run down slightly, then either sitting for a long time or being slightly discharged, then being completely recharged. They need to exercise.

Hope this helps. HB of CJ (old coot) (batteries LOVE PORN)

It could be a lot of things. Some of which have not been mentioned.

One of my laptops had batteries die quickly because the mother board had problems.

Another one of my laptops had batteries die because the basic software was messed up.

You may have too many operating systems running at the same time.

Not sure why you didn't list what kind of laptop you have. Certain models, specifically HP Pavilion laptops have overheating issues. Google it dude.
