after replacing old battery od my notebook, bios complained that there is a problem with battery and linux shows charging, but after hours, there is still 3%. Also, the overal system is somewhat slower, as if the graphics was lagging.
The notebook is Dell Vostro 3550, the new battery is T6 POWER NBDE0120 (9cell, 7800mAh).

Edit:
There is one thing - when I power on the notebook, there is this message: http://www.laptop-junction.com/toast/content/dell-ac-power-adapter-not-recognized
But I have the same charger as with the previous battery. I was assuming, that previous battery is dead due to the yellow blinking power indicator on notebook, but could it be, that the issue is with the AC charger?
Edit 2:
As the @user1138 suggests, I have tested the notebook with another charger (my is 90W, the other one is 65W) and the result is the same with both bateries: the PSU is OK. But it is still confusing, why the BIOS is showing 0W charger when the new battery is used?
Edit 3: So finally I have managed to get tha battery charging - @user1138 has pointed me the right direction, so big thanks to you @user1138. The problem was however not in the charger itself, but rather in the detection of the charger. What I have done to solve this problem: - reset BIOS settings to the factory defaults - dont know, if this helps, because nothing changed after this step, even after restarting the notebook, but maybe it could be somehow important - when the OS botts up, I have unplugged the charger from the notebook for several seconds, and then plugged it back - after that, it immediately starts to charge the battery and after restart I have checked BIOS that now it sees the charger (90 W) - the unplug / plug needs to be done when the powered on, otherwise the charge is not detected.
