the laptop model #psaa0u-01q002 Toshiba is working fine with ac plug. but does not charge my battery and i bought new battery but that one does not charge too.
the light comes on for 5 min. when i plug in the ac power, next to battery symbol in the front. it yellow color. so power is going to the battery, so connection is not the problem but why is it cut it off after 5 min.. and in the power meter it do not show charging too. is there software or hardware issue can anyone help. thank you.

Check this link. Not sure if it applies to your particular situation or not, but worth a go.

Does is cut off at exactly 5 minutes everytime you try to charge it?

try another dc adapter. If that doesn't work, have the laptop serviced.

yes it cut of 41/2 to 5 min..

try another dc adapter. If that doesn't work, have the laptop serviced.
if the dc adapter is bad but the laptop runs fine on the dc adapter. show the green light on the front of the laptop for power.

if the dc adapter is working, then your charging circuit internally needs to be serviced professionally.

hi i did not hear from you about 5 min.. cut off thing let me know. thank you.

I had a similar problem with my toshiba satellite. I had to replace the hard drive and the battery. Was a pain. Call the people!
