when i updated my dell inspiron n5010 to windows 7 service pack 1 the adapter problem started . Then after some days i reinstalled windows 7 and then again i updated the service pack after a while the ac adapter problem started again so i formated the os and installed the fresh windows 7 which i bought there is no problem even after a week .
so i posted the topic so that people may not buy new adapter for this software problem.
The adapter is completely unrelated to windows service pack 1. Such issues would show up with the hard drive removed while in F2 bios setup on battery status.

bios is untouched even after before SP1 installation and after windows 7 clean installation
Correct. But Bios is all that is required to use the AC Adapter and battery. Windows or Linux or any other software is not related to the ability to charge the battery or not.
you'r right but after uninstalling SP1 there's no such problem in the laptop till today
ok but might be the sp1 is having a bug in power management
Booting into F2 Bios setup Battery Status clearly shows if the Adapter is or isnt working. It is totally and completely unrelated to windows or service pack versions. Uninstalling or Installing a service pack is not related to this whatsoever.
ok i agree but how am i not getting the problem after uninstalling the service pack you got a reason for that
a friend of mine did the same update with vostro he encountered the same problem too
" encountered the same problem "
What problem exactly?
What are the error messages in the event log?
ac adapter type cannot be determined your system will operate slower and battery will not charge please connect a dell 90w AC adapter or higher for best system operation
"ac adapter type cannot be determined" has nothing to do with Windows Service packs.
This message comes from the BIOS. If you have a 90W adapter then your adapter or motherboard is damaged.
This message can be suppressed in bios but is not "fixed" by hiding the message.
yes i know that but i am not getting the message now .I ll take my laptop to a dell service point and do a thorough checkup
Ensure that your BIOS revision is current i.e. at BIOS Revision. The BIOS updates have increased battery support and also support for 130 W adapters thus it is possible your error message will disappear if using the latest version.
