I haven't been using my Inspiron n4010 laptop for a while. Now when i tried to turn it on, its not responding.
So I plugged and the batter indicator bulb first flashed blue once and then red 4 times. It repeats this pattern.
Now when I turned on the switch, dell logo appeared, beeped TWICE, and a screen appears, saying
" WARNING: The battery cannot be identified.
This system will be unable to charge this battery.
Press <F1> to continue..
Press <F2> enter SETUP
Press <F12> to enter Boot Menu "
When I pressed F1 Windows logo showed and then a blue screen with numbers flashed and the system restarted.
I tried removing battery and plugged directly to power. Then the same happened again( Windows logo, blue screen, restart)
What should I do?
