hi all, i am trying to fix my dell 1735 laptop charging problem. basically it has to be plugged in because the battery is not charging. i have ruled out a dead battery by pressing battery test button and it seems ok. i have read on a few forums that it may be due to charger not talking to the battery due to out of date bios drive. it is running a04 and believe it should be updated to a05. i have tried to do this via dell website but when i try to flash the bios it says ' bios update could not be performed due to valid rom image not found'. i dont know if this is because i upgraded vista to windows 7 a few years ago. any help gladly received as im banging my head against the wall on this one! ta

Laptop Battery not showing Charging

  1. Turn off the computer,
  2. Take the battery out
  3. Take out the power supply
  4. Push the power button down for 30 seconds.
  5. Reconnect power supply
  6. Then the battery.

This is because sometimes the mother board gets static and this clears it and the reason it showed not charging was because it was fully charged.

If the power led is flashing white then 4 orange, it's probably the battery. Can also happen if using a replacement, non-Dell charger.

Do the same again and see if it cures it again and how long it lasts.

If none of the above works, try a new CMOS battery.

I'd be inclined to go to Dell forums with this problem as it seems it is their software (for battery charge) that is at fault.

Personally I'd leave it to Win 7 to monitor but have no idea how to disable Dell's one.
