The female power pin on the motherboard is probably loose and not making connection with the power cord. In that case, you would need to take it to someone that knows how to solder it back onto the board.

Dell m5110 laptop won't charge new battery and ac adapter is not recognized in bios


Try another AC cord/charger with the EXACT same specs as original. Is the battery a genuine Dell battery, if not return it? Some aftermarket laptop batteries don't play well with your computer, the pin-out connections aren't correct and MAY be a fire hazard.

Battery won't charge on dell 1505, using a Tragus adapter.


The battery charger circuit on a Dell portable will not operate using a 3rd party AC adapter. The bios automatically disables the charging circuit if an Dell Branded AC adapter is not recognized by the BIOS

My Dell D 600 will not charge the battery and a message appears at start up that says Ac adapter not recognized What do I need to do to get my computer to charge the battery


If the AC adapter is not recognized by the system, the battery charger circuit is disabled. Things you can check:
  1. In the barrel of the connection to the computer, the small wire in the center is the sensing wire. If bent or broken, then the adapter will need to be replaced.
  2. If the pin is not bent or broken, try a different AC adapter (Any D-Series Dell adapter will work) IF that adapter works, replace the AC adapter.
  3. If a known good/new adapter doesn't resolve, then a motherboard needs replacement.

I had the battery not recognized on boot up. then


the Dell AC adapter has a sensing pin so the bios can determine the wattage of the adapter. If the system cannot ID the adapter, the battery charger circuit is disabled. You'll need a functional DELL ac adapter to get the battery to charge

My lap top turns off *** soon as i remove the power cord.... its like my battery will not take charge at all.. the battery light flashes 2 green and one orange... its a dell 9100


Dell has problems with that motherboard not recognizing the battery or the adapter. If you get error messages about the battery not being correct or recognized, the board has issues.

If this notebook is always plugged in then the battery has shorted and won't hold a charge.

Best option is to try another battery. Another thing, if your system is more than a year old, the battery needs replacing anyway.

If you are going to use this plugged in, get another battery, charge it up and remove it.

It could be one of three things. It could be a bad battery, a bad ac adapter, or the recharging circuitry could be bad. I would try pulling the battery out, and see if the laptop will startup and run strictly off of the ac adapter. If that does not work, you have a bad ac adapter. If that works, and the battery has any charge left, try running it strictly on the battery. If it doesnt work, you have a bad battery. If it does work, the circuitry is bad and you will probably need new motherboard. One other thing you can check is where the ac adapter and battery plug into the laptop, and make sure there is no corrosion that could be causing a short.
