Battery not charging sine re-installed windows 7
Laptop battery problems are quite common among owners of all brands of notebooks. On average, laptop batteries last one to three years. Their exact lifespan depends on several factors, such as how much you use the batteries, the number of charge-discharge cycles and the quality of the batteries. Lithium-ion batteries begin to lose the ability to hold a charge over time. Before you replace a laptop battery, consider that there may be other reasons that the laptop is not working properly. You may be able to recharge the battery instead.
1.Determine if the laptop battery is defective. While less than 1 percent of batteries are defective, the possibility is still there. If the battery is new and only charges some of the way, it may just require a BIOS update to charge fully. New batteries that refuse to charge at all may be defective. Purchase a new laptop battery to replace the defective one.
2. Test the laptop power adapter to see if it's faulty. Run the laptop directly from the laptop power adapter and without the battery. If the laptop does not work with the adapter plugged in, the adapter is dead and you will need to replace it. The laptop battery may refuse to charge if the adapter is faulty. Charge the battery with the laptop turned off.
3. Insert the laptop battery into another laptop to test it. If the laptop battery charges in another laptop, the laptop's motherboard may be bad. Replacing a motherboard in a computer can be very expensive. If the cost to fix the computer is not worth the cost of replacing the motherboard, consider purchasing a new laptop.
4. Reinstall the battery to ensure all connectors latch properly. The latch mechanism that holds the laptop battery should click into place. If the latch does not close, remove the battery and examine the compartment for signs of damage.
5. Troubleshoot the BIOS to determine if there is a hardware problem. Turn on the laptop and immediately enter BIOS setup by holding down the "Del" and "F1" or "F2" keys, depending on the make and model of the laptop. When the BIOS screen appears, see how long it takes for the battery to charge down. If the battery does not last as long as the BIOS setup, a hardware failure may be the problem.I hope you find it very helpful. Best regards.

Yes, they do have somethnig built in to detect if you are using a non-Dell battery, ergo you would not receive messages like "Battery cannot be identified" at boot up, and a warning that the system won't charge the battery. It is simply a ploy to ensure users buy Dell batteries at their inflated price. It's also known as anti-competitive behaviour in the business world.
Just so you know, they incorporate the same system with the power adaptor. If you use a non-Dell one, it will state that it cannot determine the power adaptor type and then let you know that the laptop will run slowly and will not carge your battery. Another way to make sure you behave and buy only Dell spares. Incidentally, with the adaptor it knows if it's a Dell one because Dell use the centre pin of the adaptor jack connector to send a 2.5V ID signal to the laptop. The positive and negative of the 19V supply is on the inside and outside of the metal barrel of the jack plug. Internal pin is solely for ID signal.
I'm afraid the only recourse is to purchase a Dell adaptor if you wish for the battery to charge. I'd recommend a second-hand one from eBay. Try to buy the highest wattage one you can.

Go into the battery properties and check if the battery is charging. If it says it is, then test it, use the battery to see if it really is charging, they will sometimes give a false reading. If it's not charging, then check the power supply with an ohm meter for the proper output. If this all checks good, but the battery isn't charging, then I'm afraid you have a failed power management system on the motherboard. The power management system controls the charging along with other power related aspects of the machine. If the power management system has failed, then unfortunately, you will have to replace the motherboard in order to fix it.

If the battery is 2 years old, then buy a replacement battery, see if it charges. Portable batteries are good for roughly 300 to 500 recharge/discharge cycles before they begin to fail roughly 18 months. Dell warrants the Battery for 1 year, so there is no warranty on the battery. If a replacement battery doesn't charge, then the motherboard will need to be replaced. If under warranty, Dell will fix it, if not, motherboards are $100-150 on Ebay.

If you've replaced the battery with a known good and the battery will not charge, then the motherboard will need to be replaced.
