Question:”I think my Dell XPS 15 have a problem in it’s battery. What happens before was whenever I use it for 15mins the battery meter shows not charging. When I unplug and re-plug the adapter it shows battery charging on the dell xps 15 laptop battery meter but for just few seconds.

Right now I think my problem just got worse. It doesn’t even take 15mins for my laptop to be on that non charging stage. The blue light quickly turns off when I try to connect it to the laptop…

I know that Ill be replacing either my batter or dell laptop AC adapter. I just want to make sure which should I replace”

Answer:”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.

Instructions

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 dell xps 15 battery may refuse to charge if the adapter is faulty. Charge the battery with the laptop turned off.

3.Insert the xps l502x battery into another laptop to test it. If the dell 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 for dell xps l702x 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.”
