XPS L702x battery doesn't charge, works fine with the cable

Hi, Sorry if this problem was addressed in the past, but I couldn't find anything. My problem is that battery doesn't charge but otherwise computer works fine plugged in. Battery was changed (bought a brand new original battery), adapter was checked (tried it with the different dell adapter) but nothing. Warranty if long over. Any ideas? Do I need to replace motherboard or cheaper solution (without soldering) could be possible.

 

Well, you've already tried the first two things that we would've recommended:. Test to make sure you don't have a defective battery, and test for a defective charger.

At this point, the remaining possibility is the charging circuits on your motherboard are dead. Your options are:

1) Replace the motherboard on the laptop. This is undesirable, because a new motherboard will probably cost about as much as what the entire laptop is worth at this point.

2) Buy an external battery. Permanently attach that external battery to the laptop (through velcro, tape, a laptop case / sleeve, etc), and use the laptop that way. Also undesirable, because you pretty much destroy the portability of the machine. You might as well just use the machine 100% plugged-in at that point. It's also going to be expensive, because a portable battery can easily cost $60 - $120 USD. You're probably better off taking that money and putting it towards option 3:

3) Buy a new laptop, and sell your existing laptop as-is for parts. Probably the most expensive option. But this option will give you a working laptop, that works when not plugged in to the wall outlet, and also doesn't look like a crappy kludge of a solution.

 

You've just confirmed what I was afraid, but still it's better to check. Anyway, thank you for the help.
