Battery Charger to hel test if it's a bad battery or a bad power jack
I do computer repair. I was wanting to know if they have a device that can charge any laptop battery externally. In my troubleshooting I want to make sure I'm not dealing with a bad power jack that's not charging the battery or not charging it right. I want an external device to determine if I'm just dealing with a bad battery that needs to be replaced.
Is this a good question?
