This section will try to answer the most often asked questions I get.
My laptop will not charge my battery?
This question gets asked quite often. In an older system the battery may be weak, and the cells have died which would require a new battery.
If your system has a loose jack, this would also cause your battery to power poorly. Simply unplug your battery, and try powering it on on straight DC power. If your power cable does not require handling to power on, your battery is bad or an internal fuse.
If you have a bad 2.5mm jack, I sell wiring harnesses to convert your 2.5mm or 1.65mm jack to a wired 2.5mm that mounts to the case lowering the risk of any future DC jack breaks.
Some systems also have internal ceramic fuses that are 10A, 12A, and 15A that may blow. These fuses are soldered directly to the motherboard.
