Laptop Troubleshooting: Battery not charging properly

If your laptop stopped charging like it used to, or it doesn't charge at all, or it charges only after you adjust the position of the AC adapter plug inside the power connector, and that could be due to failed battery.

If your laptop doesn't charge completely at first, try removing the charger from the power socket and plugging it in again. Or totally remove the charger and the battery from the laptop and connect it to electricity without the battery.

If the laptop runs smoothly from the AC adapter, it either has to be the problem of bad battery or failed motherboard.

However, you should try to replace the battery first, to see whether that's where the fault is coming from.

If the battery charges only after you adjust the position of AC adapter tip inside the connector, the most possible problem is failure of DC jack.
