Battery power degrades over time, which reduces the portability and function of laptops.

Use this guide to replace the battery in yourAcer Aspire V Nitro VN7-572G laptop.

It is very important to take appropriate precautions if the battery is swollen. This has occurred if the top of the battery is curving, rather than flat, and can be seen as a misshapen keyboard.

Be sure to power down your laptop and unplug from the external charger prior to starting this repair.

  1. Prior to beginning, power off your laptop and unplug from the charger. Flip the laptop over so the bottom is exposed. Use the Phillips #00 screwdriver to remove the two 8 mm screws at the top-left and top-right of the laptop.

Conclusie

To reassemble your device, follow these instructions in reverse order.

Dispose of old Lithium-ion batteries appropriately.

  • Note that the keyboard connector can be difficult to align and reconnect properly. It should be easier with good visibility. It is recommended to insert the connector flat, parallel to the motherboard, rather than in an angled position between the user’s fingers.

If the user wishes to test the keyboard before closing up the device completely, they can connect the laptop to the AC adaptor, which will allow it to power on. Consider using caution.
