Introduction
If your Acer Chromebook Spin 11 (model R751TN-C5P3) is not turning on properly, is not lasting long enough on a single charge, or is overheating during charging or normal use, then use this guide to replace the battery.
The battery supplies power to your device in such a manner that it can be used without a power cord attached at all times. The battery generally allows the device to run on its own accord for multiple hours at a time, but a faulty battery may hinder this time of use in small increments or even altogether.
Prior to using this guide, ensure that your device has been charged properly, and that the charging cord itself is not the issue at hand. In some cases, a new power cord can solve the issue of a nonfunctioning device. This step is important so that one may determine if the battery itself is truly the issue at hand.
If a faulty battery is indeed the cause of the device malfunctioning, one must remove the back plate from the device using a screwdriver in order to gain access to the battery. The malfunctioning battery must be disconnected from its various connections, and the new one must be put in its place. Click here to view where you can buy a new battery. Be sure to connect the new battery in any ways that the previous one was attached.
Before starting this process, be sure that the device is not currently overheated or hot in any way. Taking apart an overheated device could be dangerous and cause harm to the individual performing this task as the battery will still be hot.
