Experts advise charging laptops to fifty percent before long storage
Technology writers explain how to prepare lithium-ion batteries for extended periods of inactivity.

Backup data and power down devices
Users must back up all data before placing a laptop in storage. This precaution prevents losing valuable files if the machine fails while hibernating. Turn off the machine fully and unplug it from the AC outlet. Storing the device in its original packaging offers added protection against dust and impact.
Manage battery charge and temperature levels
The main reason for maintenance is the lithium-ion battery inside the laptop. These power sources need proper care to keep functioning correctly over time. Store the unit in a temperature-controlled place away from furnaces or radiators. Moisture is also bad, so pick a location that isn't damp or humid.
Check on devices every six months
Ideally, check the laptop and charge the battery back to about 50 percent every six months. This maintenance prevents long-term damage caused by over-discharge while the hardware sits unused. Avoid placing heavy objects on top of the lid or screen during storage. Clean the screen and keyboard before putting the machine away for a significant stretch.
