Many people keep an old or spare laptop packed away in a cupboard when they no longer need it regularly. It may seem like the safest option—shut the device down, place it inside a bag and forget about it until it is needed again. However, improper long-term storage can gradually affect the laptop's battery and other components.

A laptop does not necessarily become unusable simply because it has remained switched off for several months. The bigger concern is how and where it is stored. Leaving the battery completely discharged, exposing the device to excessive heat or keeping it in a damp environment can increase the possibility of problems.

If you plan to leave a laptop unused for several months, a few precautions can help protect it and make it easier to use again later.

Avoid Storing a Laptop With a Completely Dead Battery

One of the most important things to consider before long-term storage is the battery level.

Modern laptops generally use lithium-ion or lithium-polymer batteries. Even when the laptop is switched off, the battery can gradually lose charge over time.

If the device is stored when its battery is already at or close to 0%, continued self-discharge may push the battery into an extremely low-voltage state. In some cases, this can make it difficult for the battery to recharge normally after a long period.

For extended storage, keeping the battery at a moderate charge level is generally preferable to storing it either completely empty or continuously at 100%.

A charge level of roughly 50-60% is commonly considered suitable for storing a laptop that will not be used for an extended period.

Don't Leave the Laptop Connected to the Charger for Months

Keeping a laptop plugged into a charger throughout long-term storage is also unnecessary.

Battery ageing can be affected by factors including temperature and the amount of time the battery remains at a very high state of charge.

Instead, charge the laptop to an appropriate level, shut it down properly and disconnect the charger before placing the device in storage.

Some laptop manufacturers also provide battery-care or charge-limit features. If your model offers such settings, check the manufacturer's recommendations for long-term storage.

Moisture Can Be More Dangerous Than Dust

A cupboard can protect a laptop from everyday dust, but it is not automatically a safe storage location.

If the cupboard or room is damp, prolonged exposure to moisture may negatively affect electronic components. High humidity can contribute to oxidation or corrosion of connectors and other metallic parts over time.

This is especially important in locations that experience high humidity or where cupboards are positioned against damp walls.

Choose a cool, dry and well-protected location rather than simply placing the laptop wherever there is free storage space.

Heat Can Accelerate Battery Ageing

High temperatures are another major concern for laptops, particularly their batteries.

Avoid storing the computer near a window receiving direct sunlight, inside a vehicle, close to heating equipment or in any location that can become extremely hot.

Prolonged heat exposure can accelerate chemical ageing inside a lithium-ion battery and may also affect other components.

A stable indoor environment with moderate temperatures is generally a better choice for electronics that need to remain unused for a long period.

Shutting Down the Laptop Is Important

If you are storing a laptop for months, make sure it is actually shut down.

Closing the lid does not necessarily switch the computer off. Depending on the settings, the laptop may enter sleep or another low-power state instead.

For long-term storage, perform a complete shutdown so that the system is not unnecessarily consuming power while packed away.

After shutting it down, disconnect the charger, USB devices, external drives, memory cards and other accessories.

Will an SSD or Hard Drive Fail Just Because the Laptop Is Unused?

A common concern is that an SSD or hard disk will automatically become damaged if a laptop remains unused for several months.

That is an oversimplification.

Under normal storage conditions, an SSD or HDD does not automatically become useless merely because the computer has not been switched on for a few months. Storage reliability depends on several factors, including the drive's age and condition, environmental conditions and the length of storage.

However, no storage device should be treated as a permanent or guaranteed backup.

If the laptop contains important photographs, documents, work files or other valuable data, make a separate backup before putting it away.

Back Up Important Files Before Long-Term Storage

Creating a backup should be one of the first steps before storing any computer for a prolonged period.

A laptop can be lost, damaged or develop an unexpected hardware problem regardless of how carefully it is stored. Keeping the only copy of important files on an unused laptop therefore creates unnecessary risk.

Back up essential data to another suitable storage device or a trusted cloud service before shutting down the computer.

For especially valuable data, maintaining more than one copy is preferable.

Check the Laptop Occasionally

Long-term storage does not mean the laptop should be completely forgotten.

If it will remain unused for many months, checking it occasionally can help you identify potential issues early.

Inspect the device for unusual battery swelling, moisture, corrosion, physical damage or other visible problems. You can also check the remaining battery level and recharge it to an appropriate storage level if necessary.

If the laptop's casing or trackpad appears to be lifting or bulging, this can indicate a swollen battery. In such a situation, avoid charging or continuing to use the device until it has been professionally inspected.

Best Way to Store a Laptop for Several Months

Before putting your laptop away, take a backup of important files and charge the battery to approximately 50-60%. Perform a complete shutdown and remove connected accessories.

Store the computer in a clean, dry location away from direct sunlight, excessive heat and moisture. Avoid cupboards affected by dampness or condensation.

Protecting the laptop from dust is useful, but adequate ventilation and a dry environment are equally important.

After a prolonged period, inspect the laptop and battery before putting the machine back into regular use.

Proper Storage Can Help Extend Your Laptop's Life

Leaving a laptop unused for a few months does not automatically turn it into electronic waste. Problems are more likely when the device is stored under unsuitable conditions or when the battery is neglected for an extended period.

The most important precautions are straightforward: avoid storing it at 0% charge, keep it away from heat and moisture, shut it down completely, back up important data and inspect it periodically.

Following these simple practices can help keep an unused laptop in better condition so that it is ready when you need it again.
