Windows laptop does not boot without Battery

Windows laptops may or may not work without a battery, depending on the OEM. Some users have reported that the laptop does not boot without a battery when they take out the battery and try to run directly on power. In this post, we will share how you can fix that.

Windows laptop does not boot without Battery

1] Check BIOS/UEFI settings

One key reason your laptop might not boot up without a battery is the power settings in the BIOS or UEFI. So, make sure that power-related settings are correctly configured in the BIOS/UEFI.

 

• First, reboot your computer using the battery. While booting, keep pressing keys like DEL, ESC, F12, etc., to enter the BIOS/UEFI.
• From BIOS/UEFI mode, look for options related to power and enable any option related to power on without a battery.
• Once done, exit the UEFI and boot up your laptop without the battery to see if it works.

2] Check if your laptop is charging

Another reason could be that your power adapter jack is faulty. As a result, your laptop isn’t booting up without a battery. To inspect this, you can simply boot up your laptop with the battery and keep it plugged in.

It works fine if your laptop’s battery is charging or showing a power adapter icon. Otherwise, you will need professional technical help.

3] Power Supply Issues

The issue could also be with the adapter. If you have a different power adapter with you, use it to test if your laptop is charging or booting without the battery. If it’s booting up, you will have to replace your power adapter. In case your laptop doesn’t turn on or boot up without the battery, you need to seek professional technical support.

I hope this helps.

Disadvantages of using the laptop without a battery

Laptop users are always confused about whether they should use a battery only when they don’t have access to power or if they should always run on power or keep running it without the battery.

Here, we discuss the problems you could face when using a laptop without a battery.

• No stability: The laptop’s battery helps regulate power, so your laptop can run uninterrupted during power interruptions or fluctuations. By removing the battery, you can expect sudden shutdowns or unexpected restarts due to power instability.
• Reduced portability: Without a battery, your laptop becomes like a desktop. You will always need a power adapter to run it, and you won’t be able to use it when you don’t have access to a power outlet.
• Limited system performance: Without a battery, your laptop may not perform at its best. Certain laptop components, like the CPU or GPU, may throttle performance to save power when running without a battery, which could affect performance.

Can you run a laptop without battery?

Most modern laptops run without a battery if they are connected to a power outlet using a compatible or original AC adapter. However, there can be some exceptions if the OEM sets the configuration. This is specifically true for old-generation laptops. 

If you’re uncertain, you can check your laptop’s manual or test it by removing the battery and plugging it into the wall outlet.
