After you power up a laptop, it runs a Power-On Self-Test (POST) sequence from its BIOS that checks all hardware devices. Only after determining that there are no issues with those components does your computer boot into the Operating System (OS).
However, if some components are not functioning properly, your laptop beeps in a certain sequence, depending on the components. So, POST beeps are entirely hardware errors, and you need to troubleshoot these components to be able to use your laptop.
How to Fix Laptop Beeping on Startup?
Some startup beeps, like missing CMOS, still allow you to boot into your OS even if you get a POST beep. Your screen should tell you to press a certain key or automatically load the OS after some time.
If the beeps continue, you need to listen carefully to figure out the sequence. Then, look for what the particular sequence represents on your laptop manufacturer’s website. After that, you need to go through the relevant solutions below to resolve your issue.
you may also apply them one by one in case you can’t find any information on the official sources.
Power Cycle Your Laptop
Sometimes, the hardware issues responsible for the laptop beeping may be temporary, such as the devices being stuck after a power failure. you may resolve these issues by power cycling your laptop and draining any residual charge from the capacitors inside the laptop. Here’s what you need to do:
Then, power up your PC and see if your laptop beeps on startup.
Check for Keyboard Issues
One of the most common reasons for the issue is short-circuiting in thelaptop’s keyboard. You need to replace the keyboard altogether to resolve the issue. The process to verify if the keyboard is the cause, as well as to replace it, requires you to remove this device. So, if you are not confident in being able to do it yourself, it’s better to seek help from hardware experts.
Also, if your laptop does not have a separate keyboard strip (there is no separation or seam between the keyboard and the laptop case), it is more difficult to replace. You may need to remove all internal hardware components, so we recommend getting help from the experts.
Here, we only include the steps to check and replace the removable keyboard.
Check Internal Components
Many POST errors and beeps happen because of short-circuiting or other issues with any of your hardware components. So, if you may’t narrow down the reason based on the beep sequence, you need to check all your devices one by one to determine which one is the culprit. To do so,
