How to improve computer problems by checking the hard disk access lamp

In this article, we will explain how to find computer problems from the hard disk access lamp and how to improve them.

The access lamp is attached to the computer.
By checking the lighting and blinking status of the access lamp, you can know the current status of access to the computer's hard disk.

My computer has slowed down or stopped working! In that case, if you check the access lamp based on the content explained this time, you may be able to improve the problem with your computer.

Role of hard disk access lamp

The hard disk access lamp lights up mainly when reading from or writing to the hard disk.
If the optical drive does not have a lamp, some models may flash the lamp in common when reading or writing to the optical drive.

When using a computer, it may suddenly freeze, causing the mouse pointer to stop moving or applications to run slowly.
At that time, check the access lamp, and if it is lit or blinking, you can see that there is a possibility that the hard disk is being read or written.

Depending on how the access lamp lights up, you may be able to tell that Windows is most likely stopped.

In this way, by checking how the access lamp is moving, you can judge the current state of the computer and think about what kind of problem is occurring.

Where is the hard disk access lamp?

So where is the hard disk access lamp located?
Some computers have different lights on, so some people may find it difficult to tell which one is the access light.
There is probably a mark displayed near the lamp on your computer, but the hard disk access lamp may be drawn as a cylindrical mark.

Also, the location of the access lamp differs depending on the computer.
The following items explain where the access lamp is most often located on laptops and desktop computers.

For laptops

For laptops, the location of the access lamp varies.
Basically, it is usually located on the side of the keyboard.

However, recently, there are an increasing number of laptop computers that do not have access lamps.

For desktop computers

For desktop computers, the access lamp is often located near the power switch.
It may be displayed alongside the power lamp, so please check that area.

Phenomenon where the hard disk access lamp lights up (blinks) frequently

The hard disk access lamp may light up or blink frequently.
In this case, it is possible that heavy processing is being performed or the hard disk is being accessed frequently, so we recommend checking the status using Task Manager.
It also explains what to do when your computer freezes.

Check with task manager

If the hard disk access lamp is frequently lit or flashing, it is possible that some application is continuously accessing the hard disk.

If you can open Task Manager at that time, you can see the status of your PC and the applications that are accessing your hard disk.

You can check which applications are accessing your hard disk by looking at the Disk item in the Processes tab of Task Manager. (Task Manager can be opened by pressing Ctrl+Shift+Esc.)

If you check the task manager and find that an unnecessary application is frequently accessing your hard disk, you may want to consider terminating or deleting the application.

If your computer freezes

My computer suddenly froze! In this case, it is not recommended to suddenly force shut down your computer.

This is because the computer may be reading and writing data to the hard disk behind the scenes. In other words, the access lamp may also continue to be lit or flashing.
If you forcibly turn off the power in this state, in the worst case scenario, Windows may not start due to data inconsistencies.

If possible, try to see if you can shut down from the screen that can be started by pressing Ctrl + Alt + Delete keys.

Also, if that is not possible, it is better to wait until the access lamp has calmed down and then force-quit by pressing and holding the power button.

Reasons why the hard disk access lamp lights up (blinks) frequently

If the hard disk access lamp is lit or blinking frequently, the following may be the cause:

• Computer hardware problems (especially hard disk failure)
• Impact of hard disk access by apps
• Increased access to hard disk due to lack of memory
• Increased access to hard disk due to virus infection
• Increased access to hard disk due to Windows Update

Computer hardware problems (especially hard disk failure)

If the access lamp is blinking frequently, one possible cause is a problem with the computer itself.

In particular, there is a high possibility that there is a problem with the hard disk, and in such cases the access lamp may turn on or blink frequently.

Impact of hard disk access by apps

If the access lamp is lit frequently, the application you are using may be affecting the hard disk.
If the processing of an application is heavy, the situation may be improved by terminating the application.

Additionally, if your computer becomes slow after installing a new application, there may be a problem with the application itself.
In such cases, it would be a good idea to update the application to the latest version or check if a fixed version is available.

In addition to running applications, there are also resident applications that run in the background.
Security software and other such applications fall under the category of resident applications, but if there are too many other unnecessary resident applications, the amount of background processing will increase, placing a heavy load on the hard disk.

Increased access to hard disk due to lack of memory

If the memory capacity is insufficient, hard disk access may increase in order to temporarily save data in memory to the hard disk.

Moving data from memory to the hard disk in this way means writing occurs. In other words, insufficient memory is one of the causes of frequent hard disk access.

Increased access to hard disk due to virus infection

A virus infection may also allow access to your hard disk.

Just because the access lamp is on even though you are not doing anything does not necessarily mean that a virus is the cause, but since cases like this do occur, it is a good idea to strengthen your security.

Impact of Windows Update on hard disk access

When Windows Update is performed, the hard disk may be accessed frequently.

If for some reason there are a lot of updates, such as when you open your computer for the first time in a while, there will be more writing to the hard disk, which may cause the access lamp to turn on or flash frequently.

Solution for the phenomenon where the hard disk access lamp lights up (blinks) frequently

As explained in the previous section, there are various reasons why the hard disk access light is blinking frequently.
So, what should you do when the hard disk access lamp frequently lights up or flashes?

In this article, we have explained some solutions depending on the cause:

• Replace hard disk or replace with SSD
• Pause or uninstall an app
• Adding and expanding memory
• virus removal
• Finish Windows Update

Replace hard disk or replace with SSD

If the access lamp is blinking frequently due to a problem with the hard disk, we recommend replacing the hard disk.

It would be a good idea to replace the hard disk with a new one or replace it with an SSD.

If you know that there is a problem with the hard disk based on the access lamp, etc., it is a good idea to take action before serious data damage occurs.

Pause or uninstall an app

If the access lamp blinks frequently due to an application, you may want to consider temporarily suspending the application or even uninstalling it.

Especially if the application is not only heavy, but also has problems, uninstalling or updating is necessary.

If the access lamp blinks frequently when you launch a particular app, temporarily suspend the application and check to see if any bugs have been reported or if new update data has been distributed. Let's.

Adding and expanding memory

If the access lamp blinks frequently due to insufficient memory, you may want to consider adding or expanding the memory.

You can purchase memory and open your computer to install it.
You can install it yourself or have someone do it for you.
There are several slots and types of memory to install memory, so if you are not sure about it, it is a good idea to ask a professional or consult someone who is familiar with it.

virus removal

Access to the hard disk may increase due to virus infection.

In such cases, please remove the virus.
The problem may be resolved by using antivirus software and removing the virus if it is detected by a virus check.

Finish Windows Update

The access lamp may blink frequently while Windows Update is running, so it is best to wait for Windows Update to finish first.

If the access lamp does not change even after Windows Update has finished, there may be other causes.

Causes and solutions for the problem that the hard disk access lamp does not light up

If the hard disk access lamp does not light up, there are several possible causes as listed below.

• There is a problem with the hard disk
• Poor contact with SATA cable, etc.
• Motherboard malfunction

There is a problem with the hard disk

If the access lamp does not light up, the hard disk may be damaged.

Hard disks can be damaged by strong impacts, so if you remember dropping or bumping your computer, for example, the impact may have caused it to malfunction.

If the power light is on but the access light is not, there is a high possibility that the hard disk is damaged as mentioned above.

If your hard disk becomes damaged, you will need to take measures such as replacing it with a new one.

Poor contact with SATA cable, etc.

If the hard disk access lamp does not light up, there is a possibility that in addition to the above, the cable connecting the hard disk may be loose.

This doesn't happen often if you have never touched the contents of a purchased laptop, but if you have a home-built PC, this may happen, so it is a good idea to check.

Motherboard malfunction

Also, when you start up your computer, you'll probably see a logo, but if that doesn't appear or Windows doesn't start, it means that the BIOS isn't working.

The BIOS boots from the motherboard, so if the BIOS does not start, there may be a problem with the motherboard.

If this happens, first try disconnecting all video cards and other devices connected via USB, and then try to see if it works properly.

If it still does not work properly, check the capacitor (a battery-like component) on the motherboard and check for any abnormalities such as discoloration.

If any abnormalities are found, we recommend replacing the motherboard itself.
