How to increase the volume of the laptop

There is a sound adjustment system in the computer. If you feel that the volume of your laptop is too low, you can adjust it. I will share the adjustment method below. Let’s learn it together.

First open the Control Panel on your computer desktop.

Then click Hardware and Sound.

Then click on Adjust System Volume under Sound.

Then a dialog box will pop up for volume synthesis.

Just slide the slider to adjust the volume of the computer sound.

Of course, you can also click on the sound speaker in the lower right corner of the computer to adjust it.

What are the main reasons for laptop touchpad failure?

1. The touchpad driver may be damaged or accidentally uninstalled by the user.

2. The laptop touchpad is turned off. Some laptops can turn off the touchpad through settings, so if the touchpad is turned off accidentally, it will naturally cause the touchpad to malfunction.

3. Caused by computer virus.

4. The laptop touchpad has a malfunction, such as water ingress, foreign matter inside, etc.

What to do if the laptop power light is off and cannot be turned on

1. Remove the battery on the back of the laptop, connect the computer with only the power adapter, and try to turn it on. If it turns on normally, it is caused by poor battery contact or battery failure.

2. If the computer boots up normally using only the battery and without the power adapter, there may be something wrong with the power adapter or a short circuit in the laptop's power connector.

3. Unplug the power cord, remove the battery, and press and hold the power button for 30 seconds without releasing it. Try to boot the computer. If it boots normally, it is only caused by the abnormality of the motherboard BIOS.

4. Unplug the power cord, remove the battery, open the memory cover, plug in and out the memory, wipe the gold finger part with an eraser, and re-insert it (don't do it upside down).

5. If the above operations cannot solve the problem, it is recommended to send the laptop to a repair center for inspection.
