Lenovo G455 notebook sound problem Which prawns come in to solve it Thank you very much!

This machine is often incompatible with the sound card, so you have to go to the official website**Official driver, with the official driver, there will be no more incompatible problems There are win7 and XP under your own address is。

**Can't be ordered later? Copy it yourself** Thank you.

Upstairs two correct solution I also g455, the same situation. Go to the official website to find the driver**,Re-open the next sound card driver according to the model of your machine.,Just install it.,It's okay to toss in the future.。

Go to the official website and get a sound card driver, reinstall it, and take a look.

It should be a problem with the sound card driver. Just put Lenovo's drive disk in it and reinstall it should solve the problem. If there is no quality problem, it should not be easy to return.

Send it directly to the after-sales service point, and as soon as you say your problem, they will get it done for you. Much less effort.

Since it's a new purchase, why not seek after-sales service?

The sound is most likely emitted by the following components: cooling fan, optical drive, hard disk 1, the heat dissipation of this computer is not very good, and it uses AMD series CPUs with large heat dissipation, so when the CPU usage reaches a certain value, the cooling fan will be louder.

Recommendation: Equipped with a cooling base.

Do not use it on things like quilts.

Install a "Master Lu" and enable energy-saving settings.

2. Look at your CD-ROM drive, if there is a CD in it, please take it out, otherwise it will read the disc repeatedly, and it will ring from time to time.

3、This book has not been on the market for a long time,The hard disk may not ring too much,If you find that there is a problem with the disk reading speed,Find after-sales to see。

Fan problem It would be nice to change it.

First make sure it's the voice of **.

The main noise is:

1. Optical drive. 2. Power supply.

3. Hard disk. 4. All kinds of fans.

Determine the best way to find a countermeasure The basic thing is to oil up, clean up, replace the parts, and consider it yourself.

You can use test monitoring software to monitor the CPU, hard disk temperature, and fan speed to see if the noise caused by high fan speed caused by high temperature.

The sound card driver does not start, some software causes the sound card driver to not start automatically, you need to start it manually, I have encountered this situation. It is recommended that you install a new driver.

Possible causes:

1. The sound card driver is not installed or has failed, resulting in the sound card not working.

2. The sound-related hardware is damaged and cannot be used anymore.

Solution: 1. Use the driver software to reinstall the sound card driver.

2. Hardware damage can only be sent for repair, do not forcibly dismantle and repair, it is best to find customer service after-sales to solve it.

There was no sound at all, it couldn't be.

There should be a fan sound, or a keyboard sound when typing.

Yours is not in the bag.

The next software to see if there is a problem with the sound card and the sound card driver, and then see if you are muted, there may be a problem with the speaker!!

The solution to the computer is silent: (first look at the small speaker or see if the mute is set in the control panel, if there is a problem with the sound card driver, please ** drive wizard, drive life and other software to install the sound card driver).

1. Press F8 to press F8 to get the advanced option to appear in the release of the power, and select "The latest correct configuration" Enter to repair.

2. The simple way is to use the system's built-in system to restore to the time when there is no fault (or use the restoration software to restore the system).

3. If the fault persists, please reinstall the sound card driver.

Use the system that comes with the system restore method:

The system comes with the system restore: "Start" "Programs" "Accessories" "System Tools" "System Restore", click "Restore my computer to an earlier time", press Next, you will see that the date page has a dark date, that is the restore point, after selection, click Next to restore (win7 restore the system, in the control panel then the device and security sub-option and then the backup and restore sub-option).

**After installation, open the driver wizard, it will automatically detect the hardware information of the computer, after the detection is completed, click the "driver update" button to switch the interface, then click "automatic installation", and then click "start update" in the lower right corner.

Update the sound card driver and try it.

G450This is like this, my classmates and I are also the fan is loud, there is no problem, Lenovo heat dissipation is poor, just understand this problem.

Hello, 1.When the laptop is turned on, the CPU fan will spin faster because there are a lot of things to load. After entering the system, the speed decreases and tends to stabilize.

2.This noise is probably related to the fan, but it is not necessarily the sound of the fan turning. It may be that the tentacles of the fan are not in good contact with this, if you can, try to replace it or go to the after-sales service to check, after all, the newly bought machine, check your own rest assured.

3.If the machine in the back heats up, the fan failure will not be good for the heat dissipation of the machine.

4.In addition, it is recommended that you purchase a set of special radiators for laptops to assist in cooling the heat of the machine. This will prolong the life of the machine and give a great guarantee of comfort. Anyway, the heat of the machine is very bad for the machine.

We hope you find the above reply helpful.

There is a big difference between a series of notebooks and a series of notebooks, and the fan is just one aspect. Laptop heat dissipation is not the same as desktop heat dissipation, the fan speed of this laptop is constantly adjusting, and the speed changes with the data of the temperature sensor to achieve the purpose of heat dissipation. Lenovo's current mainstream laptop temperature control is not very good,So the temperature is relatively high when in use,Naturally, the fan will turn faster,Natural sound will be loud。

If you are a new one, it means that there is no problem with the fan and there is no need to blow soot. When you usually use it, you can pad up the book a little to leave more space for heat dissipation for the chassis, or you can buy a heat sink for this book, but even if you have a heat sink frame, you have to make some pads to pad up the book yourself, so that you can better play the role of the heat sink (this is what I found when I used this book). Usually develop good habits, don't treat the computer as an ordinary tool, but as a friend, take care of it, so that the computer will serve you better.

It has not been firmly fixed for a long time.

Dear Lenovo users, according to your description of the closed situation, you can press F8 to enter safe mode after booting, uninstall the sound card driver and power management deficit imitation software before the pin, restart the computer on the Lenovo official website**Install the sound card driver and power management software, do not use third-party software may cause system instability.

To turn off the hotkey, you can follow the method below:

Boot into the BIOS to see if there is a keyboard item, in which you can switch the FN function key. If not, it is recommended that you check fn+esc to see if there is an indicator on the fn, and you can adjust the function keys.

If there is no indicator light on the FN, restore the BIOS settings, if not, then the factory settings of this machine cannot be changed.

I hope it helps you and I wish you a happy life.
