I have nokia 5310 mobile in my mobile my volume slider button is not working so i can't increase my volume the audio is so tiny.

If resetting it via the power button and thus returning it to factory defaults does not work, you may be looking at a problem requiring a technical repair, such as replacing the IC board. https://repair-mobiles.com/tag/5310/

But I'd first confirm it has taken a full charge.

What type of laptop HP , ASUS , COMPAQ , ACER ?..........
Up the Volume on My HP Laptop
Open the "Start" menu and click on the "Control Panel" icon.
Locate and open the icon that deals with sound.
Depending on your version of Windows, it will say either "Sounds and Audio Devices" or "Adjust System Volume."
Adjust the volume under the "Speakers" icon.
To do this, click on the slider bar and move it up on the slider.
If you need to decrease the volume, simply move the slider bar down.
Click on "OK" when finished and close the "Control Panel" window.
Click on the speaker icon in the bottom-right corner of the screen for a faster volume adjustment. Simply move the slider bar up to increase the volume and move it back down to decrease the volume.

Volume on an Acer Laptop
Acer laptops are typically sold with pre-installed Windows operating systems that offer sound-adjustment features for increasing the volume on the laptop's built-in stereo speakers.
These same functions can also be used in tandem with external speakers or headphones to increase the volume, as well as mute all sound on the laptop.
If the computer should output an unusually low volume, fixing the problem may be no more involved than sliding a control switch with the computer mouse. Click once on the speaker icon in the taskbar on the lower-right corner to open a rectangular window with a slide control.
Click and hold the left mouse button on the slide control to drag it upward, increasing the volume to the laptop's maximum setting.
Click the "Mixer" button below the slider control to open another window with volume controls for "Speakers" and "Applications," adjusting each slide control upward to increase the volume.
Be sure the speaker icon below each control is not accidentally muted.
Click once on each speaker icon to remove the red circle with a slash through it, which will restore audio.
Click the Microsoft flag or "Start" button in the lower-left corner if the shortcut speaker icon is missing from the taskbar.
Click "Control Panel" to select "Adjust Sounds" from the Hardware and Sounds category.

If both the volume does not work there is no other way.The only thing we have to do is to change the Pata(Flex).So, contact mobile repairing shop Or refer the image

Do you have a button on the side off the phone for controlling the volume, or on some phone you can use the button for UP to control the Volume of your phone. While on call press on that button to increase the audio volume.
