If your sleep/wake button has stopped working, there are a few things you can try. This button, also known as the side or top button, is a fixture of the iPhone and is used to wake or sleep iOS with a quick press. If your iPhone is switched off, you can try restarting it without using the side button by plugging your iPhone into a charger with a lightning cable. If your phone is still under warranty, you can contact Apple Support to see if they can fix the button or replace your device.

Reset BIOS to default settings
Resetting your BIOS to default settings can be a powerful troubleshooting tool when facing hardware issues. The BIOS (Basic Input/Output System) is a type of firmware that acts as an interface between your computer's operating system and hardware. It is usually stored on a chip on the motherboard and contains instructions that tell the computer what to do when it is turned on.
The method to reset the BIOS to default settings varies between different computers and manufacturers. Here is a general step-by-step guide:
- Restart your computer and press the key indicated during startup to access the BIOS setup utility. This key is usually F2, F10, DEL, or ESC.
- Once in the BIOS setup utility, look for an option to "Load defaults" or "Reset to default settings." This may be under a "Restore" or "Recovery" menu.
- Select the option to load the default settings and follow any additional on-screen instructions.
- Save and exit the BIOS setup utility. Your computer will then restart and boot into the operating system with the default BIOS settings.
For Dell computers, the process may involve the following steps:
- Tap the F2 key several times until "Entering Setup" appears.
- Press the F9 key to load the default settings, or press Alt + F keys.
- Press the Esc key and select "Save and Exit" or "Exit."
- Press Enter to save the changes and exit the BIOS setup screen.
Additionally, for desktop computers produced before April 2020, a jumper-based reset method may be required. This involves physically accessing the motherboard and resetting the CMOS battery connected to it.
It is important to note that incorrect settings in the BIOS can cause system instability, so always back up important data before making any changes and consult your device's manual or manufacturer support for specific instructions.

Update BIOS and chipset driver
If your sleep/wake button has stopped working, it could be due to an incorrect Power State setting in the BIOS and Windows, or a corrupted driver. Updating the BIOS and chipset driver is often the first troubleshooting step.
The BIOS (Basic Input/Output System) is software stored on a small memory chip within your computer. It controls how information is exchanged between system devices, such as keyboards, disks, and displays. It also manages data flow between the operating system and attached devices, such as the hard disk, video adapter, keyboard, and mouse.
The chipset driver is the software that controls the various components in your system. It is important to keep these drivers up to date as they can boost your CPU and help your computer run faster and smoother.
There are a few ways to update your BIOS and chipset driver. One way is to use a third-party tool, such as CCleaner, which can check for all your drivers and update outdated ones. This is a safer option than updating manually as it prevents the risk of installing incorrect or incompatible drivers, which could cause your system to break.
If you want to update your chipset driver manually, you can do so by using the Device Manager. Here are the steps to follow:
- Right-click the Start menu and select Device Manager.
- In the Device Manager window, expand the System devices categories and right-click the chipset driver that you want to update.
- Select the "Update driver" option.
- You will then have two options: you can search automatically for updated driver software, or you can update manually.
- If you choose to search automatically, Windows will search for the updated chipset drivers and then you can follow the on-screen prompts to install them.
- If you choose to update manually, you will need to download the correct chipset driver for your Windows system (e.g. Windows 10, 32-bit or 46-bit version) from the official website of your motherboard manufacturer.
- Once you have downloaded the chipset driver, open the downloaded files and follow the on-screen prompts to install them on your computer.
It is important to note that you should always download the chipset drivers directly from the official website of the manufacturer, as those from the manufacturer's website are often outdated.

Check for system problems
If you are unable to wake your computer from sleep mode, it may be experiencing a system problem. Here are some troubleshooting steps you can try to resolve the issue:
Check your keyboard and mouse
Firstly, check that your keyboard and mouse are functioning correctly and are properly connected to your computer. If you are using a mouse and keyboard, ensure they are connected directly to the computer or docking station and not to a USB hub. If you are using a Bluetooth device, note that you may be unable to wake the system using these input devices. Try using a wired mouse or keyboard to wake the computer.
Check your power settings
Open the Control Panel and navigate to "Keyboard" in the Hardware tab. Click on "Properties", then the "Power Management" tab, and verify that the "Allow this device to wake the computer" option is enabled. If you are unable to find this setting, try updating your keyboard driver.
Update your BIOS and chipset driver
An incorrect Power State setting in the BIOS and Windows, or a corrupted driver, could be preventing your computer from waking up. Update your BIOS and chipset driver, and then test your computer to see if the issue is resolved.
Check your network adapter settings
Your computer may be waking up due to network activity. Open the Start menu, search for "Device Manager", and find your Ethernet or Wi-Fi adapter under "Network Adapters". Right-click on it, choose "Properties", and open the "Power Management" tab. Uncheck the "Allow This Device to Wake the Computer" option, or select "Only Allow a Magic Packet to Wake the Computer".
Check your wake timers
Open the Start menu, search for "Edit Power Plan", and click on "Change Advanced Settings" in the Edit Plan Settings window. Head to "Sleep" > "Allow Wake Timers" and change "Battery" and "Plugged In" to "Disabled". Repeat this process for all your power plans.
Run the Windows Power Troubleshooter
The Windows Power Troubleshooter can help you adjust your computer's power settings and identify any issues. Search for and open the Control Panel, then type "Troubleshooting" in the Control Panel Search field. Click on "Troubleshooting", then under "System and Security", click on "Improve Power Usage". Click "Power" to run the Troubleshooting tool.

Check for hardware issues
If your sleep/wake button has stopped working, there are several steps you can take to check for hardware issues.
First, you should check if your computer supports Advanced Configuration and Power Interface (ACPI). ACPI-compliance is necessary to take full advantage of the power management and Plug and Play features in Windows. If your computer is not ACPI-compliant, the only way to wake your computer from sleep mode is to press the power button. If you are unsure whether your computer supports ACPI, you can refer to the printed documentation for your computer or motherboard, or contact the manufacturer.
Next, you should check your keyboard settings. Open the Keyboard control panel item, then click on the Hardware tab, followed by Properties. Click on the Power Management tab and verify that the "Allow this device to wake the computer" option is enabled. Click OK, and then click OK again.
If your keyboard settings are correct, the issue may be with your BIOS settings. The Basic Input/Output System (BIOS) may be reducing power to the port that the input device is connected to. You can try resetting your BIOS to default settings. To do this, power off your device, then press and hold the F2 key on your keyboard. While holding the F2 key, press the power button to turn on the device. Keep holding the F2 key until the BIOS setup screen appears, then release it.
If you are using a Bluetooth device, this may be the reason why your keyboard is unable to wake the system. In some low-power states, the wireless transceiver may be unable to receive information from Bluetooth devices.
If none of the above solutions work, you may have to dig into the wake timers set on your computer. Open the Start menu, search for "Edit Power Plan," and click on Change Advanced Settings in the Edit Plan Settings window. Head to Sleep > Allow Wake Timers and change Battery and Plugged In to Disabled. Repeat this process for all your power plans.
