Check if the BIOS setting is set to Legacy S3 sleep
To check if the BIOS setting is set to Legacy S3 sleep, you will need to access the BIOS menu. This can be done by restarting your computer and pressing a specific key or combination of keys during the boot-up process. The key or keys required to access the BIOS menu may vary depending on your computer's manufacturer and model. For example, on a Lenovo laptop, you would typically press the "F2" key to enter the BIOS menu, while on a Dell laptop, you might press "F12". It's recommended that you refer to your device's manual or support page to find out the correct key or key combination for your specific model.
Once you have accessed the BIOS menu, you will need to navigate to the "Power" or "Sleep" settings." The BIOS menu interface can vary, but you should look for sections or tabs related to power management or sleep states. Within these settings, you should see options for different sleep modes or standby states, including S3 sleep.
If you find that S3 sleep is not enabled, you may need to make changes to your BIOS settings. However, modifying BIOS settings can be complex and may have unintended consequences if not done correctly. It is recommended that you research the specific steps required for your device and proceed with caution. In some cases, you may need administrative privileges or a password to make changes to the BIOS settings.
Additionally, it is important to note that the availability of S3 sleep may depend on your hardware and operating system. Some older or less common hardware configurations may not support S3 sleep, even with the correct BIOS settings. Similarly, certain operating systems, such as newer versions of Windows, may have limitations or require specific workarounds to enable S3 sleep. Again, it is advised to consult reliable sources or seek technical support for your specific device to ensure safe and effective modifications to your BIOS settings.

Disable Intel Rapid Start Technology
If your ThinkPad won't wake up from sleep mode, there are a few things you can try. Firstly, check if hybrid sleep is enabled on your laptop, as this may be causing the issue. Hybrid sleep is a power-saving feature that combines sleep and hibernation modes, allowing the system to wake up faster than from hibernation alone and be more resilient to power loss. However, it also uses more power than regular sleep mode. To disable hybrid sleep, increase the sleep time, allow hybrid sleep to turn off, and set hibernate to "Never". Then, press "Apply" and "OK".
If disabling hybrid sleep doesn't work, you may need to disable Intel Rapid Start Technology (iRST). iRST is an energy-saving sleep mode that can cause problems with waking your laptop from sleep. To disable it, follow these steps:
- Power on your ThinkPad.
- As soon as the first logo screen appears, press the F2 key (or the DEL key if you're using a desktop) to enter the BIOS.
- Use the arrow keys to navigate to "Intel Rapid Start Technology" or "iRST".
- Use the arrow keys to select "iRST Support" and press Enter to change it to "Disabled".
- Press F10 to save the changes and restart the system.
Disabling iRST will allow your ThinkPad to wake up from sleep mode without the additional start time and other problems associated with this feature. However, note that the BIOS options to configure iRST may not be available on models with a single large SSD.
If you encounter issues with disabling iRST, be aware that simply removing the Intel RST drivers may not be enough to fully uninstall the program. In some cases, a clean install of the operating system may be necessary to completely remove iRST. Before attempting any uninstall or disable procedures, it is recommended to back up your settings, data, and programs and initialize your boot drive.

Check power management settings
If your ThinkPad fails to wake up from sleep mode, you should check your power management settings.
First, make sure your device is set to the right sleep state. For example, with the BIOS setting set to "Legacy S3 sleep", a ThinkPad may fail to wake from sleep in both Windows and Linux. However, with the BIOS setting changed to "Modern standby", it should work fine.
Next, check the power management setting "Allow this device to wake the computer" is selected for the keyboard, the mouse, and the wireless network adapter (if using a wireless mouse with your laptop). To do this, go to Device Manager > Keyboard > right-click the keyboard driver entry > Properties > Power Management. If the box is not selected, select it and then click OK. Restart the laptop and check. With the mouse, go to Device Manager > Mice and other pointing devices > right-click HID-compliant mouse > Properties > Power Management. If you are using a wireless mouse, go to Device Manager > Network Adapters > right-click the WLAN adapter entry > Properties > Power Management.
You can also try increasing the sleep time and disabling hybrid sleep. Then, choose "Hibernate after" to "Never". Press Apply and hit OK.
If your ThinkPad still won't wake up from sleep, you can try unplugging the internal battery and pressing the power button for around 30 seconds to drain the remaining power from the board. Then, plug in the AC adapter and press the power button as normal. Once the OS boots up, shut down the laptop, plug in the battery, and power it on again.

Unplug the internal battery and drain the remaining power
If your Lenovo ThinkPad laptop is not waking up from sleep mode, there are several steps you can take to fix the issue. One potential solution is to unplug the internal battery and drain the remaining power. Here is a detailed guide on how to do this:
First, disconnect the AC power adapter and all other cables from your ThinkPad. This ensures that the laptop is not connected to any power source during the process. Then, carefully turn your laptop over and examine the bottom cover for a small hole, which is usually located near the centre screw. This is the reset hole. Using a paperclip, insert it into the hole and hold the button down for about 20 seconds. This will disconnect the internal battery and initiate a reset of the power circuit.
It is important to note that you should ensure the laptop is powered off before performing this step. Holding the reset button for 20 seconds will help reset most circuits, including power charging and video settings. Alternatively, you can locate the reset pin on the back of your ThinkPad and hold it for 20-30 seconds to achieve the same result. This method will disable the battery, simulating the effect of disabling it in the setup.
After successfully disconnecting the internal battery, allow the remaining power to drain from the device. This may take some time, so be patient and ensure that the laptop remains unplugged during this process. Once the power has been drained, you can try restarting your ThinkPad as you normally would.
By unplugging the internal battery and draining the remaining power, you can address the issue of your ThinkPad not waking up from sleep mode. This process involves safely disconnecting the battery and resetting the power circuits, which can help resolve any flaws or unusual behaviour your laptop may be exhibiting. Remember to refer to your laptop's manual for specific instructions or variations that may apply to your particular ThinkPad model.
