Login BIOS on a gaming laptop Lenovo IdeaPad Gaming 3 may be needed to change boot priority, update firmware, enable virtualization (VT-x) or reset settings. However, many users encounter difficulties: the system does not respond to the usual keys, the loading screen disappears too quickly, or the laptop does not allow entering the menu at all because Fast Boot. In this article we will look at all current methods entering BIOS for models IdeaPad Gaming 3 15ACH6/15ARH7/16ACH6/17ACH6 (including versions with processors AMD Ryzen 5000/6000/7000 And Intel Core 11/12/13th generations).

Feature Lenovo IdeaPad Gaming 3 - using the firmware InsydeH2O BIOS (less often - AMI BIOS), which behaves differently than the classic versions. For example, on some laptop revisions the key F2 only triggers when fast startup disabled on Windows. And in models with AMD Ryzen Double tap may be required Fn + F2 due to conflict with function buttons. We tested all the methods on real devices and collected instructions that work even if the laptop does not boot or the screen is flickering.

1. Standard method: hot keys when turned on

The most common method is to use hotkeys during the POST test (laptop self-test). On Lenovo IdeaPad Gaming 3 the key is usually responsible for entering the BIOS F2 or Fn + F2, but there are nuances:

  • 🔹 For most models: hold F2 immediately after pressing the power button. Press at intervals 0.5 secondsuntil the logo appears Lenovo.
  • 🔹 If it doesn't work F2: try the combination Fn + F2 (relevant for laptops with AMD Ryzen, where Fn blocks function keys).
  • 🔹 Alternative keys: works on some revisions Del or Esc (after which a menu will appear with a choice Enter Setup).
  • 🔹 For older BIOS versions: if the laptop was released before 2021, it may be required F1 or F12 (the latter leads to Boot Menu, not in the BIOS).

⚠️ Attention: If the laptop turns on with black screen and does not respond to keys, the reason may be Fast Boot on Windows or disabled Legacy Support in BIOS. In this case, use the methods from section 3.

2. How to enter the BIOS if the laptop does not respond to keys

If the standard method does not work, the problem is most often due to one of three reasons:

  1. Enabled Fast Startup on Windows — the system misses the POST test, and the keys do not have time to work.
  2. Activated Secure Boot with key lock (relevant for laptops with Windows 11).
  3. BIOS firmware is damaged - the laptop may turn on, but not give access to the settings.

Solutions for every situation:

Problem Solution Note
Fast Startup included Disable in Control Panel → Power Options → What the Power Buttons Do → Change Unavailable Settings. Reboot required.
Key locks Secure Boot Clamp Shift when rebooting through the Windows menu (see. section 3). Works only if the system boots.
Laptop won't turn on or screen is flickering Reset BIOS via CMOS (remove the battery for 10 minutes) or use disaster recovery (see section 5). Laptop requires disassembly.
Keyboard doesn't work during POST Connect USB keyboard to the port Type-A (not Type-C!) and try again. Valid for models with Intel 12th/13th generation.

💡 Useful advice: If laptop Lenovo IdeaPad Gaming 3 equipped with a frequency display 165 Hz, try connecting an external monitor via HDMI - sometimes the BIOS is displayed only on it due to a conflict with the video adapter drivers.

3. Entering BIOS via Windows 10/11 (without keys)

If the laptop boots into the system, but the keys F2/Del do not work, use the built-in Windows tools. This method works even when enabled Fast Boot:

  1. Open Settings → Update & Security → Recovery.
  2. In the section Special download options click Reboot now.
  3. After reboot select: Diagnostics → Advanced Options → UEFI Firmware Options.
  4. Click Reboot - the laptop will automatically open the BIOS.

⚠️ Attention: On some builds Windows 11 item UEFI Firmware Settings may be missing. In this case:

  • 🔧 Open Command line on behalf of the administrator.
  • 🔧 Enter the command: 
    shutdown /r /fw
  • 🔧 The laptop will reboot directly into the BIOS.
