![]() You should also update your system’s drivers. If the screen is working now, which it should unless your graphics card has failed or you have a faulty screen cable or screen, try re-enabling the graphics card. Booting into Safe Modeįirst, boot your system in Safe Mode by holding the Shift + F8 key during startup. Fixing a Graphics Card Disabled in WindowsĪs mentioned, if you disable your graphics card in Windows using the Device Manager or another app, you’ll need to re-enable it by booting into Safe Mode. Tell the staff that you need to reset the BIOS by removing the CMOS battery, and often they will be happy to do it for you while you wait. If you still have issues after performing the steps above, try replacing the CMOS battery with a new one.Īlternatively, another option would be to take it to your local PC repair shop. ![]() Once you have access to the battery, follow the steps above for desktop PCs: remove, drain power, replace, and restart.Īfter you’ve rebooted your machine, your BIOS should be back to normal with a functional screen. The best way to find out how to disassemble your particular machine is to ascertain your laptop’s model number and then use a web search to locate a good tutorial or video. If your laptop does not possess the tray feature (most do not), you will need to disassemble your “portable PC” to reach the battery housing.ĭue to the wide variety of laptop makes and models in existence, it’s impossible to provide a comprehensive guide to taking them all apart. Some models have a small pop-out tray on the chassis to enable easy removal, similar to a DVD tray except much smaller in size-approximately one inch wide. Laptop CMOS Battery Removalįor laptop users, accessing the CMOS battery could prove more challenging. Your BIOS should have already reset itself, re-enabling your internal graphics in the process. Then, reseal your computer’s case and reboot your machine. ![]() Now, reinsert the CMOS battery, ensuring it gets inserted correctly.ĥ. This step should give the CMOS time to reset itself to its defaults.Ĥ. With the CMOS battery removed, press and hold the power button for about 15 seconds to drain any residual power in the motherboard. ![]() Once found, pop the battery out, but you may need to disengage some form of clipping mechanism first.ģ. Once the internal components are accessible, find and remove the CMOS battery, which essentially looks like a large watch battery-usually located in an exposed housing on the motherboard. If you’re unsure how to do this, refer to the manufacturer’s information, but be warned that doing so may void your warranty.Ģ. For desktop PCs, CMOS battery removal is relatively straightforward: ensure your machine is powered down and remove all external cables, then open up the case to reveal the hardware inside.Since this CMOS gets powered by a small battery (CR2032), the second BIOS reset option is to remove it. Option 2: Remove the CMOS Battery on Your Laptop or Desktop PC Instead, the computer goes back to its standard startup settings. None of your files or data get modified or deleted since they get stored on the HDD or SSD. Then, reinsert the plug back in place, or, in the case of a three-pin setup, place it back on the original outer pin.īy removing the plug from the pins, the BIOS basically ‘forgets’ what settings to use at startup and reverts to its defaults. Again, press and hold the power button for at least 20 seconds.Ģ. If your switch includes a third pin, remove it and place it on the opposite outer one like the image above. Remove the plug, then hold the power button for at least 20 seconds to drain residual energy. The switch generally includes two or three pins.ġ. If your board includes a reset switch, it is easier to reset your CMOS and BIOS configuration. However, it may use a button on some motherboards. Most motherboards feature a CMOS reset switch, which disconnects the backup battery’s power to the BIOS-it is a pin-and-plug setup. So, skip ahead if you disabled it from the Windows Device Manager, etc. Note: Resetting your computer’s BIOS only works if the GPU was disabled from BIOS. Fixing a Graphics Card Disabled from BIOS Option 1: Reset the BIOS using a Switch on Your Laptop or Desktop PC The CMOS generally appears in the RTC clock semiconductor, but some motherboards have a separate chip.įor further information on the two, check out the FAQ section. The Complementary Metal Oxide Semiconductor (CMOS) acts as short-term memory, which tells the BIOS what to do every time you start your computer.
