As you wade through these prompts, expect messages nudging you to “Press enter key to continue”. Keep hitting that Enter key as advised. The software will eventually go full throttle, leading up to a crucial moment where it’ll work its magic and reset your laptop’s BIOS password.

Once the software wraps up, it typically gives you a high-five by signaling its completion. It’s the golden rule to give your computer a reboot at this juncture. After the reboot, double-check if the BIOS or UEFI password has bid its farewell successfully. If the password stubbornly lingers despite your valiant attempt, it might be time to delve into alternative solutions provided below to tackle this password conundrum.

Method #3 – Resting By Removing C-MOS Battery

The heart of your laptop’s inner workings lies in the BIOS/UEFI Chip, storing all those intricate configurations and settings that make your device tick. This chip is delicately soldered onto the motherboard, holding the reins to these crucial settings.

Enter the CMOS Battery, a VIP in this setup. Its main gig involves feeding constant power to the BIOS/UEFI Chip, even when your laptop hits the off switch. This power keeps the BIOS/UEFI on its toes, holding onto vital memories like system date and time setups, boot preferences, and most notably, any password you set up for top-notch security.

Now, if you yank out that CMOS battery or let it take a breather for more than 5 seconds, it’s like pulling the rug from under the BIOS’ feet. The sudden power cut kicks the BIOS/UEFI into reset mode, wiping out all those stored settings—including your prized password—back to square one. It’s basically hitting the reset button, saying adieu to your custom settings, and going back to how things were when your laptop first rolled off the assembly line.

So, Let’s See How To Do That

First things first, before meddling with that CMOS battery, make sure your laptop is snoozing, not just taking a nap – completely powered down, no residual electrical jolts running through its veins. And yeah, unplug that power adaptor to cut off any juice flowing to the laptop.

Now, if your laptop’s battery is a free bird (removable, that is), it’s showtime for some battery handling. Hunt for that latch or grab the manual for the step-by-step on safely unclipping it.

But if your laptop’s playing hide-and-seek with its battery, get ready for a bit of a backstage tour. Crack open the back case – yeah, the whole shebang. Once you’re in, delicately sever that battery’s connection from the motherboard. Heads up: every laptop’s a different beast, so precision’s key here. For those laptops with batteries that stick around permanently, getting to and cutting that battery tie needs a surgeon’s touch to avoid any internal mix-ups.

To track down that CMOS battery, step one’s popping the lid off your laptop’s back panel. That’s where it usually hangs out. But if it’s playing hide-and-seek or hiding under layers, you might need to go full-on detective mode. That means disassembling your laptop to give it a thorough scavenger hunt.

The CMOS battery’s sneaky and can be snugly sitting somewhere on the motherboard. You might need to unscrew some bits or even take the whole thing apart to get eyes on it.

It could be super helpful to check out a laptop disassembly tutorial on YouTube that matches your specific laptop model. Watching one of these tutorials can give you a solid roadmap for taking apart your laptop, making it much clearer where that sneaky CMOS battery is hiding inside your device.

Don’t forget to bring an anti-static wristband into the mix – it’s a must for this journey. Strapping on an anti-static wristband is a top recommendation. This little guy stops static electricity from building up on your body and zapping those delicate electronic parts while you’re getting hands-on with your laptop.

Need an Anti-Static Wrist Strap or Screwdriver Kit?

Anti-static Wrist Strap Starts From: @Amazon US ($5.99), @Amazon UK (£4.99), @Amazon IND (₹99.00), @Walmart US ($6.99), @Newegg ($35.99).

Once you’ve found that CMOS battery, it’s time to bid it adieu for about 5 seconds. You can use a couple of twisters or a screwdriver to loosen the battery chip from its snug spot.

If your CMOS Battery is all soldered up to a wire that eventually plugs into a connector, there’s a smarter way to handle it. Instead of messing directly with the battery, put your focus on disconnecting that connected plug. I’m only saying this because sometimes you might see the CMOS battery right there, but its wire goes all the way to the other side of the motherboard. If you try to yank out the visible battery in these situations, you might accidentally mess things up.

If you find out that your CMOS Battery is directly soldered onto the motherboard, a different game plan is needed. To reset the CMOS settings in this case, you’ll have to do some desoldering and soldering.

Desoldering means skillfully melting and removing the solder that’s holding the battery onto the motherboard. Once the battery’s desoldered, it’s disconnected from the motherboard’s power source, basically hitting the reset button for the CMOS settings. Then, you’ve got to solder the battery back onto the motherboard to get things back on track and let the CMOS do its job properly.

This whole process needs a steady hand and know-how in soldering and desoldering tricks to ensure that the battery gets firmly reattached without wrecking any other parts on the motherboard. Doing this job precisely is super important to avoid causing any damage to the motherboard or the CMOS battery, making sure the CMOS settings reset properly.

Need a Soldering Kit?

Soldering Kit Starts From: @Amazon US ($11.68), @Amazon UK (£9.59), @Amazon IND (₹249.00), @Walmart US ($16.99), @Newegg ($15.99).

This is what a soldered CMOS battery looks like:

Method #4 – Resting By Shorting BIOS Jumper

Another way to potentially reset the BIOS/UEFI is by using the BIOS Jumper on the laptop’s motherboard.

This method involves dealing with a specific jumper or a set of pins on the motherboard to reset the BIOS settings. When you short those BIOS Jumpers with the help of a tweezer or a screwdriver, it basically interrupts the normal operation of the BIOS, making it reset to its default setup.

But here’s the deal: you’ve got to be super careful. Check out the laptop’s documentation or the motherboard manual to pinpoint exactly where that BIOS jumper is hanging out and to learn the correct steps for shorting it. If you mess up with the jumper, there’s a chance you could cause some serious damage to the motherboard or other important components.

So, Let’s See How To Do That

First off, your main job is to find that CMOS jumper, which looks like some soldered bits or contacts on the motherboard. Usually, you’ll spot this jumper hanging around near the RAM slots, and it might have a label like “CMOS” or something hinting at its link to CMOS settings.

You can search online to find the specific part number of your laptop’s motherboard. With this part number, you can then look for the circuit diagram or schematic diagram of that particular motherboard model. This diagram will help you locate the BIOS circuit, which can assist in identifying the relevant tracks or connections.

However, it’s super important to be extremely cautious. Avoid shorting any soldered bits unless you’re completely certain about the correct procedure. Messing up by shorting the wrong connections could potentially wreck the motherboard or other important parts, causing serious issues. So, it’s best to steer clear of messing with the soldered bits unless you have clear and verified instructions from a trustworthy source or professional guidance. It’s always better to play it safe than risk accidentally damaging your laptop’s vital components.

When none of the methods have managed to crack the BIOS password issue, the next move is to get your laptop to a qualified pro. These experts have the skills needed to do advanced stuff like flashing the BIOS or maybe even swapping out the BIOS chip.
