Sometimes situations arise when a favorite laptop refuses to work without failures and errors. Sometimes this happens through the fault of the user - a lack of knowledge often compensates for the simple curiosity of “what will happen if ...”
Some of the problems that disrupt the laptop can be solved in such a banal way as to remove the BIOS battery or reset the settings. This is done quite simply, the main thing is the utmost attention.
And if the laptop asks you to enter a password every time you turn it on? This is a more complicated case and requires accuracy when carrying out manipulations.
What are some simple ways you can eliminate many of the difficulties when working with a PC? Let's try to figure out what you need to know and what skills to possess.
Therapy: resetting laptop BIOS
Why therapy? Because we will not interfere in the "body" of the laptop, but will achieve the result by regular means. At this stage, the question "how to remove the BIOS battery" does not interest us.
First, turn on the laptop and study the start window. In most cases, attention should be drawn to the bottom of the screen. It is in this area that the manufacturer indicates the names of the keys that allow entering the BIOS on this PC model.
If the instructions from the laptop or desktop computer are preserved, you can refer to the documentation. This information is always printed for inquisitive users.
The most commonly used keys are F2 or Delete, in some cases F10. There is no full compatibility, unfortunately, since all computing devices are different and different company standards are applied.
After clarifying the keys used, to enter the BIOS, you must press them at a certain moment. The signal for manipulation is the appearance of the loading screen. If the operation was successful, a blue screen appears with various menu items and sections. This is what BIOS looks like.
The next step is to look for a tab called Exit. Almost all manufacturers use a single name. The tab is located in the top menu. Go to the section and select the line whose name is Load Setup Defaults, in the next step we look for the line Exit Saving Changes (exit, saving the changes).
If knowledge of the English language does not allow you to get an independent translation, you can use Google Translate on your mobile device.
In the vast majority of possible problems, after carrying out these manipulations, the laptop starts to work properly.
Surgery: reset laptop BIOS if password is required
Why surgery? The situation is more complicated, and therefore surgery - you will have to use the method of a little intervention in the internal device of the computer. A successful result requires accuracy, good lighting and a Phillips screwdriver.
What do the symptoms look like? When you turn on a laptop or a stationary version of the device, a prompt to enter a password is displayed. Downloading the operating system in this case does not even start.
Who's guilty? Most often, this situation occurs when the user independently sets a password on the BIOS. In the modern world, we are surrounded by a huge amount of code information, so forgetting is quite easy. There is another option - a joke from friends or acquaintances who have had access to a computer recently. To exclude such cases, it is recommended to set a password and not share this information with third parties. To save the password, find a reliable place: cloud storage, a file or a note on your mobile device with the subsequent installation of information protection.
And now we give the sequence of actions for a laptop and a stationary PC.
How to remove a BIOS battery from a laptop
With such a problem, you can’t do without removing the back cover of the laptop. Therefore, take all safety measures:
- Disconnect all cords from the device - power, mice, headphones, and more. Without a doubt, remove the flash drive with the modem.
- Remove the battery from the laptop.
- With some luck, it will be enough to remove the cover that covers the RAM and hard drive. But there is a chance that you will have to remove the entire back cover. It all depends on the design features of the device of a particular manufacturer.
- We take out the hard drive and the RAM module.
- Below them there should be contacts with the inscription JCMOS (or a similar, key designation CMOS). With their help, you can reset the BIOS: close them, connect the power supply to the laptop, turn on the laptop for 30 seconds.
- Turn off the device.
Also, jumper jumpers can be installed on the contacts, which must be rearranged to close the necessary contacts. In this case, the sequence of recent actions is preserved.
The lucky ones can get a little luckier - some motherboards have an inconspicuous button or hole in the case. Long enough (4-5 seconds) to keep this button pressed. As improvised materials, you can use a pencil, pen or paper clip.
Putting the laptop in its original state. Turn on the device and go into the BIOS. All settings returned to factory settings, password reset.
Otherwise, we are looking for a place to install the battery and remove it.
How to remove the BIOS battery on a stationary PC
In the case of the "big brother", the sequence of actions is not much different. All devices on the back and front are also turned off. Unscrew one of the side walls of the housing. Inside, all the manipulations are repeated, as in the previous version. But the discharge occurs by removing the battery. To do this, on the motherboard, a round and shiny patch is looked for, which jumps out itself if you carefully pry off a special hook.
Beginners will have a question: “To reset the BIOS password, how much to pull out the battery”? For complete confidence, you can wait 20 minutes, the settings will be reset guaranteed. After that, insert the battery back.
