Asus laptop CMOS battery

Asus laptop CMOS battery

You've been the owner of an Asus laptop for a few years now. Its reliability and perfect strength have enabled you to make it a daily companion, both for your work and for personal use. Its ergonomics and its weight / size ratio have allowed you to use it comfortably, even when on the move.
But for some time your computer has had some malfunctions and after some research you have been told that it was perhaps the battery of the motherboard that was not working
Various symptoms are specific to this failure:
- The date and time of your laptop have to be reset every time you start your pc?
- Do you have problems when you turn on your laptop?
- An error messages appears before each load of the operating system?
- Your user information like the Hardware settings must be reset every time?
- Random dysfunctions appear?

No doubt, your Asus bios battery needs to be changed!
This pile on the motherboard is used to store all your boot information such as hardware configuration and various parameters, it is part of the ROM. Without it, it will no longer save the date, time or settings data.

On average the lithium bios battery must be changed every 5 years, like any battery it has a limited life due to its natural wear.

Accessoires Asus offers bios batteries of the motherboard compatible with your model of Asus laptops (VivoBook, ROG, Netbook, Chromebook, ZenBook, VivoBook).
Rest assured that the quality and durability of our new, 100% original, replacement batteries are Asus certified.
You will be able to change the bios battery of your PC Asus, always sold with its connector, to find all its basic functionality essential to its fluidity of use.

We often recommend that our customers do their repairs but changing the bios battery is a complex and delicate step and requires good experience and technical knowledge. We do not advise you to do it yourself, it would be better to call an expert rather than risk damaging other parts of your laptop if you have to manipulate the motherboard or carry out a micro-welding.
