BIOS Damage in Computer – What to Do

The BIOS, or Basic Input Output System, is one of the first and most important programs used by modern computers and laptops. Its tasks include managing all the basic devices of the computer, including controlling the motherboard before the operating system even starts. BIOS failures and damage can lead to many problems with the device – the system will not be able to start if the BIOS is not working properly. What to do in such a situation?

Possible symptoms of BIOS corruption on your computer

Regardless of whether you use a laptop or a desktop computer, the BIOS is essential for the device to work properly. Any damage or failures will make it difficult to start the computer, displaying errors before the operating system even starts. BIOS error messages may vary depending on the hardware, but they are most often visible in the form of:

• no image is displayed (despite the sound of the computer starting up),
• the equipment not turning on at all,
• stopping the start-up at the startup credits stage,
• displaying a black background with a BIOS error,
• audio and visual signals while the computer is starting up and then the equipment is turning off again.

BIOS manages access to computer resources and although it does not play such an important role after the operating system has started, it is crucial at the hardware startup level. Recorded on Flash memory chips, it is read only when its operation is necessary for the computer to work. Some BIOS damage can be reversed and repaired by starting the computer appropriately, but in difficult cases it happens that it is necessary to completely unsolder the memory chip with the BIOS and reprogram it.

Repairing the BIOS on a laptop or computer

The most common causes of BIOS failure are a failed system update, a self-damage to the system or damage by the user, most often found in devices whose users like to tinker with system and hardware settings on their own. Depending on these causes and the effects of BIOS damage, its repair may require a more or less complicated intervention, which not every user will be able to perform on their own. The easiest ones, requiring only the use of the Crisis Bios Recovery procedure, can most often be performed based on instructions available on the Internet. It is not easy, but if the laptop starts and stops on the BIOS error message or when starting the system, there is a chance to restore the hardware. Otherwise, BIOS programming may be necessary.

As part of the BIOS programming service after a failure, the FLASH memory chip with the installed BIOS is removed from the laptop and placed in the programmer in order to install a new, working BIOS appropriate for the given computer or laptop model. After reprogramming the BIOS, it happens that not all computer functions work properly, most often due to the resetting of serial numbers and regional codes saved in the system. In such a case, it is necessary to perform additional installation using the manufacturer’s tools in order to restore the computer to the operation expected by the user.
