(Issue 1): The earliest models of the Touchscreen Tiger used the same motherboard in the country, which has certain issues such as sound card damage, motherboard power failure, and poor contact of motherboard peripheral connectors. Now let’s talk about how to solve the motherboard power failure problem. Once this happens, the screen displays a white screen or black screen, unable to enter the system or see any information. However, when connected to an external screen, it stays on the startup screen. You can distinguish whether it is an old motherboard from the back panel interface, as shown in the following picture:
When encountering this situation, press the Delete key immediately after turning on the power to enter the BIOS settings. At this point, you can only see it through the external screen. Once inside, select the first item to confirm entry.
Then press the up, down, left, and right arrow keys, and select Drive A which should show ‘1.44M,3.5IN’ behind it, then press the ENTER key to change it to NONE.
After changing, press the EXIT key to return to the main menu and change the next item.
Select the third item from the left, as shown:
Confirm entry, then select the second to last item, LCD Type, and change this option to 7. As shown:
After making changes, return to the main menu and select save and exit BIOS settings. The second to last item on the right.
After confirming, a prompt will pop up. If it is Y, press confirm again. If it is N, change it to Y using the single-step save key and then press confirm. After exiting, the console will restart, and then it will display normally.
(Issue 2): Similarly, with this motherboard issue, when setting up the system, some require the use of the WIN PE system. However, when entering the BIOS, both the console panel and external USB keyboard are normal. When entering the PE system selection interface, both the console panel and external USB keyboard fail, making it impossible to select normally. This situation is due to the old motherboard BIOS problem. If we change to an old-style round-headed keyboard, it will work normally. But in reality, such keyboards are nearly extinct, and generally, USB keyboards are used. How to solve this? Enable the USB keyboard support in BIOS settings. The method is as follows:
After entering the BIOS, select the Integrated Peripherals option. Confirm entry.
Then select the second item, Onboard device. Confirm.
In the pop-up window, change the second item, USB Keyboard support, to Enabled.
After making changes, exit and save before exiting BIOS.
Now the USB keyboard will work normally.
