Boot Error

If Your GrandCare Does Not Boot All The Way

If you receive an error during the boot process and the GrandCare interface never appears, it's likely that your BIOS settings have reverted back to factory original. This can happen when a touchscreen has been without power for a long time. It is especially common on Acer Z3-700 hardware. Follow these steps to fix it.

1. Connect a USB keyboard to the touchscreen.
2. Power on the touchscreen and immediately press the [DEL] key repeatedly until the BIOS configuration screen appears.
3. Configure the BIOS as follows (use the [Arrow] and [ESC] keys to navigate the BIOS pages):

• Under Main, set the “System Date” and “System Time” to Universal Time Coordinated (UTC, see https://www.timeanddate.com/worldclock/timezone/utc).
• Under Advanced > CPU and Chipset Configuration, set "Intel AES-NI" to Enabled. o Under Authentication, set "Secure Boot" to Disabled.
• Under Boot Options, set "Launch CSM" to Always, and "Boot Filter" to Legacy.
• Press [F10] to save & exit the BIOS settings. The system will restart automatically.
