I didn't expect that it would be less than half a year，now the boot screen appears as above. I tried to contact their technical support department，but there is no direct contact at all. I sent them an Email. After waiting for three days, there was no reply. I didn't expect the quality of this product to be so poor, and I didn't expect their tech support to be this bad either.Today is already January 8, 2023, and the computer has been broken for 8 days, and their technical support department has no solution.
