Hello.
Yesterday I bought a 12 'a21m, which has a resolution of 800x600.
The machine seems to have a problem on the screen that is very difficult for me to describe.
The image is fine but it has like a refreshment problem, if you look at it for a while it makes you dizzy.
In the bottom right pop up (see image), if you look at it, it kind of vibrates.
The problem is both in Windows and in the BIOS.
Any suggestion?

Re: A21m screen problem
First thing I'd do is connect an external monitor to see what it does. Doing so wouldn't necessarily rule out the GPU entirely, but it does confirm whether it works fine with the 2nd output or not.
If it looks fine, In your situation I might try to find a complete 14.1" LCD top assembly to upgrade with the higher resolution display while also confirming the LCD panel is good.

Re: A21m screen problem
Hello.
Thanks for answering.
I tried using an external monitor and it works fine.
I found 2 weird things.
1) The machine has warranty labels covering some screws. Both on the machine and on the monitor. Makes me think it was repaired.
2) The charger cable gets hot, quite a bit.
I have to disarm to see if there is anything weird.
