Hi !
1) Did you ever do something "unusual" on your calc, such as putting Ndless or so ?
2) How exactly acts your calc ? I mean : at which point of the boot does your calc reboot ?

[guru90]

yes i tried to install ndless to read the pdf files. For a period it worked. it going to metallic screen with the clock at center and restart.

Let's try this.

Hold before a restart, and release the keys after the screen turns back on.
This should trigger the diagnostics menu which may report a GPIO error. In this case, press to fix it.

Once at the diags main menu, just press the reset button on the back.

most of the tests failed especially: tochpad keyboard adc calibration and others.

Don't bother about them.

Just restart and check if the problem is solved.

it's the same.... boot loop

[critor]

Ok, strange.

Try holding before reaching the metallic screen then.
Does it change something ?

[guru90]

if i hold esc the hands of the clock do not turn and then it disappears and restarts

Then try to remove the OS from the maintenance menu.
Hold before a reset.
