How to onda v820w reset BIOS?

Recommended Posts

OTG cable not working - disabled in the BIOS, to do this, and you need to reset the BIOS. What do you need to short out?
Windows on the PC does not see the tablet, as it connects via USB, and it's disabled.
Tablet ONDA v820w 16GB
Windows 8.1 - came off and needs to be reinstalled. And in the BIOS I can not go, because the touch does not work in the BIOS. Only with the keyboard. And keyboard access is disabled by mistake. To regain access can only zeroing the BIOS. What is actually required.

R u having a Bios issue or Touch issue?

If u on ur V820W u can go to BIOS by hitting at "Esc" button.

However I doubt ur touch issue is related to bios...because I has a "touch" problem for 3 week n only resolved it two days ago. I realise the touch was caused by the incompatible date between the Silead.fw and Silead.sys after I clean install a Window only Tablet (I did away with android).

If this is the issue u face I am more than willing to help u.

      After two weeks. the Onda wouldn't start. Red light is either on or blinking. Power button only turns on the backlight. long press / with vol up/down - no change.
      Is there a physical (pinhole) reset button? I read about it in Gearbest but could not locate any.
      Any idea?
      BTW - what is the DC port for?
      Thank you!
