No access in 2nd hand Aspira A314-21notebook, the pin code doesn't work given by seller.

Ouma

Hi. I bought a 2nd hand Aspira A314-21. It starts up with the HDDO and a password. Then it proceeds to Windows where I have to insert the pin code. The seller gave me a code, but it doesn't work. Then I tried F2 to install a new Windows by USB, but the notebook again starts up with the HDDO. It's a loop I'm in and as long as I can't get into the bios, I'm not able to change the booting order. The seller insists that the pin code is right. I also tried the Windows troubleshooter, but it has no system repair. Thank you for a solution.

We can't advice on password issues, bring the laptop to Acer Services in your country to reset BIOS but Acer may ask for prove of purchase (Official receipt issued by the Acer retailer, ask the seller for the original Acer bill).
