I have a good unit, no scratches on screen, barely user keyboard, good battery.But windows set up in VERY UNSAFE way.DO NOT use computer as-is after power-up. Need some work, and ALL is mandatory.Mine have "DELL" admin user, without any password.This is HUGE red flag, immediately.DO NOT connect to internet. Create new admin user with password (MANDATORY), login as that new user, DELETE default "DELL" user. Try to find offline antivirus installer, install it. Run full scan. Enable internet, update antivirus and scan again. If antivirus find anything suspicious, remove it, and immediately change your WIFI password (most likely it will be credential stealer).Mine got a malware (stealer of credentials with remote desktop functionality), so perfect trap for inexperienced user to go online banking and..GRANTED, it MIGHT be a false positive from antivirus. But it might be something already existed or outside attack, and admin account without password is a perfect recipient, without any immunity. This external attack will be initiated and done even before you can download and install antivirus.If you have a knowledge, do it yourself or ask reliable IT person or reliable computer fix service to do fresh windows install with full drive wipe out. You must ask them to create new user for you (with a password!) and install antivirus. Make sure ask them to install same windows version, new windows 11 might not have correct drivers for this computer. You can decide it later.It's 2023 and if you plan to use it for anything remotely serious, even "just email and facebook", you SHALL do a full wipe out, reinstall new system, with antivirus and never allow to create user without a password.Again, VERY GOOD hardware, BAD initial setup.
