The "password unlocker" may not have been entirely benign. You may have to clean out malware. But try & get the networking going first as that'll make
As you said it has "no LAN settings", I'll assume that the WiFi and wired LAN ports are now missing from device manager. I'm also assuming you have
Windows of some version.
Firstly, just ensure it isn't a hardware switch issue (some laptops have a switch that disables or enables the WiFi). You might have to search around
for it. Other laptops use a function key (hold down the "Fn" key and also, at the same time, press the key with the 'WiFi' symbol - whatever it is).
Allow a few seconds to see if it enables or disables things. Also on some systems there is a pop-up on screen that may take some time to show up.
Failing that, try the following:
Go into device manager and see if anything has an exclamation mark, under the 'network adapters' section. If it does, right click the device and
uninstall it. If you see a check-box, at this stage do not check it. When the device is removed, don't reboot, just right-click another device and
"scan for hardware changes". If all is good, the device should re-appear, hopefully without the exclamation mark.
If this doesn't work, remove the device a second time, but this time select the check box to uninstall the driver software. Then do another scan for
If that still doesn't work, download the drivers on another computer, or via a network cable, from the Lenovo support site, copy them to a flash drive
and reinstall them to your laptop.
Next, try this:
Get the Tweaking.com 'Windows Repair All In One' and follow each step exactly, to the letter. Don't skip any stages (including the malware scan) & do
it from 'safe mode'. To do it right takes a while but should fix your laptop. If it doesn't, then it's time to wipe & reinstall. Back up all your
stuff first (external USB drive helps there) and either install from the builtin factory recovery, or have install media and windows keys on hand.
Hope you get going without all the fuss, though.
