My keyboard will not work or my touchscreen. can't find help

I like jayeff's USB keyboard suggestion and would try that first. Also a USB mouse.

Perhaps you have already done so, since you say you've 'updated' etc.

Are your keyboard and touchscreen currently recognized by your Device Manager? Does it

say they have drivers and are functioning correctly?

Jayeff's device removal and reinstall suggestion is worth trying if you have not.

Have you gone to Lenovo support and let them try to detect and install drivers for your

device?

One weird thing just to try because it sometimes fixes inexplicable problems is to test

for a bad ram stick. I know that sounds unlikely, but it takes little time to test and just might be the culprit.

If you've done all this and things still aren't working, here's one more

last-ditch suggestion (a little hazardous these days in terms of malware):

You could get hold of a driver updating disk or flash drive and run that. I still use a somewhat dated

version of Snappy (thoroughly scanned for malware and not internet connected)

to recognize devices and install obscure drivers, especially when putting in a brand new OS.

Sometimes drivers can be incorrect even if Windows doesn't catch that. (Ebay lists DVDs and flash

drives you can buy preloaded with Snappy drivers, btw.)

If everything is recognized and running the 'right' drivers correctly and things

still aren't working, you may have a hardware problem. But I'd only move onto that

after trying every possible software fix.
