Have been looking at a laptop for my neighour, she was in hospital for a few weeks recently and the laptop was left without mains power, the battery went flat.
Upon reconnecting it to the mains, although the laptop boots into windows normally, neither the keybaord nor laptop work.
Few things i've observed. i can connect a USB mouse and that works fine, i can navigate around the login screen. if i connect a USB keyboard (tried two) they dont work, even simple things like caps / num lock buttons to get lights on the keyboard.
I also observed some keys on the keyboard do function, F12 and F11 do dim and brighten the screen, F9 does turn the screen on and off.
I've tried other buttons such as F6 to re-enable the touchpad, no success, F7 doesnt appear to disable wifi etc.
I've tried removing the battery / mains and rebooting, doesnt work.
I've tried removing both battery and mains and holding the power button down for a couple of minutes, then re-applying power, didnt work
I also tried removing the battery only and holding down the power, also didnt work.
I've tried holding down the F12 key upon powering to see if i can get into the bios, laptop just booted normally.
Are there any other suggestions to get the keyboard enabled?

Welcome to the community forums,
Thanks for sharing those details. Could you try to uninstall the USB driver from the Device Manager? From Device Manger >Universal Serial Bus controllers > Right Click > Uninstall > Restart. Then, try to update the BIOS and Chipset driver from our support site. You may use this link https://pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/lenovo-g-series-laptops/g50-30-note... to download the drivers. Let us know how it goes. Looking forward to any updates.

Thanks for the reply, and apologies for the delay in replying.
I understand the instructions, i just have a challenge, without keyboard i'm unable to log in, so i'm unable to perform any of these tasks.

Thanks for this, I have tried external keyboard, doesn’t work, don’t even get the normal status lights such as num lock etc.
Strangely a usb mouse does work.
How is does the device get switched between laptop and tablet mode, I’ll give this a try..?
