With a 30GB drive it's pointless trying anything. Waste of time.
You need to upgrade the drive to a larger size if you want to keep going.
It appears you have misinterpreted some of the suggestions (i.e. MS suggesting more space ... NOT by plugging in an external drive). Also the method of removing some programs is fraught, I suspect you've dodge of bullet in borking your whole system by using some of the steps outlined. The disk cleanup function is superficial, at best, and leaves behind more than you realise.
I'd stop tweaking the drive to look for space and look at a larger internal replacement drive if you want to keep this device running. All criticism to Lenovo for releasing/selling a device of this limited capacity. Appalling. Reminds of the days when computer makers tried to reduce costs by selling poorly functioning devices with 1 or 2 GB of RAM.
