Ran over it with wheelchair

Shattered about an inch of the upper right hand corner of the screen & one long thin crack across the entire screen. It still turns on & goes to the start page but does not respond to touch at all. Have not tried keyboard was afraid to tip it thinking all its' inners would fall out. Also it will power down to the point the 'power off' popup comes up but again touch doesn't work. It does turn itself off at the designated time, so it seems it's not totaled. The only thing I've done is take out all the tiny screws, I couldn't get the back off easily & didn't want to force it. Any efforts to help are certainly welcome, I truly need it. Thank you
