Don, years ago, when I first began using a laptop, I placed it upon a music stand that I re-positioned so the larger surface was flat. It had a 10-pound base which made it fairly stable and it held that laptop just fine. I sat it off to one side of the keyboard, mainly so I could glance at it to see lyric files without taking my eyes off the audience.
Worked for me,
Gary
