OT, but info needed: RAM uprade

Hello everyone... I have a question: I have a Tandy 3800HD laptop that I' trying to upgrade for a friend, with a 486-20 processor, 120 MB HD, 14.4 modem, VGA, and 4 MB RAM. It's a great little computer, but it really can't do much with 4 MB RAM. It has 2 MB on board, and 2 MB in (2) 1 MB 30-pin SIMMS. I have (2) 4 MB 30-pin SIMMS that I tried putting in to put it up to 10 MB. However, when I turn it on, absolutely nothing happens (the screen occasionally lights up). Do I need a some sort of BIOS upgrade, or am I basically stuck with the 4 MB? It currently has Win 3.0 on it, because even with 3.1, it doesn't have enough RAM to do anything.
