This Presario C769US OS Win7 Home 32 bit works just fine except for 1 game that I play a lot away from home. Like if I have a few hours to kill before a meeting starts. This older games are simple to play using just the keyboard. So I don't have to lug around cd/dvd's, joysticks and manuals.
1 game Bio Menace requires certain keyboard cmd's to be entered during game play in order to turn the cheat menu on. 1st C+A+T then C+O+D > a box opens up and type in 91827 then hit enter. (Here is were the Rollover cmd error starts) I next press and hold J+I+M wait a 1/2 second then press space bar. Then let up all 4 keys at the same time. If timing is correct The cheat menu pops up. I checked the keyboard with a keyboard testing prog. When I press J+I+M everything works fine. But holding J+I+M down and pressing space bar, The space bar just doesn't get seen as been pushed. This is the 2nd laptop that I got. The 1st one an Acer one laptop had the same kind of keyboard problem. Now my primary home computer is a Gateway laptop model MD2614U OS win7 Home 32 bit and that big old Toshiba M60 laptop (before the screen croaked) is the one I carryed in my backpack. Now the Gateway laptop and the Toshiba laptop both could handle the J+I+M then space bar cmd with no problems. Is there any way to fix this rollover problem in the Presario laptop. Or change out the keyboard. The last option would be find an other laptop that can handle 4 to 5 key rollover. But I don't know how to find the right one without taking the keyboard testing prog with me on a usb flash drive and test the keyboard before buying it.

The problem lies in the keyboard membrane layout. The only way around it is to plug in an external keyboard that doesn't have this problem or use a different laptop that doesn't have the issue.
