Shift key on gateway laptop not working

You can try removing the keyboard from the device manager and restarting the computer.

If that doesn't work then you'll need to swap out the keyboard. Ebay is the cheapest and easiest place to get one ;)

I don't have video on my 400sd4 laptop

If the system is booting up completely and you can hear is starting up then the problem is limited to your video.
First try this
Boot up your system so that it's in windows (listen for start sounds and windows music etc)
once you believe the system is fully booted press and hold the FN key. While holding FN press and release the F3 key one time and then let go of FN. Wait a few second and see if the LCD screen comes on. If it does not try FN-F3 a couple more time, waiting a few second in between.
If that does not work then try plugging in and external monitor to verify that the system is working otherwise. If the external monitor does not come on right away then press Fn-F3 again with it attached to allow the system to send a signal to the external port.
If it works on the external monitor but cannot come on the LCD screen, the that indicates a problen inside your laptop or LCD screen.

Gateway 400SD4 won't power up

replace the battery or have it tested. If these batteries don't have a minimum charge the machine will not boot into windows & will just shut down.You might try checking the battery condition with the "battery conditioner" in the bios

Wont charge past 58%

After you got the new battery did you discharge it completely? meaning used it to the point where there was zero charge. And then charge it. This prolongs battery life. But even if you did not it should still not only charge till 58% so best suggestion while its new send it back.

You should try plugging in an external CRT or LCD monitor. Most laptops will automatically enable this port when you connect a monitor and reboot, but you may need to hit some combination of keys on the laptop if you don't see anything.

You should try this to see if the laptop is running properly other than the internal LCD or VGA hardware.
