Question about Dell Inspiron 1420 Notebook

1 Answer

I have a Dell Inspiron 1420 laptop. I left it running overnight and when I checked in the morning the screen was moving up and down. I tried playing videos in full screen and it does, too. It seems as if the screen was bouncing even though the laptop is still booting up. Please help.

Boot in the safe mode, see if issue still occurs (F8 at boot) if it does, then likely there is a problem with the Video Card or the LCD itself, I'm leaning toward the video card.
Try flashing the bios to current and installing the most current video driver, see if anything changes.

Hello try to renew the display driver from here:

If the driver does not help the screen must be renewed.

This will cost approx 200 dollars.

Good luck

Dell Inspiron 1420 will no longer boot


you need to enter setup by tapping one of the f keys or the delete key. i'm not sure which it is for this model. when you enter the bios setup change the boot order to boot to the dvd first. hit f10 and save the change then reboot with your install disk in the drive. it should start installing.

Left internal spkr not working


Try connecting an external set of speakers or headphones, see if you get both channels, if you do, then the speaker assy is bad and needs replacement.

If you only get audio on 1 channel externally, then check all the sound settings in Control Panel (make sure correct speakers are selected and the playback settings are all correct.)

Sounds like your graphics adapter isn't working correctly or there's a problem with something in Windows (I'm assuming you're running Windows XP). If so, restart your computer and hit F8 until you get a menu. Select Safe Mode and see if it boots up correctly. If it does, note any error messages you may receive and then shut it down. After shutting it down, let it start up on it's own and see if you get your picture back.

Over heating of my DELL INSPIRON 1420


The fan could be faulty (ie stopped spinning) or the heatsing vents are clogged with dust.
Remove the fan and check/clean the vents/fan. If the fan is faulty replace it.
