    sure...i'd suggest you check it's warranty status, and then arrange for a service call, with either an lcd replacement or motherboard swap..

I had that problem not half an hour ago. I resolved it by swapping my 2 ram chips around and it seems to ok thus far. It's worth noting I installed another 512mb a week or so ago. It has run beautifully till this afternoon. I tried using ac and battery, ac and no battery and battery only. With no result.

Hi my son got some sort of virus and i cant get onto the internet or it wont let me go back to any set points its just blank its a dell 6400

Hi there,

Which is the Anti-virus you have in your computer?
Since when are you not able to go on-line?

Follow the steps below:

1) Restart the computer and start tapping F8 key on your keyboard before the windows logo come up.

2) You would see a Black screen which says Advanced Boot menu or options,select Safe mode with networking with the help of up and down arrow keys.

3) Clcik yes on the Pop up which appears once you enter the safe mode.

4) Run the Malware bytes to get rid of the malwares.

5) Run the ccleaner to take off all the Junk from the computer.

6) If you dont have a Anti-virus in your computer then Download it.

7) Reset the browser.

Post back if it is not working we will be happy to help you.
Hope this helps.

Dell inspiron 6400 errors 0244 and 1A44

Sounds like a bad drive but it may still have the data on it (hand it over to a professional).
Next time, don't forget to do your backups so you don't have to worry.

Dell inspiron 6400 screen won't go 'full screen' on pinball (running XP Pro)

Hi Dominic
You need to buy a new computer, a Mac ideally.
A possible work-around for the 'not going full screen' problem would be to sit much closer to the screen, making the images appear larger.
If you could get hold of a magnifying glass from ebay this may help too.

Screen wont turn on , i have a inspiron 6400 .. I rang dell & my extra 3yr warranty ran out just 6 weeks ago & * They WONT HELP*

when you say screen will not turn on it means we do not have display right? now, try this. turn off laptop, press and hold D key then press power button, check if the LCD will display colors if yes then it might be your video card causes the problem which needs motherboard replacement. if no colors appear then LCD needs replacement.

Dell Inspiron 6400 doesn't boot up properly, and won't turn off.

Try holding down Cntrl-Alt-Delete If that dosen't do it, and it's locked up, you should be able to pull the battery with minimal if any risk Profile settings must be set in administrator mode. Try booting in safe mode

Could you please run the diagonistics on the computer?
Turn on the computer. When the DELL logo appears, press <F12> immediately. Select Diagnostics from the boot menu and press <Enter>.
NOTE: If you wait too long and the operating system logo appears, continue to wait until you see the
Microsoft Windows desktop. Then shut down your computer and try again.
b Press and hold the <Fn> key while powering the system on.

Make a note of any errors that you get after running the diagnositcs on the computer.
