I have a Dell Inspiron 1545 laptop, and my computer would not boot up. I then ran a diagnostics test, and it came up with the error code 2000-0123. What is the problem, and what should I do?

this is a bios level error, you should still be able to run the system. this code is something you get when you hit F12 and run the diagnostics? or is this a blue screen error? you are probably going to need to boot to F2 (setup) then hit "Alt e" Alt F then Alt B the system will beep on the alt f but that's ok once this is done hit esc, save changes and reboot and see if you still get the error

The drive is bad and will only get worse.

Have you tried Safe Mode, Last Known Good Configuration or booting to your Operating System disk

Hi
It seems that the Hard Disk is disconnected from it's connectors
It needs to be fixed and installed correctly.
To do that, there are screws in the back, remove them and disconnect the hard disk, and reconnect, fix it correctly.
If it's difficult to you, go to technician to do that.

Please, Tell us your results.
Good Luck

If you ran diagnostics with an empty cd/dvd drive you will get error code like this.

If means that cd/dvd drive was not able to find a good media.

If you are still getting an error even cd/dvd reads any media during the test, i would suggest to replace your hard drive.

Hope this helps.

That error code is indicative of a primary battery permanent failure. There may be a connector problem but not likely. Your best bet is to replace the battery.

If you are uncertain, try finding someone in your vicinity with the same type of laptop as yours and ask if you could test their battery on your computer.

Your hard drive is defective or the circuit (system-board) that controls it. It's cheaper to replace the hard drive then the system-board to see if that's the problem. If it's under warranty Dell will replace either parts.
