Dell Inspiron 560 Keyboard Failure

Specs: None, Intel Core 2 Duo E7500/2 GB DDR3
Hey everyone,
I have a Dell Inspiron 560 that does not boot properly. When the computer is turned on, the fans start running at full speed, but the POST screen does appear. Shortly thereafter, a screen comes up with this message:

"Alert! Previous attempts at booting this system have failed at checkpoint [0085]. For help in resolving this problem, please note this checkpoint and contact Dell Technical Support."

Below that there are the messages "Keyboard Failure" and "CMOS Checksum error." It prompts to press F1 to continue, F2 to enter setup, but this is where the problem is. The keyboard is completely unresponsive. I can't do anything except press the power button and shut down the machine. I've tried different brands of keyboards, different USB ports (front and back, there are no PS/2 ports), and still nothing. Also, at this point, the system starts making 5 beeps in a row, the fans are still running at full speeds, and the power button is blinking orange.

Any ideas on what to do? I have already tried:
1. Unplugging the system and pressing the power button to drain power for 15 seconds.
2. Resetting the BIOS by using the CLEAR CMOS jumper.
3. Removing the CMOS battery for 15 seconds while the system was unplugged.

Only 1 RAM stick is plugged in, and all add-in cards and hard drives and CD drives are unplugged from the motherboard. Thanks!

I couldn't find a listing for the various Dell checkpoint codes. Perhaps the beep codes for that model will tell you something. You should download the manual if you don't have it:

but I think 5 beeps is 'real time clock failure' so it may be something as simple as a dead cmos battery, although it's hard to believe a dead battery would cause such a big problem.

You may need to contact Dell if it turns out you need the checkpoint codes to figure out where the hardware problem is. It doesn't seem like those codes should be a big secret.

Hey DAVEINCAPS, thanks for your help! I tried switching out the CMOS battery with a known good one but to no avail. I did see that the 5 beeps was an RTC failure, but I do not know what further things I can do if replacing the CMOS battery doesn't help. I will try to contact Dell today and I'll let you know the result.

I tried to contact Dell Support, but because the system is out of warranty I cannot chat with a technician online nor call phone support for free. I think I may post this question in the Dell forums and see if anyone there can help me. Thanks,

You're welcome. I think there's a good chance the checkpoint codes are standard for Dell so if you find what 0085 means for one Dell it probably will be the same for yours.
