Latitude D800 POST Light Codes
As of this morning, my D800 is not starting up. When I press the power-on button, all three keyboard indicator lights come on, and then the CAPS LOCK light flashes 10 times before the machine turns off again. No other signs of the machine starting up are apparent.
I have tried removing each of the memory sticks I have in turn, and a different hard drive (I've been noticing hard disc issues over the last couple of days) but it's made no difference.
Does anyone know what the CAPS LOCK light flashing 10 times means? And any idea how I can resurrect my laptop?
Thanks...

Failure of a Dell portable computer built in the year 2006 or later to complete the POST (Power-on Self Test) process will result in an LED code sequence that utilizes the Num Lock, Cap Lock, and Scroll Lock. The LED codes represent specific points during the POST process of the system.
Table 1 below details what each code represents during the POST process.

NOTE: The Action That May Be Necessary column should only used as a guide for your actions and may not represent complete troubleshooting or root cause of the problem. For more thorough POST troubleshooting refer to DSN Decision tree: No POST, No Power, No Video [Dell™ Dimension™, Inspiron™, Latitude™, OptiPlex™, Precision™ Workstation].

If you've already checked the memory, try reseating the video card - there's an outside chance it's the cause. If that doesn't fix it, replace the system board.

Hi,
I believe that Dell has changed his flash codes table around 2006. I got this 10 times flashing "A" symbol on a Dell Latitude D510 that was delivered on October 2005. It was definitively a memory slot issue on the system board. DIMM B module contact with motherboard was faulty. I removed the RAM stick from this module then everything was good but my laptop was running really slow (spending its time in swapping programs between memory and hard drive).
This 10 times flashing code has been discussed a lot over Internet and I can remember I found it here on Laptop-Junction:
http://www.laptop-junction.com/toast/content/dell-caps-lock-light-flashing-blinking
It was discussed about a Latitude D610 model that has been relased to market in 2005.
You can find also some tricks on the Web to improve contact between the RAM stick and the bus on the motherboard. In case you would be just facing an contact issue between the RAM stick and the RAM slot, it could work for you. It did not for me and lead me to conclude that the contact issue was between the RAM slot and the motherboard.
Hope it helps.
PS: many thanks for the new codes table (from 2006), it helped me for a RAM issue on a Latitude D520.

So on my Dell Latitude 820, flashing numlock and capslock, with solid scrollock means that the video card is the problem? Is this correct? And the only solution is it replace the video card (which is soldered on to the motherboard) or repalce the motherboard? Any other workarounds?

PS - addition to above. It is not the hard drive - I removed that and can read it on another system. I tried different combinations in the two memory slots, whithout any success, so I don't think it is bad RAM.

Yes, the video card or its connection to the motherboard should be faulty, according to both flashing codes tables from 2005 and 2006. The codes for bad RAM slot or module are different. It's up to you to decide if renewing solders for the video card is worth the money you have to pay for such an operation. Maybe you can manage this operation by your own or you know someone who can do it for some bucks. Good luck!

I can confirm this, when I switched ram cards it worked again after the caps key blinking. Thanks. :)
