Possible memory issue. Try Reseating your memory card on the system, it would be helpful.

The only solution i have found for the flashing 9 lock symbol is to remove the battery, then remove both (if there is 2) sticks of memory then replace one in the opposite slot. Plug in the power adapter and try restarting. That worked for me, once it started i checked for updates and then turned it off and replaced the second stick of memory and then the battery and while unplugged restarted again.
This is the second time i have gotten this fault, and no-one seems to know what it is. It seems to be some kind of error with the system state but i cannot find a reason as to why that is. But as long as my solution works i don't mind too much.
Hope this helps.

I cannot shut off the 'fn' key from its calucations display.

If you press and hold the Fn key and then simultaneously press the Num Lock key at the top right of your keyboard you either enable or disable the Alternative Symbols of the following Multi-symbol keys:

Num Lock Disabled: M . / J K L ; U I O P 7 8 9 0
Num Lock Enabled: 0 . / 1 2 3 + 4 5 6 - 7 8 9 *

Try reseating RAM. The flashing lights indicates a fault on the motherboard. I read online where this fixed many laptops but not all and not mine. I suspect the motherboard is dead in my case. May be same for you but first try reseating RAM, hard drive and maybe the processor.

Dell Laptop 1510 turns on with a flashing Lock but doesn't boots up only flashing Lock

That is because the BIOS password has not been entered in the time required.
There are a number of web sites that cater for this problem but contact Dell first.
Hope this helps.

On boot up a lock symbol with a '9' is lit & nothing else happens

the "9" inside a lock means that your Num Lock button has been pressed. If all you see is the ">" then maybe you are looking at what's called a DOS prompt, and I have no idea why that would display. Try holding the Power Switch for 10 seconds and restart your computer. Hopefully things will be better, and you know where your Num Lock key is.

Laptop Won't startup Vostro 1500

See if you can run the Pre-boot System Assessment (PSA) diagnostics. To run the PSA+ Diagnostics on this system, perform one of the following actions:

1) Hold down the <Fn> key while pressing the power button.

2) Turn on the system, press <F12> at the initial Dell™ logo screen, and select “Diagnostics” from the boot menu.

3) Disconnect the AC power and remove the battery. While holding down the power button, insert the AC connector into the back of the system. The system then starts and the message “Diagnostic boot selected” displays. The system then launches the PSA+ Diagnostics.

According to Dell specs, there is no error code listed that you described, (Flashing Caps LED). Also try reseating the memory modules, (you might want to try this first).

Laptop won't startup

Try removing your battery and then putting it back. If that doesn't work, then either your hard drive is bad or maybe even your motherboard is bad. If you can get into your computer's BIOS, check and see if it will allow you to do a system restore from the BIOS page. As stated above, it is probably that your hard drive is bad.
