Question about Dell Inspiron 8200 Latitude C840 Laptop Keyboard03J247 CD-ROM Drive
When the power is turned on - the led 's come on and the center lite--the little lock with the "A" on it flashes a half dozen times and then power turns off. The other 2 little lock lites don't come on at all. Tried the memory sticks thing but that didn't work. Can anyone please help?/ Thanks.
Quick power off means a hardware fault. Remove the memory sticks and boot the laptop. If you get an error message, the memory sticks are bad. Replace them. If it still doesn't boot to BIOS, your motherboard has failed and needs to be replaced. It can't be "repaired" cost-effectively. And since the Inspiron C840 is a very old laptop, probably not worth fixing. You CAN get your data off the hard drive by slaving it to another computer. Google " hooking up an external hard drive".

One of the greatest factor in intermittent shutdowns is because of heat issues. try to check the fans if they are all spinning. if all fan's are ok then you only need to replace the motherboard. here's a manual that might come in handy http://support.dell.com/support/edocs/systems/dim5100/en/sm/index.htm
Hope this helps.

Here is what you need to do. Disconect the module with the usb ports from the motherboard. It took a while for me to figure it out but a damaged usb port will make the computer go nuts.

The 3 LED's (Num Lock, Caps Lock, Scroll Lock) are used by Dell to diagnose no-post issues such as yours. The only error code close to yours is [Num Lock ON, Caps Lock FLASHING, Scroll Lock ON]. This indicates a a memory error. Try reseating the memory modules. If you have 2 memory modules, insert one at a time to determine the faulty module.

Most probably the seating of the processor on the motherboard is not proper
check this site and mount the processor properly
