My Dell Latitude 850 has three lit up lights on the face of the laptop that look like little LOCKS. When I try to turn onthe laptop these two or three lights light up, then the laptop turns off. I cannot get the laptop to turn on. WHen I am fortunate to have it turn on...all the lights are not lit. What is happening and HOW CAN I REMOVE THE LIT UP lock state on this laptop? It is so annoying because it seems like it loCks me out from booting up. GRRRR I feel like I have the DELL FROM HELL.

Solution #1, Go to RUN type in 'msconfig'.
In startup uncheck MotiveSB.
Try to reinstall the keyboard driver. Solution #2
  Sounds like it may also be dirt or some spilled soda.
-- Had the same problem after an OJ spill. --
If you feel comfortable about removing the keyboard, disconnect all the wires and cables, then give the keyboard a thorough washing. Then let it dry overnight.
If that doesn't sound like something you want to attempt, then you will have to take it in to a computer shop.

get to the main board of ur system there is a jumper near the battery .
change its position while power is off and get it back to its previous position. this way u will reset cmos to default.
if the computer starts hit delete to enter setup and load system defaults.save changes then exit.
ps: defected processor could be the cause

SOURCE: Dell Optiplex GX280 boot-up problem

Guess what? it's the CPU. Changed it with a working PC same type and unit boots up fine. Guess we learn about new problems everyday.

I think it's high time these units start telling you what component or section of the computer is faulty...too many things to diagnose.

SOURCE: Dell C400 Laptop Battery not charging

Go into the battery properties and check if the battery is charging. If it says it is, then test it, use the battery to see if it really is charging, they will sometimes give a false reading. If it's not charging, then check the power supply with an ohm meter for the proper output. If this all checks good, but the battery isn't charging, then I'm afraid you have a failed power management system on the motherboard. The power management system controls the charging along with other power related aspects of the machine. If the power management system has failed, then unfortunately, you will have to replace the motherboard in order to fix it.

Dell Inspiro 6400 not starting up


If the Num lock is lit constant, and the Caps Lock and Scroll Lock keys are flashing, the system is reporting a memory error. Power off the system, remove the battery, and follow the user manual from support.dell.com to reseat the memory module(s). If the error persists, you may need to replace the memory and/or the system board of the portable.

Comp wont turn on


ok, all three lights is a hardware problem - this is usually related to CPU problems in the machine but can also be a sign of MB faults too - first up - remove and replace the ram - both sticks - one under the kb and the one in the bottom cavity too - if this doesnt work - i suggest either taking it in for checkup to a qualified service centre or if your feeling confident then remove the palmrest and heatsink, unlock and reseat the cpu and then try starting again

cheers

Dell latitude d600 doesn't turn on


The test Dell advises to narrow down this issue is to remove the battery, hard drive, ram, and optical drive.  Next plug in the a/c power cord and you should get some LED's coming on. If not it points to the motherboard.

Control board light on d600 want stay lit. It comes on for a few seconds then turns off.


I'm not sure I'm understanding your problem. There are three lights on the machine, power, battery and hard drive. Is the machine working, starting then shutting down, or not working? Please give me a little more info and I'll be able to help.
