Hello

shut down computer - unplug power cord from laptop - remove the battery from laptop - plug Ac adapter into computer and Ac outlet (wall)
turn on computer
if computer does not turn on, replace the AC adapter and cord - then place battery back into computer
plug in new Ac adapter and cord - recharge battery - if orange light stays on after 4-6 hours of charging battery, you need new battery as well - replace battery, charge it up and it should be fine

if you have attempted these steps before and no change occurs, then you may have issue with power connection in computer - locate a service centre to replace power connection on computer

What do the activity lights on the keyboard of the Dell Laptop C640 represent?


To the right of the power button and below the Dell AccessDirect button are three lights. These have a lock synbol below them. The first one from left to right is signified by a number 9, this light is turned on when the numberical keypad is enables. The center light is signified by a letter A, it is on when the uppercase letter function (Caps Lock) is enabled. the third one, far right, signified by a down arrow, is on when the scroll lock function is enabled.

The device status lights on the far right side near the front of the laptop case. The top light is the power status light, the middle light is the Hard drive activity light, the bottom light is the status light for power management, battery, AC etc.

I have a Dell Inspiron 6000 laptop computer and I'm experiencing a problem with the orange battery light flickering continuouslyl; though the green battery light is displayed. Thank you


I think you may be referring to the green power light and the orange hard drive activity light.you should have a power icon located on the bottom bar on the desktop near the clock that indicates battery power.

When swiching on will not stay on


Not good Tony! Try removing the battery. Does it work now?

Try the opposite, no AC and just the battery. Does it work now?

If not, other things should be disconnected. Like hard drive, CD, memory, and virtually anything else you can remove to see if a part had failed and causes the machine to turn off.

Otherwise it might be time for the shop. Sorry. :(

Dell Lattitude C840 Laptop


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.

Gx260 pc wont start


Have you checked the post lights located in the back of the system by where the keyboard plugs in? There are is a row of 4 lights; either yellow or green. If the systems gets stuck at a particular post location, the lights will tell where. Good luck
