Hi Mazhawedzat,
1.) Please make sure your Notebook AC Adapter is properly connected. 2.) And check whether your getting an output from your AC Adapter.There are chances of Adapter failure. 3.) Remove you Notebook Battery and connect your notebook to the AC power.

Probably battery problem. If you can find someone who owns the same lapto, try her/his battery on yours and see what happens. Otherwise, replace it with a new one.

My daughters power supply for her C640 has a pinch


I suggest you DONT USE PINCH POWER CORD FOR SAFETY.

PLEASE TELL ME IS YOUR POWER CORD & THE PINCHED CORD ARE SAME? I MEAN SAME MODEL? AFTER PLUGING OF YOUR CORD, THE BATTERY CHARGING LIGHTS ITS ON? IF NO THEN I GUESS THAT CABLE NOT SUPPORT HER LAPTOP.
VISIT A DELL SERVICE CENTER OR A SHOWROOM AND BUY NEW CORD WHICH IS MADE FOR YOUR DAUGHTER LAPTOP MODEL.
OTHER WISE SOME CHANCES OF SHORTCIRCUIT ON MOTHERBOARD.

Thanks, i am waiting for your feed back & if you satisfied then thumps me please.

My latitude c640 batter do not charge green and yellow light flash when ac plug in


The flashing LED is indicative of a failed battery. The battery for a protable system has a expected lifespan of 300 to 500 discharge recharge cycles, then will eventually fail. If you haven't replaced the battery that is the next step. If the battery has been replaced with a NEW battery and still doesn't charge, then the motherboard would need replacement.

Dell c640 charging problems.


Instead of spending alot of time trying to do something that could potentially harm your laptop..why not just buy a power supply?

You can get one here Click here for about 16 dollars. That's a great deal they are usually about $60 and its a Dell brand not some off brand.

Dell Latitude c540/640


Windows Vista is not supported on Dell Latitude C540/C640. There are no drivers for the hardware of this model. Many older computers have that problem. You can try Microsoft to see if they even exist: http://www.microsoft.com/uk/windows/products/windowsvista/buyorupgrade/upgradeadvisor.mspx
You might have to fall back to XP.

I'm sorry to say this, but the water has killed your keyboard, and you will need to replace it. There's no way of fixing it, other than replacement.

Dell c640 battery problem


This sounds like it is not getting enough amperage from the power brick- check which model power brick you have. I'm not 100% sure but the pa-6 family may not provide enough power to charge and run the laptop at the same time. the PA-9 should- if it's rated at 4.51 @20v - that works out to about 90watt. If you DO have a 90 watt power adapter and it's still giving the orange then red flashes- and will not charge when the laptop is off- you probably have either a bad battery, or the motherboard is faulty and has a bad charge circuit, or a loose power jack. What does pressing the little button next to the charge indicator on the battery do? Flashing every other led- 1,3,5 is BAD, so is 1 and 5. You also might have a 3rd party refurb- that had the guts torn out and is not properly "seen" by the laptop.

Blinking red light


What laptop brand and model is it? And where is the LED that blinks? Important details! Some laptops have a power light that blinks red while battery charges, then it turns steady green when battery is full. Some laptops have a red LED that lights whenever there is hard drive, CDrom, or floppy activity (read/write). This all depends on your laptop brand/model and where the LED is (side, near floppy/CD, top near screen, or on battery itself... so provide more details for me, please!
