These is no internal fuse in the charger. It is all solid state electronics. If the battery is bad and shorted out inside the charger won't turn on.

How do i replace ide/eide cable on my dell latitude c840


Buy a replacement and fit it I guess. Why would you need to replace an item that doesn't fail?
As far as I am aware there is an adapter; http://www.ebay.co.uk/itm/HDD-Hard-Disk-Drive-Caddy-IDE-Adapter-Connector-DELL-LATITUDE-C800-C810-C840-/380698290269?pt=Laptop_Adapters_Chargers&hash=item58a362e85d and maybe a flexible cable; but that is for the screen.

Battery on dell latitude battery shuts down even though full charged


Does it work without the battery - just the adapter? Does it shut-down? If it does, then it's not the battery.

My Dell C840 Latitude has a 1.8Ghz processer but when I checked system it says it's only running 789 Mhz. Is my processer going bad?


Go Into Control Panel, select Power Options, and change Power Scheme from Laptop/Laptop to Home/Office Desk. Make sure you have AC Adapter plugged in and your should now be using all of CPU. Check System icon from Control Panel to confirm. CPU usage may show as less when laptop is booted from battery power only.

My laptop dell c840 charging status apears as idle i purchase 90w adapter and purchase 2new batries but still i am facing problem


It is more than likely the actual plug on the computer that you are plugging the adapter into. Very common issue with Dell portables and if youre still under the service warranty you will get a new computer. I worked for dell tech support for a few years and I dont think theyve changed that policy.

You could try running the diagnostics to see if there is an issue that it can detect, but it's not likely.

Tap the F4 key while the computer is starting and choose the option that says "Run Diagnostics" or "Boot to utility partition".

Dell Latitude c380 - won't power up on battrery or a/c power.


Check the power adapter (converter) with a multi-meter to see if there is power (voltage) on the connector that plugs into the laptop. The voltage should be slightly higher than the voltage that is printed on the label on the adapter.
If there isn't any voltage or very low voltage, it is faulty and you need a new adapter.

AC Adaptor DELL PA-12 checking


See what the output voltage the adapter says, it may be 19.5VDC @ 3.34A.
Set the Multimeter to read 20 volts DC or more.
Put the Black lead on the outside of the plug (negative), and the Red lead inside the plug (positive).
They usually have the positive as the hole in the plug.
Look at the reading on the meter, if the power adapter is working it will read around about the stated voltage but none of them are completely accurate. It may be a little more or a little less.
If it is nowhere near the stated voltage then there is a problem with it.
