try using the usb mouse then go into control panel>system>hardware>device manager. Click on the +sign next to touch pad or pointing devices and right click on touchpad, then click on uninstall. Reboot the computer, unplug the usb mouse and the touchpad should be picked up as new hardware and be re-installed.

It is the backlight! That laptop uses a fluorescent lamp. It is bad.
If you look carefully at the screen, you will see the Windows desktop (or whatebver you are running). It just needs to be lit up.... from the back. Tel them to replace the LCd screen or replace the lamp.

Hope this helps!

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.

White screen on C840


Hi There,

A white screen is almost always the symptom of a failed LCD. The easiest way to check this is to connect the laptop to an external monitor. If it displays normally there, you've got your diagnosis, order and install new LCD. If the white screen is on both the external and the laptop monitor, the problem is on the motherboard and almost certainly the video processor/controller chip. That's when you have to decide whether to send the laptop to a motherboard repair facility (many on eBay are quite good), comparing their prices to acquiring a different used/new laptop.

If you are capable of replacing a motherboard yourself, you can look for replacement mobos online. Sometimes these can be reasonably priced or so incredibly expensive that it defies reason why they are even trying to sell them.

Good Luck

Dell C840 no power is there is a fuse?


Hi

Thank you for your query

Please try the following

1) Ensure the fuse in the socket has not blown,
2) Try to obtain a replacement power lead to ensure the lead is not faulty

I would not recommend that you open the Laptop as only qualified engineer's should carry out this work

If this has been useful please leave postive feedback/vote/testimonial - Thank You Again

Display on Dell C840 has blackborders at low resolution


That should be normal. If you use a resolution that is lower then the physical device it will leave the edges black. If the screen printing is to small change fonts and icon sizes instead.
