I figure there are two possibilities here. First, there is an Fn function on the keyboard that will enable/disable the speakers on command. This function is shared with the "End" key at the upper right of the keyboard, and is used in conjunction with the "Fn" key, found next to the left "Ctrl"key. Holding down the "Fn" key while pressing the "End" key will toggle the speakers on or off. Second, there is the possibility that the headphone jack has been physically damaged while the headphones were plugged into it. That jack has internal switches that disconnect the speakers while headphones are in use. If the jack is damaged, the speakers will not operate. Unfortunately, most repair shops are not equipped to replace this jack, and the jack itself is nearly impossible to buy for replacement anyway. Hopefully your problem is just the "Fn" key.

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.

Our Dell computer speakers work but the sound is not normal voices. It's like the voices are animated


It is possible that a setting on your soundcard has the pitch of the voices higher than normal or an effect is turned on that isnt required. Have you tried plugging the speakers into another source to see if it sounds the same?

No bootable device


I think you must reload the operating system and buy yourself a GOOD virus/malware protection software. If you do not have the recovery disc set contact the customer service number for your computer manufacturer to buy the set. Here is a link to the Dell support website. Support Dell US
