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.

Optical drive not recognized in Bios


You have either a bad optical drive or optical port. You can still load the OS but you need to make a bootable USB drive and install that way. Or get and use an external USB optical.

also, check in your bios or for the drive settings, it may be set to only accept sata drives or the port may be disabled. some latitudes give the ability to disable or not look at a specific port.

Dell latitude c840 slows same time fans come on, approx. 4-5 minutes after start-up. Ran laptop in cool, not cold environment; no noticable improvement.


have the unit cleaned out good...if problem still exist your laptop may be on its way out

the slow down is due to a drop in power available to the processor, and this can damage it beyond repair.

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 dvd plays cd but not dvds


Try using a good quality dvd cleaner first. If that does not fix the problem then it is an optics issue for the dvd & it would be cheaper to replace the drive than to try & have it fixed. Hope this helps.

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.
