C840 resolution difficulties...

My C840 does not accept changes in resolution correctly. The default or native resolution is 1600 X 1200. When instructed to use a lower resolution it shrinks the display leaving a large black border around the perimeter of the screen and then reports that I am "attempting to use a screen resolution that is not optimzed for my computer". The key item that I noticed is that although it is changing the screen size the card is not expanding or "fit to screen" the result after the resolution is changed. I've reloaded video drivers and had no luck. Also, I noted that the first time this occured was while it was booting up. The typical "Dell" splash screen came up as usual and then was shrunk down to about 1/2 of it's normal size. From then on the only resolution that would fill the screen was the largest setting (16K X 12K) Do you know what could cause this??? Thanks in advance, Chris

Re: C840 resolution difficulties...

The type of screen you have is a UXGA screen. the optimal resolution for that is 1600 x 1200. changing the resolution for that will distort the screen causing black borders. If a computer has a 15.0+" SXGA+ screen with an optimized resolution of 1400x1050 and the screen's current resolution is set to 1280x1024 pixels, the display will shrink resulting in a black border surrounding the edges of the screen. Also, all other lower resolutions may be stretched to fit the screen. No border will be visible, but fonts may appear slightly fuzzy.

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.

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.

Display pixelized

Pixelated is a pretty generic description so doesn't help a lot, however, it could be you started your notebook in Safe mode, where Windows defaults to a low graphics setting for maximum compatibility with all hardware. Or, maybe you changed the video display settings yourself? Your native screen resolution is probably 1200 x 800, check the display setting to see if that's what it is set at now. Also check the HP.Com web site to see if they have a video display driver you can download, maybe your driver got deleted or somehow corrupted.

Dell Lattitude C840 Laptop

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.
