Lattitude C600 - No start

You didn't say what you were doing, on-line? In a Program/software? I would start by running a Full scan with your up-to-date Anti Virus. NEXT, Download freeware MALWAREBYTES at : http://www.filehippo.com/download_malwarebytes_anti_malware/ In the install, UNCHECK the TRIAL PRO version, you want the freeware version. Run a Full Scan, Delete ALL results, Reboot. NEXT, Download CCLEANER at : http://www.filehippo.com/download_ccleaner/ This freeware program will clean the junk from your machine. In the TOOLS section, STARTUP section, Disable ALL unnessary startup programs, this will speed up your starts and running. Here are other speedup tips : http://www.techrepublic.com/blog/10things/10-ways-to-speed-up-windows-7/3332 AND: http://www.pcmag.com/article2/0,2817,2364937,00.asp

Check your display properties in control panel.

Josh, There are several possibilites. Lets start with the easiest.
1. Are you using the original power cord? The wrong cord will heat the system up.
2. Does your motherboard fan come on?
3. did you upgrade from windows XP to Vista?

boot up in safe mode. Start -> run -> sysedit.

De-select all items on bootup. Now reboot. If that works, then re-run the utility, check one thing at a time, reboot, and test. Keep going until you find the culprit -- then remove that item.

Another easy fix, depending on your version, is to run system restore and bring it back to a point in which it worked. Start-programs-accessories-system tools/system restore

hope that helps.

which side of the laptop is getting hot?
if it is the left side, check the bettery. it may need replacement.
if it is the right side, then the HHD need is on its way out, better backup all your files NOW and get a new hard drive.

First I'd try to install the latest driver:
1. Go to http://support.dell.com
2. Click on "Drivers and Downloads"
3. Your best option is by using the service tag code (usually on the bottom of the laptop), but if you can't locate it, use the select by model option.
4. Click the plus next to Audio
5. Download the newest driver and install.
6. After installation, reboot and see if it worked.

hi there, you can try this unplug the powercord from the pc and remove the battery and than press the power key than replace the battery adn plug in the power cord and let it charge for a hour or so and than try it again. if it boots good if not try to press the del key right after you turn on the unit and check the settings of bios to see what they are set at and try to set it to default or failsafe than save on exit and reboot and see what that does

It turns on and shows the BIOS screen? Can you access via F2? If it shuts down, check the RAM and RAM slots! Wrong CPU can also imitate a dead machine

Here goes, first download the A12 BIOS from this page or others,

http://drivers.softpedia.com/get/BIOS/Dell/index5.shtml

Then, Run this file to make a bootable bios floppy disk. Reboot the laptop floppy will start dos mode, the updater will detect any bios newer then A12 and say finished without changing anything and come to an a: prompt.

type dir for a list of files on the floppy. If your typing gets you wierd symbols try holding the Fn key (lower left) lookfor the filename C600_A12.exe or somthing like this. type it at the a prompt exact. The bios flash will check system bios and ask your permission to revert back to A12. say Y.

Computer will reboot. take floppy out.

My batteries charge grat now, but I don't get all ythe settings pages in Bios that I should, It seems to hang when i enter Bios. Laptop works fine though. i have installed and tries all bios from A12 yo A23, the A12 seems to be the best. No problems from winXP.

there is a needed interface for the tv. the video signal your laptop generates is not compatible with the input circuits of the tv.
