Dell Latitude D600 - RAM not recognized

I just added 2 fresh 1GB DIMMS to my latitude but on startup it is only showing 1GB of RAM. I believe the D600 is rated for up to 2GB. Ideas?

...a few ideas...

1.) Try reinstalling the RAM. Clean the ram dimms and the slots before you plug the ram in again. This might be due to some dust in the ram slots.
2.) Try plugging in dimm no1 in slot no1 and leave the second dim out. Boot and see if it detected it. Then do the same with the second to see if one dim/slot is not working.
3.) Check your bios options.
4.) Try updating your bios.

I found a couple of different websites about the max memory of a D600. One said 1GB the other said 2GB. Without a clear idea, your best bet would be to boot up 1 stick at a time and test each slot. This may you can see if each stick is good and each slot is good. If both sticks work
independently in both slots then you know your D600 is only good for 1GB.

One of the DIMMS might be incompatible or faulry.
Put one DIMM in at a time to determine which is not working.
If they both work separately then it appears they are incompatible together. Try to get the DIMMs from the same manufacturer, with the same specs.

That would probably be DDR-333 (PC2700) Notebook Memory. I believe a DDR-400 wil also work since it should be backwards compatible.

You should be able to order Dell parts online using this link

You will need to register with the Dell Online shop first though :)

I turn my Dell Latitude D600 laptop on and startup screen shows as usual but then it goes to a black screen. Can you help?

If your computer keeps on running after it turns black the problem maybe is the LCD. However if the computer is not running after it went black then possible problem is with the MOBO (Mainboard)

Hope it helps.

Upgrade RAM in a Latitude D600. one bay seems to fail

The memory bay is a part of the motherboard. Try each stick in each bay to make sure that the problem is the motherboard itself. Sometimes memory is incompatible with a particular laptop. Sometimes there is a maximum allowable memory. The maximum for your PC is 2 GB.

DELL LATITUDE D600 has low configuration by itself. many od the softwares that exist today required more configuration as compare to what DELL LATITUDE D600 has.

Anyway, Download "WinXP Manager", it will remove all the junk files plus unused or error registry key and even optimized your system.
Here is the download link

Note :  you need to download  "Microsoft Dotnetfx 2.0 or later " in order to install WinXP Manager.Install the software and clean all the junk files and registry error and optimized your services.

Now Scan your PC  with a Good Antivirus like Kaspersky Internet Security 2010 or A-squared Anti-Malware with their latest updates installed.Both of them can detect Spyware, Malware, Adware too.

Make sure you have enough free space in your System Drive (usually c:).

Uninstall all the softwares that are not needed,remove the desktop shortcut as much as possible.

Click Start----Run----type "msconfig" then press enter
Click "Startup" tab and untick all the softwares that loads during system startup except yout Anti-Virus program.

Again, Click Start----Run----type "services.msc" then press enter

Disable all the services that you don't need.

Some example are : Automatic updates,error reporting service, help and support,remote registry, theme etc. It will save lots of CPU and meomory lifecycle.

Now, right Click on "My Computer " icon and select "Properties" and Click the "Advance" tab.
Under Processor click "Settings" button
under Visual effects,Select "Adjust for Best Performance",
Click "Apply" then "OK"

After all this Reboot your system and check if it help you a little.

I don't recommend you Disk Defragmentation as they speed up the system files access time only in theory.

If the problem still persists, Consider reinstalling your System.

Adding one more Physical 1GB RAM will boost your speed upto 50%.

That's it.

Changing cpu performance

Update the BIOS and the chipset from the manufacturer.

Uninstall the unnecessary softwares from the system.

Clear temorary files and folders.

Try to do a disk defragmenter on the hard drive.

If your system has low RAM (256/512 MB) then it is advisable to increase the RAM to 1 GB / 2 GB.

Have very few startup programs (to change the startup programs Go to Run -> msconfig -> Startup.

Hope this helps.

My dell latitude d600 is not recognizing any wireless connections. I believe the switch is at top of the keyboard and it doesn't seem to be working. Any advice

if it is not seeing any wireless networks, the wireless card may be defective, try having it tested, or check the device manager to make sure the drivers are installed correctly for the wireless network adapter

2 second log on the logs me off.

Do you see the BSOD (Blue screen of death)?

Sometimes when you use the suspend feature, the cache data can cause the problem. If you laptop allows you to have a fresh start, please choose that.

If that doesn't work, you should try booting from a OS CD. The last step would be to determine if either the Hard disk is corrupt or if there's a problem with the RAM. It's usually these devices which can cause a start up problem.

Dell Latitude D600 hot

this is perfectly normal. Ram is constantly written to and erased thousands of times a minute. This causes it to heat up. On older laptops like the d600, they don't have a great method of cooling it down so it does get hot. Mine gets hot enough to burn me if i hold it wrong. Just make sure when you are using it, that the bottom gets away from the surface its on once in a while, and you should be fine.
