20 Most Recent Dell Dimension 4600C PC Desktop Questions & Answers


This is a relatively common problem in the Dimension 4600c. The small, fan-less heatsink for the Northbridge chip (a memory/video-to-cpu communications chip) is held down by a spring, which is anchored by two small wire loops soldered to the motherboard at locations marked "HS2". The spring completes an electrical circuit between the two wire loops. The spring puts a substantial force on the minscule bit of solder holding the loops to the motherboard, and was a poor design.

If a loop breaks off, the circuit is broken, which tells the BIOS that the heatsink fell off. To fix this, you need to 1) secure the heatsink to the chip, and 2) reconnect the circuit between the two "HS2" locations on the motherboard. I have sucessfully used this solution. This solution will not necessarly stand up to a lot of abuse if the Dimension's enclosure is frequently opened and closed to replace other components such as RAM and hard disks.

0) unplug the computer.

1a) Recover the heatsink, spring, and loose wire loop. Discard the spring. Get:
- a fresh tube of thermal paste from Radio Shack or other electronics supply store,
- some epoxy,
- a round toothpick,
- about six inches of insulated 14 to 20 gauge solid copper wire,
- electrical solder, flux, and a soldering iron,
- and a box of cotton swabs.

1b) Using pure alcohol and lots of cotton swabs, clean *all* of the existing thermal paste off of the Northbridge chip and the bottom of the heatsink. When both are dry, apply a dab of paste to the center of the Northbridge chip. Use a round toothpick like a kitchen roller to spread the paste evenly across the small raised center square of the chip.

1c) Apply small daps of mixed epoxy just outside of the four corners of the raised center of the Northbridge chip. Place the heatsink onto the Northbridge chip, centering and squaring it as best you can. Press firmly to make good contact with the thermal paste. Allow epoxy to dry.

2a) Firmly seat one or both detached wire loops into their mounting holes at the "HS2" locations. While pressing down on the loop, apply a small dab of epoxy to one end of the loop to secure it to the motherboard. Allow epoxy to dry.

2b) Strip the ends of the copper wire, and bend the wire so that it can reach around (rather than over) the heatsink to the two wire loops. Solder the ends of the wire to each loop. Knowing how to solder is an exercise left to the reader. "Use head main ting": don't drip solder onto the motherboard.

You can now plug in the computer and restart. The BIOS and/or OS may have saved the error state and return a different message about the heatsink issue. You may need to reboot a couple of times to allow the BIOS to notice that the "HS2" circuit is (hopefully) now complete. When you've sucessfully booted the machine, shut it down and gently close the Dimension's enclosure.

Hello there and welcome to fixya
There may be a few things that can cause this problem.
I you feel comfortable opening up the computer case and looking around great if not have a friend or a computer repair shop do these repairs.
First i would unplug the power then open the case and remove the power supply cords that go to the motherboard this will help release any static that may be produced next find the battery and remove it
once this has been done press and hold the power button for at least 5 seconds this will release any built up power on the board
now see ifthere is any lint or debris around the fan units if so get them clean blocked fans are the leading cause of motherboard failure because it overheats due to the lack of air suppliedd to the board ok?
Now once this has been done find the memory sticks and remove them 1 at a time and make sure they look to be in good shape and not corroded if so great make sure there is no lint in this area too then replace them and now check any cables or ribbon cords from the cd drive or the a drive or any other drive that may be attached
to the board now once this is done replace the battery and replace the power supply cords back on the motherboard
and any thing else that you have disconnected then plug the computer back in and now try it you will be brought to the time and date screen which is normal simply set the time and date ok
Please let me know how this works for you and if you need any thing else please feel free to post me a comment
Best regards michael

Test your PSU power supply unit or replace it if your power supply units fan is not working your PSU is faulty

One bad lead can cause a computer to continue on a cycle of restarting or to shutdown or fail to detect/ boot up a computer hard drive


Test all leads that attach to your hard drive power and data cables IDE SATA

the leads from your MOTHERBOARD TO YOUR HARD DRIVE make sure they have a secure dust free connections and are not faulty or just replace them they could be faulty

make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electrical extensions or just replace them they could be faulty a computer needs its connections to continue its cycle and have an end so any faulty leads will end up with a computer error

even something as small as a faulty electrical or fan lead can cause you problems

computers need all of the data and electrical current to travel through every working device and to have an end to be able work properly


motherboard and a hard drive any leads between them will fail before your motherboard or your hard drive if its a flat ribbon 40 pin type IDE replace it this will be the first to fail


check all electrical power input and extensions make sure they are securely seated even the cd/dvd floppy drives need to have current go through make sure these drives are working


also check the Cmos battery and computer RAM modules make sure they are securely seated with no dust built up or in the sockets on some motherboards cmos batteries are soldered in
check you CPU central processing unit make sure its securely seated and has thermal paste

hope this helps

Try the check disk utility.

To run the check disk utility you will need a repair disc or a operating system disc. Put the disc in the cd drive and boot from it. You want to get to the Dos Command Prompt (Black screen with white letters) and type the following command: chkdsk /r
Check disk will run well over an hour or two and you will notice the percentages going from high to low, this is normal. Let it run to completion. Then reboot machine.

If check disk fails to solve your problem you might have to reinstall windows. Try doing a Repair Install that way you don't loose your data, documents, music, pictures, videos or programs.

In windows xp you get to the dos command prompt by selecting R for repair when the options appear.

In Vista and Windows 7 you want to get to the recovery console and look down at the bottom of the window for the Dos Command.

Try the steps below if check disk did not solve it.


When you plug in the power cord is there any lights whatsoever on the laptop, where the plug goes in or on the AC Adapter of the power cord?

When you press the power button do you hear fans running, hard drive spinning, lights on the computer, hear any beeps or lights constantly blinking, hear the DvD/CD drive click and the light on the drawer of the DvD/CD turn on for a second or two? If so the laptop is trying to boot or may have booted, but the screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with the laptop and why it is not booting. Most times it's a motherboard issue when you hear beeps or blinking lights continuous. Most times the problem is with the memory or Video Card. Count the Blinking Lights or Beeps and take note of their pattern (1 Long or 1 Long followed by 2 Short).

Maybe your power cord is bad if you don't get anything to happen whatsoever when you press the power button. And if that's true maybe you was operating off the battery the last time you had it on and since the power cord is bad, it was not charging the battery so the battery is drained and the power cord is bad.

Maybe you have a Static Charge Buildup. Remove the Power Cord, Remove the Battery, then Press and Hold the power button for 30 seconds. After 30 seconds plug the power cord back in (leave the battery out) and hit the power button to see if it boots. If it does, you can put the battery back in and let it charge.


Maybe your DC Power Jack which is where the power cord plugs into the computer is bad. Take an ink pen and push the tip inside the jack and see if the little pin wiggles, if so the jack is bad. You'll have to take the laptop apart to fix it. Most times it is soldered onto the motherboard, so you will have to desolder the old and solder a new one.


Maybe your memory is bad or the memory slot is bad.

Remove the Power Cord, Open the Case and remove one of the memory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x on it with an ink pen. If it fails to boot then move the chip to the next memory slot and try rebooting. If it fails take the chip out and set it aside, then put the other chip in and try booting it in both slots. If it boots, just to verify that the chip set aside is bad, mark an x on it and put it into the open memory chip slot and try booting.

You can download the PCI and device drivers from Dell WEB site,the support download page. Make sure you select your model desktop or laptop,better still, type in the Service Tag number, it is printed on the label on thebottom of the laptop and on the back or sides of a desktop. (If the Service Taglabel is missing then go into the BIOS setting and on one of the BIOS pages,the Service Tag number will be displayed). This will open the page where thespecific drivers for your model computer are located. Also make sure you selectthe Windows of the drivers for your Windows operating system.

Hi,
Issues like this should be reported to Dell , if your system is still covered by a warranty then they can send a tech to further check it.
Burnt smell can come from several parts of the system like power supply , motherboard , fan , etc. and it can be hazardous if not checked by a professional.
What I suggest is that you call Dell technical Support.
Hope this helps
Thanks
Dennis

I would use a piece of thin coat hanger, and bend the configuration I need.

http://support.dell.com/support/edocs/systems/dim4600c/sm/sffprcsr.htm

Make the configuration very close to the original green Securing Clip.

OR,

Go to Dell Spare Parts, and see if you can buy the Securing Clip.
Have the Serial Number written down. (S/N)

I didn't see it by searching with Dimension 4600C.

Not the best solution I'll admit. The only other thing is to search the internet for the clip, or buy another motherboard.

Hi scotteg71121...

The alert is caused by a loose chipset heat sink.
Dell has a self test that prevents further damage by halting the system and displaying the message Alert! Chipset heat sink not detected. System Halted.
The solder joint seems to fail from constant tension and heat.
If you find the missing clip inside the computer you can solder it back in place and reattach the chipset heat sink wire hook.
If you can't find the clip you can replace it by bending a thin piece of wire in a half circle.
You can see a picture of where the clip goes on your computer motherboard by following the link below.

it means that the chipset heatsink on the motherboard has come loose. There is a sensing circuit that is closed by the spring clip that holds the heat sink in place. One of the loops on it has broken, causing the error.
Resolution is motherboard replacement

Yes, you need to re solder the missing wire loop loop to the motherboard. If you can't find the loop you form one by bending a thin piece of wire in a half circle. You will have to remove the motherboard to solder the clip back on.
