Have you checked to make sure it wasn't the power supply? If this motherboard is still inside the pc and the cd/dvd lights up, or the network card shows life, fans, case lights, etc: than I would rule bad mobo. If nothing shows signs of life, try power supply or even better maybe a lose connection.Check all cabling and wire plugs. Clean out any dust.

check if the power cord is correctly attached and current is available.
If you then hit the power button and nothing happens, this means the power supply is down. This compenent can be sold in any local specialized computer dealer.

My house was struck my lightening and then my Dell Dimension 4600 would not power up. I checked the hard drive in another computer and it works. I replaced the power supply but still get no responce...


It appears the motherboard is dead.
My choice of motherboards are Gigabyte, MSI, and Intel, there are a large range of models from these manufacturers, check the specifications and select one that meets your requirements.
I don't know if the Dell has standard mounting holes, I suggest you take the Dell the mounting plate with you when you select your motherboard to see if the mountig holes are suitable.
You may need to upgrade the switch mode power supply as well.

I need to know where to connect the pins for the power switch. It comes on, powers up, but the integrated video isnt working


If the computer powers up, your connection of power switch is OK. Follow these methods, each one at a time, to fix your problem:

A) Unplug the power cord from the computer. Press the power button of the computer (yes, without any electricity source connected!) several times; Reconnect the cable and power-up normally.

B) double-check to see if ALL the rear connections are firmly connected.

C) Open the computer case and look for any blown capacitors (these are electrical tube-shaped component. When they're blown/damaged their top is NOT flat), especially around the CPU area. If you find any - Your motherboard's DEAD. Sorry. If not - proceed...

D) Clean dust! Put special attention to the CPU heatsink and it's fan.

E) Remove, clean and restore the memory (RAM) modules and the graphic adapters (if it's an extension card).

F) If possible, try replacing/testing with another power supply (looks like big metal box with lots of power cords connected to it).

If all that didn't work. you might have faulty hardware. Basically, it might be everything. usually, it's either the power supply (even though it powers up - it can still be defective!), motherboard, graphic adapter or the memory modules.

Good luck!

Addboat,
I have wasted enough time in Dell community for exactly the same problem. Even a link mentioned by Move_n_man above, on 8 Oct. 09 refers to my posting in Dell community. Its nothing but a crashed bios and unfortunately theres none who could tell how to flush the bios and reload fresh bios in the bios chip when computer does not boot.
Dell is in no mood to help! So do the so called experts of the Dell community.

sounds like you need a new motherboard. Try to reset the bios with the jumper (or remove the battery and unplug it) and see if that does anything, if it doesn't start looking for a new mb.

Motherboard Dead


Hi Tom,

there are plenty of basic component overviews in the D500 Service Manual, but I don't believe you're looking for that specifically. What you're looking for is a circuit board schematic, to see the exact paths.

Unfortunately, Dell uses a strictly proprietary wiring scheme, so you'd have to call them directly. Although personally, I'd advise against repairing the board yourself, even with your experience. I think It's quite obvious from the burnt out components you've found that the board was subject to abnormal voltage levels, most likely from a power surge. There's no telling what path the electricity took, and how many components it's damaged. replacing those two inductors (if they are, in fact inductors) could fix the problem, or it couldn't... it's hit or miss at best. It's for this reason that most techs just replace the board instead, soldering it only if the problem is a leaky capacitor or two.

Dead Motherboard?


Testing motherboard components is beyond most users and computer shops these days, especially when it costs more to test than a new board. What you can do is do a visual inspection for physical damage; common items are -broken connectors -capacitors with rounded tops or corrosion at the base -burnt or scorched components or spots on the motherboard -corrosion on the motherboard especially around connectors, solder joints and the CMOS battery. On machines that sit idle for some time when I find physical damage its typically from high humidity, power spikes, dead CMOS batteries and damaged capacitors. Even if I find something physical I will usually replace the motherboard rather than try to fix it and run the real chance of it failing again. More often than not the physical problem we find is usually a symptom and not the actual underlying cause. Since the cost of repair parts is small compared to my labor its more cost efficient for my customers to replace the defective part with a new, warranted part. That minimized the chance of having to pay for my labor again. On the other hand if you want to experiment for the experience then go at it and have fun. Soldering correctly without damaging the part or the board is an definitely an art that takes time to learn.
