Dell d600 power issues

My dell D600 cannot recognize the power supply, so it only runs at a safe speed (600Mhz) and it won't charge the battery.

Re: dell d600 power issues

The problem is in either the power lead from your powerpack or in the connector on the motherboard itself.
In this case I would say it's in the powerpack.

Dell use a smart power supply system that talks to the laptop to say if it is a genuine part or not.

If you look at the plug you will notice something strange about it.
There are actually 3 layers in there (well sort of)
You have the outer layer, then inside you will see a pin. There is another layer that is wrapping around the inside of the plug that is a mirror of the outer layer.

The wire that connects to the centre pin is not power, but the smart pin. The wire can easily break off that pin and just sit inside the cable.

Try it with a known good adaptor, or just get another one.

When I boot up my desk top with monitor E197 FP LCD stays black takes a few times to go


This is a common problem with the E197 units. The problem is caused by a failure of the filter capacitors on the power supply board, they are not holding a charge like they should and it takes several power cycles to get them charged up so the monitor turns on. The E197 uses the same power supply that the E177 uses. Here is a link to a repair guide for the E177 with video disassembly and repair instructions that will help you get your monitor going again.

I think you answered your own question--the computer works well with other monitors, but not this one.
I would suspect that this one is bad.
You might try to do this: Start the computer in safe mode and see if your monitor is reacting to video settings that are beyond it's capability (although if this is the case it should tell you it's out of range).
If it works in safe mode, try resetting the resolution to see if it will work with the new monitor (I seriously doubt that this is the problem).

Once before I had a similar Toshiba come into the shop. Try turning the unit on without the battery installed and on the good Toshiba charger. The computer batteries have a minimal current level and once power has gone below this level they will cause all kinds of problems. If the Toshiba now works, you're home free - just replace the battery. If it doesn't work then it will have to see a reputable repair person who can troubleshoot chip issues. I've seen these clone power supplies do all kinds of things to computers.

My Kogi L7EH-TA monitor will not function when hooked to my new Dell Inspiron 537.

Do you get a No Signal on the monitor?

IF so, the problem is in your computer, or you have a bad monitor cable. (Cable from monitor to computer)

Try the monitor on a known working computer, and use that working computer's monitor cable.

Monitor works?

Okay now use the monitor cable from the Dell Inspiron 537.
Monitor works?

Problem is in the computer.

Monitor doesn't work?
Problem is the monitor cable. They do go bad.

Problem is the computer? Check to see how dirty the computer is inside. Unplug the computer from power, open the computer case.

DO NOT reach inside, and touch any components, even to clean, until you have touched the metal frame of the computer case. You are just looking for now.

[ Your body carries Static electricity. Static will fry out the hardware components inside a computer.

Static will do it in a flash, and you won't see it, or feel it!
Computer unplugged from power, you're safe. Touch the metal frame of the open computer case, your computer is safe ]

If the inside of the computer is dirty, so is the power supply. The case fan/s draw air into the computer, and push the air through the computer case.

The power supply fan draws air through the computer, and pushes the air out of the back of the
Anything that goes through the computer, also goes through the power supply.

Dust, Dirt,. Hair, Lint, Carpet Deodorizer, you name it, can be drawn in. (Sometimes, spiders make webs inside!)

Inside the Dell Inspiron 537 Desktop PC, is a processor with a Heatsink on it, and a Fan on top of the heatsink.

The Heatsink is a square looking device, that has fins on the top.
The bottom is flat, and is attached to the top of the Processor's case.
The heatsink absorbs the heat of the processor, by being in close relation to it, and the fins radiate the heat up, and out.

(What an average Heatsink, and Fan combo look like,

There is also Thermal Paste, in-between the top of the Processor case, and bottom of the Heatsink)

The fan attached to the top of the Heatsink b-lows the heat away.
If the fins become clogged, and the blades of the fan, the processor heats up.

When the processor becomes too hot, it turns off.
This is a Fail Safe feature that is built-in. BIOS turns the Processor off.

During this, the Processor has been calling for more power, due to the heat.
The power supply tries to keep up.

The power supply has Heatsinks inside it, also. Plus a fan, to draw air across the components inside the power supply.
This is the power supply's cooling system.

Once the fins of the heatsinks become clogged, and the fan blades, the cooling efficiency drops tremendously.

The power supply heats up.
Again, Heat = Wasted Energy.

The power supply tries to put more, and more power out, until eventually the components inside the power supply fail.

Power supply failure is a main cause of computer failure.

The laptop starts up with a pink hue

Make sure the LCD is completely attached to the system board. I've had them come partially out and cause this. If this doesn't help, your LCD and/or inverter could be going bad.

Input not supported

This is a communication issue starting with your docking station. Sometimes updated drivers are neede to insure that a device works with all devices between your pc and your laptop. Check on Dells website to see if there is an updated driver. In additon you may want to run the cd that came with your monitor, they are always shipped with a cd with drivers on them!
