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.

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.

The battery of my Dell Latitude D600 is not charging fully. It only runs for 10 minutes when fully charged. Moreover, the battery indicator flashes 4 times red and one time green. Is it the battery problem...


That sounds like a bad battery. Be sure not to leave charger plugged into your computer while not plugged into power or the power switched off. That will really kill your weak battery and then you won't have 10 minutes. You can live okay with a battery like yours but if you ever need to replace ram or do a serious BIOS update the bad battery will not alallow it.

My dell d600 is not charging what is the solution and it always flash red light when it is plug to power


That means either the battery is no longer good anymore or the laptop is unable to charge and/or recognize the battery. Try cleaning the contacts of both the battery and the laptop when everything is unplugged and powered off with alcohol and a q-tip. But usually if a laptop is not charging the battery then most likely you will need a new one

Intel Speedstep is throttling the processor to save power. You likely have to adjust the power management settings to ALWAYS ON to keep the processor from throttling down.

Battery


AC only will not effect speed what so ever, running on battery only does. Battery only decreases the speed, it's the speed step technology to make the battery last longer. If a fail safe in the battery engages, it could effect the machine's performance, so if you see any decrease in the performance, remove the bad battery and run without it.

Dell D600 laptop


If you've tested the power supply and battery, then the only thing left is a motherboard component. The problem will either be with the DC jack or the power management system. First check to see if the jack is loose or noticeably broken. If not, then it's going to be the power management chip. The pm chip controls and regulates the power input, switching from AC to battery, and the charging. With the pm chip, the motherboard will need to be replaced.
