AC adapter cut out ? Home docking station

check with multimeter on Volts DC if there is any voltage on Adapter pin, if there is no voltage then you need new adapter

Hi,


Im very sorry to hear that, please follow these simple steps for you to be able to isolate the exact problem.


1. Removed the battery.
2. Connect the laptop directly to the power outlet without using the battery just for the meantime.
3. Turn on the laptop. If the laptop is able to power on, that means that the AC adapter is working fine as well as the DC port. If the laptop is not able to turn on, it maybe the AC adapter itself or the DC port.
4. Try to use another AC adapter if possible, make sure that that AC adapter is working fine. If the laptop is still not turning on, the problem is with the DC port itself. In that case, you will need to replaced the Motherboard itself.


Hope this will help...Thank you for using Fixya...

sounds like the situation is with the AC adapter detection. try to restore your BIOS defaults and update BIOS if applicable. Test another AC adapter. If that fails, most likely, this is with the motherboard. You may either get a new board, or just continue to charge it using the docking station.

The issue might be due to presents of static charges, hence request you to power drain the ntoebook.

Power Drain:

1. Unplug the AC adapter from the notebook PC and remove from any port replicator or docking station.
2. Remove the battery from the notebook battery compartment.
3. Press and hold down the power button for about 20 seconds.

NOTE:
Holding down the power button while the computer is turned off drains any residual charge in the capacitors.

1. Insert the battery and plug the AC adapter back into the notebook PC.
2. Press the power button to turn the notebook PC back on.
3. Use the arrow keys to highlight Start Windows Normally , if it is not already highlighted, and then press the enter key.

if persists, recommend you to take the notebook to technician for oniste diagnosis.

There's a "slide-away" coverv on the bottom of the laptop, where the docking-station's adapter would connect. Manually slide the cover, and inspect to ensure that there's nothing stuck there that is "tricking" the laptop into claiming that it is docked.

I just want to know, removing battery and docking station, and just use the ac adapter alone still no power on the laptop? If yes please replace the motherboard.

Remove Any Docking Stations or Port Replicators From the Computer Note: Docking stations and port replicators are optional equipment. If you are unsure if you have a docking solution attached to your computer, refer to Table 1 and Table 2 for examples. To remove the docking station or port replicator, perform the following steps: Shut down the computer. Remove the docking station: Universal Docking Stations: Disconnect the docking station's USB cable from the computer. D/Port or D/Dock: Remove any cable locks from the security slot on the right side of the docking station. Move the slide lock forward to the unlocked position. Press the Eject button and lift the computer from the docking station. C/Port II or C/Dock II: Remove any cable locks from the security slot on the left side of the docking station. Pull the locking lever forward until it stops to eject the computer, then slide the computer out of the docking station. Dell manufactures the following docking stations and port replicators (Table 1): D-series DocksC-series DocksSpecialty Docks D/PortLatitude? C/Port IIMedia Bases D/DockLatitude? C/Dock IIInspiron? Advanced Port Replicator Table 1: Dell Docking Stations (Click an image to enlarge it) Universal docking solutions are also available from third-party manufacturers including, but not limited to, the products below (Table 2): TargusKensingtonBelkin Table 2: Universal Docking Solutions (Click an image to enlarge it) Disconnect All Peripherals from the Computer Remove all external connections from the computer. This includes but is not limited to the following devices: docking station or advanced port replicator keyboard mouse speakers or microphone printers scanners USB or 1394 devices palm pilots zip drives secondary battery Plug the AC Power Adapter into the Laptop Computer Remove the battery from the computer. Connect the AC adapter directly to the computer Verify That the AC Power Adapter Has a Solid Green or Blue Light Verify the AC power adapter displays a solid green or blue light. Older Latitude? C Series laptop computer AC adapters may not have a light. The new E series power adapter indicator light is either a blue ring or a blue dot and is located at the tip, on the DC connector, not on the power brick itself (Figure 1). Figure 1: E Series Power Adapter Indicator Light Location Numbers reference image above: E Series Power Adapter Indicator - Blue Ring E Series Power Adapter Indicator - Blue Dot D series power adapters have a green lights located on the power brick (Figure2). Figure 2: D Series Powed Adapter Indicator Light Location Numbers reference image above: D Series Power Adapter Power Brick D Series Power Adapter Power Indicator Light Shut Down the System If the computer currently is turned ON, running on the battery, shut down the system: 1 Click Start. 2 Click Shutdown. 3 Choose Shutdown from the menu. 4 Click OK. 5 Allow the system to power off. Plug the AC Adapter into a Known-Good Wall Outlet Verify the wall outlet is known-good by testing it with another device, such as a lamp. Confirm there are no power strips, surge protectors, or uninterruptible power supplies (UPS devices) connected to the power cable. UPS devices provide temporary power for a computer when there is no electricity available from the wall socket, such as during a power outage. Plug the power cable into the known-good wall outlet. Power up the system. Replace the MiniPCI Door, Rubber Feet, and System Motherboard

If the docking station charging doesn't work either and your battery is ok you have lost voltage regulator (it prevents overcharging of battery) Take the battery to a battery plus store and they can check it..

This seems to be a shot in the charging circuit of the motherboard. If in warranty call Dell hardware supoprt and they will do the needful in warranty. If the warranty is out try a local technician and maybe they can repair the board.

Try this, with laptop removed from docking unit:

1. Press and hold the laptop power button down, for 10 seconds.
2. Now remove the battery
3. Repeat step one above
4. Let the laptop sit for 10 minutes.
5. Reinstall the battery
6. Make sure docking station is unplugged, and insert laptop into docking station.
7. Plug in power supply (to dock)
8. Start the laptop.
9. IF IT STARTS, let it run a while to see if the battery is charging
10. Remove it from the dock and repeat steps 1-5 above and then go directly to 8 (start without connecting dock).

CONCLUSIONS: If the laptop started in the dock on step 9 but not 10 (only on battery), your battery or power regulator circuit may be damaged. However, if it starts in step 10 but not step 9, your docking station -or its AC power supply may be damaged Let me know how this comes out, please.
