Ac power adapters differnt ampage

I'm trying to get a replacement for my ac adapter for my laptop. I have a toughbook cf-w2 and the ac adapter cord to recharge the battery has a short in it and wont work. I can't seem to find an exact replacement for the adapter. the computer calls for one with 16V at 2.5 amps. the closest adapter i can find is one with 16 V at 3.75 amps. Will this adapter work or do i need something with 2.5 amps.
Thanks
Darrell

SOURCE: Dell Inspiron 1501 AC Adapter error message

The Dell 1501 ac adapter (possibly other Dell’s as well) has been known to be problematic because of its lack of a plug to jack secure fit. You will notice that the plug can all too easily be pulled from the jack, as opposed to other systems where the plug fits more securely onto the jack. The plug and jack combination is poorly designed so that over time, the plug will come unseated depending on how much movement the machine is subjected to. This will result in power error messages or outright power-up failure. So before assuming you have a faulty adapter, make sure that it is not just a loose plug that is causing the problem. If you look inside the jack, you will notice that there is a 3mm region of non-conductive material nearest the surface of the jack. Use a strip of standard electrical tape 3mm wide and long enough and wrap it around the base of the plug (you may need more than one layer of tape to get a good fit). I have used this method to secure my plug and it has served me well. If the tape comes undone over time, just simply replace it. A more “elegant” method would be to use an “O” ring of the appropriate size (about 6mm) around the base of the plug in lieu of the tape.

SOURCE: Gateway laptop AC adapter not working

Fixable? Maybe
Sounds like a problem with the power jack on the Motherboard. If so, it is possible to remove the board and replace the jack but this requires soldering skills and is probably not something the average person would want to try.

You might try another adapter to be sure but if it is a motherboard problem the best solution is probably to junk it and buy a new laptop.

Select product support on the front page, then go to parts.

My puppy chewed through the cord for my a/c adapter, I just took the speakers into Circuit City, and they found me a workable replacement (the replacement isn't BOSE, but it works just fine).  Hope that helps!

Battery light is blinking red and will not charge


Hi,

Welcome to Fixya! If the battery light is blinking red,that indicates low power, there's a possibility that the problem is with the AC adapter, or the battery or maybe the DC port itself, 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...

2. Battery will not charge in the laptop.
3. Laptop runs fine off a charged battery.
4. With the AC Adapter connected the laptop appears to be dead.
No power LED or battery charge LED activity.
5. Laptop randomly powers off without any warning.

If your laptop is out of warranty, then you can fix the problem by re-soldering DC-IN jack on the system board. If it

I can turn it on but the screen will not come on.


Remove the battery and ac adapter. Press power button for 10 seconds then connect the ac adapter. Turn on the system. If this didn't work. You need to go to a service center to test your motherboard.

Laptop will not come back on


Take the battery out of the laptop and only hook up the AC Adapter, if it turns on then that means the battery is shorted out and would need to be replaced.

If the laptop still doesn't turn on with just the AC Adapter, look to see if there is a LED Light on the AC Adapter, if the light isn't on when the adapter is plugged in then that means the adapter is bad and would need to be replaced.

If there is no LED indicator on your laptop then try another AC Adapter, if the laptop still doesn't turn on then that means your motherboard is bad and would need to be replaced.

On AC Power


It does sound like a power cord problem. You can test it by getting a digital mulimeter and checking to see if there is 19.5 Volts DC power on the contact points of the barrel plug that goes into the laptop.
