Try another same PSU, is it still the same!!!
Now try use your PSU to another Laptop, does it works or not !!!

If you can use the other PSU,then the problems is your PSU.Or if still can't use it, even with the brand new ones, then your laptop main board( actually power board inside the laptop) is damaged, you need to find someone or service center to solve this problems, sometimes it just the diode fault.

Hope it works!!!

It sounds like the DC jack inside the laptop is broken. Check the light to see if the battery is charging. If you wiggle the cord where it plugs into the laptop and it sometimes gets a connection, then it is probable that the solder is cracked. It could also be the power adapter itself, or in rare instances, the IC power chip on the motherboard. In any event, it will likely cost you right at $100 to have repaired. If you want help to troubleshoot the problem, give me a call at 864-332-4972 x8003. Steve

Is there a protection mode for this lcd visio tv that can be removed for this tv to come on ?

Hello Donald the first thing I would like to Know what the model number of your TV is. But that's ok if you have a external power supply you could try this .Make Shure your TV is not pug In to the Ac outlet. We are going to see if you have a short or a load on your 12v line. Ok you wont to unplug the 12v source from the power supply board. Fine out what pin is the 12v's. Connect your external power source to that pin, apply the 12v and see if it is drawing to much current. If so check the boards for any very hot items. If you have a problem on the 12v line. This will find the part that is loading it down. This is the old way of finding a load on a power source. I hope this will help some. P.S make Shure there is no AC connect to the TV as you do this test and you have the plug off of the power supply board before using the external power source.

What is the difference between a external hard

External hard drives contain a power supply to operate a standard hard drive in a case. It usually connects to a USB port. Usb drives get their power from the wire that connects it to the USB port A regular internal hard drive gets it's power from the computer's power supply wiring. The data cable is either a flat ribbon cable or a 6 pin cable that connects directly to the mother board.

What is a PSU?

psu or PSU is an abbreviation standing for Power Supply Unit. This is often a device (box) which converts your mains supply (input) into the voltages (with currents) which are correct for your device (eg your printer). This may be inside the case (eg in a computer) where you cannot see it, and you just plug in the mains lead to the device, or an external box which has two (or more) cables or connections to/from it, one or more of which is connected to your devise (eg a laptop computer). Printers may have either depending on the model. Every model of device has its own model of PSU (or family of suitable PSUs). Just any PSU will not do and might damage your device

Connect to external power, the indicator light is on. Power switch does not turn the system on. What is the most likely source of the problem? Motherboard?

Try... take the battery out, take the charger out.. hold down the power button for 10 seconds... plug in the battery and the charger, turn on... worth a try - fingers crossed
if not then yeah its possibly the Motherboard or PSU

My external harddrive keeps restarting...what would cause this to happen?

being an external hard the problem could be with the power supply unit PSU

Test your PSU or replace it if your power supply units fan is not working your PSU is faulty

One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect/ boot up

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your ((motherboard to your hard drive)) make sure they have a secure connection and are not faulty or just replace them there probably old and faulty

make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty or just replace them they are probably old and faulty ?
hope this helps

The power supply light is on Acer 2300

Ok all PSU, these days are whats called Switchmode technology, now these PSU, are designed to shut down if they "See" an overload, or short circuit... When the PC is connected to the PSU, it draws current, IF that current is over a certain limit it will also shut down... Sometimes that will happen also when the PSU is faulty.. that voltage measured when NOT connected, is called the "Open Circuit" voltage and can be misleading, as really it must be measured under load, as it is called. So, if when, you connect the PSU's LED goes OUT, then either the PC, is faulty, OR the PSU is faulty, the only real way to tell is by substitution. Also check where the lead enters the Plug, this will sometimes cause problems. A PC should work ONLY on a PSU, so remove battery and check, if still no go, then, suspect the PSU, if it does, may be the battery. OR the internal power conditioning circuitry.

Can you put a cd in this laptop

Need more details, as to laptop model. But if it is a Full sized NOTEBOOK, YES you probably can,,, if it is a "NETBOOK",, then no, you can't. If it is a netbook, you can get a USB powered EXTERNAL CD drive which will connect to a USB port and work that way.

Hope this helps, if you need more info, or have more info to give get back to me,, I CAN solve this problem!!

External hard drive

500Gb Lacie D2 Quadra with the same problem of flashing led and not mounting on the desktop (Mac G4 Mirror), traced to the power supply (57w) going down on power, both 12v and 5v supplies are available but the main power to run the drive drops to below an adequate output, hence the clicking and whirring evident from the drive with simultaneous flashing led.

Testing with another Lacie power supply (250Gb D2) this time a 34w unit got the drive up and running, however, and this is the reason for this post, this lower power PSU failed a week later whilst waiting for a warranty replacement from Lacie (5 weeks and still waiting for the new PSU from them. they have no stock)

Message for all Lacie D2 users, check the power supplies first, test with another Lacie PSU, do not run the drive on a lower rating (34w) PSU it will fry it and leave you with another failed power supply.

If you are in a tight spot use the temporary power supply to move your data to another drive and get the correct 57w power supply before running the drive again.

Don't do as I did assume any Lacie power supply will run any Lacie hard drive, they won't, fortunately I had a second back up, but am 2 drives down and no new PSU's available to buy anywhere.

Try and purchase another spare 57w power supply, something all D2 users should do for long term security, as these do not seem to be very reliable and getting warranty support from Lacie on these is currently impossible.

The lack of 57w power supplies from Lacie and its distributors across the world is surely a warning to be noted!!!!!!

Buyers beware!
