Won't turn on - dead dead dead

Checked e-mail this morning. Worked OK. two hours later nothing! The AC adaptor measures 19vdc output (not under load, i.e. unplugged). Little green light(s) on front DON'T light up. For a long time, the ON button has had to be pressed only on the front right corner and pressed rather hard to turn it on. The laptop doesn't do anything using battery either. PLEASE HELP SOON!! Thank you

Re: Won't turn on - dead dead dead

Hi, This sounds like the power supply circuitry inside the notebook. 1. AC Adaptor - OK but if connected to the mains and plug to the laptop, there should be an indicator in the laptop that it is so, per your post none; 2. Battery - doesn't power the laptop; 3. Power Button - press hard and long, not normal. Guess that leaves only the laptop itself. This would involve opening the unit and diagnosing the power supply section which includes the jack, reverse protection diode, smc fuse(s), charging components, power button and others. Probably you should seek the services of a qualified professional though I am getting the impression that you are technically adept likewise. Hope this be of some help/idea. Post back how things are or should you need further information. good luck and kind regards.

First you shoult remove the battery (it could be short circuited) then try powering up, if it's not working check the AC adaptor with a multimeter to verify voltage (compare with what it is ritten on the AC adaptor) last thing you should remove everything you can (RAM, HARD DRIVE, NIC's, CD ROM, etc...) than try powering up again if it power's up than put back ONE DEVICE/MODULE AT A TIME TO TARGET THE FAULTY DEVICE. if nothing worked i'm sorry it's dead.

Good luck!

My acer one tries to boot but when the screens is abuot to turn on it shuts off

you may be trying to power it up with a faulty ac adaptor---it's trying to boot up with a battery that is just about dead. test the adaptor for the proper output

Totally dead, replaced ac adaptor, which was dead too, did not help. still dead.

Hello, I am thinking that your battery needs to be replaced as well. Possibly because of the stress it took from your ac adapter issues. So, to check to see if the issue at hand is now your battery... 1) UNPLUG THE AC ADAPTER FROM THE LAPTOP. 2) REMOVE THE BATTERY. 3) PLUG THE AC ADAPTER BACK INTO THE LAPTOP 4) TURN IT ON.
If the battery was now the issue, your laptop should have turned on at this point.. If it did NOT turn on, then there is a different issue that we should troubleshoot. Let Me Know, ok?

Toshiba PA2450U AC Adaptor - Dead. Any common faults with these?

Toshiba AC adaptors DO fail, as do those of other laptops.Probably why Ebay has so many listed. You can look there, or numerous online stores, and easily find a replacement for a lot less then Toshiba, and should be able to find one with a higher current (Amps) output too, which will carry the load better..

Gateway M-6750 wont turn on suddenly.

Sounds like the motherboard may have gone bad on you. If your ac adaptor has a light on it, make sure it still has the light still illuminates when you plug it into a wall outlet. If it doesn't light up then it could be the adaptor but since you tried both just the battery and just the ac adaptor that would tell me the motherboard is bad. The only other option would be to resolder the dc jack on the motherboard back in place. It could be that the solder joints underneath the dc jack have cracks in them.

Ac power doesnt work only in battery mode,adaptor output is ok

sounds like the power connector (where you plug into pc) is going bad. try twisting / wiggling connector. pause for a few seconds between twists to give circuitry chance to reconize power input. sometimes there is a green led that will light up when power adaptor is inserted. you can use that as a reference.

Won't turn on - no ac power not with battery no indicator lights

Hi, My Name is Henry. I am one of the technicians here.

It may be that the battery has gone totally flat and needs boosting to start charging or simply that its dead. Another possibility is your ac adaptor charge. You need to check to see that that is working.

If still not working. I suggest you invite a Laptop repair technician.

Please do not forget to rate my solutions to you.

Athlon HP won't power - NOT AC adaptor or DC jack on board.

There are small rectangular surface mounted fuses inside on the motherboard that may be open. These will be small and white with the circuit designation Fxxx written on the board. Look for these first and check them.

Update this with what you find.

When operating from line power, there is normally two sections in play; the first is the part to which AC is attached, the second is internal to the laptop and manages the DC used by the computer, and presents a controlled charge current to the battery pack.
The external part is pretty easy to check with any kind of multimeter which can be had for well under $20 US and has functions useful for other purposes at home. I think everyone should have one.
If the adaptor is the type with a box that plugs into the AC outlet, it will have a rating stamped or molded into the wall-facing side and will read something like "12 VDC - 1000 mA"  Obviously the values could be different but this will give you a guide if you measure the output of the module at the end of the connection cable. This voltage value can vary by a bunch; one rated at 12 volts may measure 14-15-17 volts since these are normally not regulated and will always measure high when not supplying current. The regulation is done by the internal part, often a separate board.
If you measure a voltage at or above the rating of the module, it is probably OK and that means that the internal regulator is defective. The module (adaptor) can be bought from a variety of sources and ideally, you should get a Dell part or exact replacement since the 'universal' types . . . ain't.  They may be offered with a interchangeable plug and a polarity reversal switch or plug and there is some risk in attaching one to your system unless you have a bit of technical understanding and, that multimeter.  Shop for price though, even on the 'original' Dell part or an exact replacement, price can vary 3:1.
