Computer won't power up

The AC power supply does work. I checked it with my DVM and it puts out 12.5 VAC. When I plug the supply into the computer the left most LED on the front face, the one with the power cord symbol turns green and then it changes to a flashing yellow.

Re: Computer won't power up

I checked the toshiba site for information on your laptop, but there is nothing on your model.

I would say there will be something wrong with the power supply internally. I'm not too sure about laptops, but I think this is a small problem. You should take it to a repair guy and just get a preliminary report, before you spend money.

Laptops are quite cheap these days, so your decision is whether to repair or to repurchase a new one.

Re: Computer won't power up

First check the voltage on the batery and read the tag from the power suply make sure the voltage from the tag is the same to the output voltage because it looks like there is not enough voltage to charge the batery and does not work with the computer either

Won"t power up. If I hold the power button down an icon on the lower right flashes on but nothing else happens.


It is unfortunate that the computer is not turning on. Request you to try following the below steps which might help:
    (1)Turn off the computer.
    (2)Remove all the external peripherals like AC Adaptor, flash drives, battery, etc.
    (3)Press and hold the power button for 30sec which releases the static on the computer (if any)
    (4)Put back the battery and plug in the AC Adaptor.
    (5)Let the computer charge for some time.
    (6)Try turning on the computer. If the computer doesn't turn on then check if the computer gives any series of beeps or if there are any diagnostics LEDs on it.

    Thanks and Regards.

Computer won't turn on help!!!!

Unplug, remove the battery, plug in, try to turn on. If that fails, try another AC/DC cord/charger with the EXACT same power specs. Has the AC jack been damaged due to pulling on the cord? Damage due to Power surges? Do you leave it plugged in while not in use a lot?

Hp computer tower will not go on

Would that be an LED (Light Emitting Diode), blinking on the back of the Power Supply?

If so, instead of being an LED that indicates the Power Supply has power to it, it has now turned into a diagnostic LED (Light), and is telling you the Power Supply is bad.

Do you have an economical multimeter, so I can guide you in testing the 3 low DC Voltages; that come out of the Power Supply?
An economical multimeter can be purchased for as little as $5 to $12.
I have seen them on checkout aisle racks, in major discount stores.

The dangerous high AC voltage, is kept contained within the metal case of the Power Supply.
(100 to 240 Volts depending on what country you are in)

The Power Supply is a Converter.
It converts the high AC voltage into 3 low DC Voltages;
3.3 Volts, 5 Volts, and 12 Volts.
In comparison two D cell flashlight batteries produce 3 Volts DC.

Use a KNOWN to be good, Compatible power supply; for a temporary test unit.

{"Honey, I'm going to borrow the Power Supply out of your computer.
I'll put it back when I'm done."
"What? I'll be sleeping on the couch? K"} (Lol!)

Also, is the inside of the computer dirty?
(Computer Unplugged from power, Anti-Static Procedures FOLLOWED)

Let's start here......

Also, what is the Product Number?
Back of computer tower, white Service Tag.
P/N = Product Number

My hp mini 1000 will not turn on. When I plug it in the light on the side will not say it is charging. It will not charge.


Here are some steps that can help you resolve the issue.

First, try removing the ac adapater and the battery and press and hold the power button for about 10-15 secs to remove the flea power. Then try to deattached the power cable and the power brick and attach it again properly, plug it to the computer without the battery and try to turn on the computer. If still the same problem try a good known power socket, if your using power strip try to plug it directly to the wall socket. If nothing works, try a good known ac adapter, or try you ac adapter to a good known working computer. If a good known ac adapter didnt work, contact HP as this is a power supply issue on the computer (power supply are mostly attached to motherboard for portables) contact HP to check your warranty and have it serviced. If the good known ac adapter works, contact HP to check the warranty and have the AC adapater replace or simply replace the ac adapter.

I hope this will be able to help you.

Thank you for choosing Fixya.

Have an Acer Aspire 5920G that is dead. The power supply seems OK with the green light on and ~19 VDC on the DVM when checked. no power light on computer when plugged in, with or without battery.


It is possible that there is a problem with the connection from your power supply going to the main board of your laptop.
This is rather a technical problem and my best recommendation is to bring your laptop to a technician and have them check it.

Hope it helps!

Try remove the battery and unplug it from the AC. Hold down the power button for 35-45secs. plug AC back and see if you can power it back on. If not, the motherboard is shot.

Plugged in Laptop won't turn on.

Hi there, your computer may have a power problem you should first plug the AC power adopter into a different wall outlet, and check the light which indicate if the computer receiving power if the problem still exist you should check the AC power adopter to see if it is working. You can do so by using it on another computer just like yours,and should also try another AC power adopter on your computer just like the present one,if your computer work this mean the problem was the adopter.If the problem still exist then it may be the power supply or the motherboard has a fault and need to be replace

Toshiba satelitte adapter went bad ordered new one it wont work

If the old one works you have another power supply or wrong one.
Check the properties of your power supply.

Related to your issue you also may consider this:

1.- Computer AC / DC cable is bad not allowing the computer battery to charge.
2.- Battery is bad.
3.- Battery charger board is bad.

1.- Computer AC / DC cable is bad not allowing the computer battery to charge
Verify that the AC and or DC cable is not bad by testing the computer only with the power plug connected and the battery out of the laptop.
2.- Battery is bad
It is possible that if the power plug is good that the computer battery is bad. Leave the computer connected to the power with the battery connected in the computer for at least one hour; if the battery does not charge, consider having the battery and/or the laptop serviced or repaired.
If the computer and/or battery is not in warranty consider just replacing the battery as it is very likely that it is just a bad battery.
3.- Battery charger board is bad
If the battery has been replaced or an alternate battery from an alternate identical laptop does not work in the computer, it is likely that the power or charger board within the laptop is bad. It is recommended that the laptop be serviced or repaired.
