There is no overload circuit on these. This probably did in the board, however, it may have just got the processor. Start there.

Can i use any charger on s505


The Toshiba Satellite 5205 series of Notebook PC, and the S505 series model; uses an AC adapter (Charger) that produces 15 Volts DC.

http://www.sparepartswarehouse.com/Toshiba,Satellite,5205,PS520U-31P1RV,Laptop,AC-Adapters.aspx

You will see AC adapters sold that show 15 to 24 Volts. (DC)

http://www.duracelldirect.com/toshiba_satellite-5205-s505_ac-adapters_laptop_ac-b20h.aspx

This is because the AC adapter (Charger) has PFC.
Power Factor Correction,

Also I see it is just a two pin AC adapter plug, to laptop.
Center hole is Positive, outer metal cylindrical metal shell is Negative.

Go for 75 Watts or higher though, and not a 65 Watt model.

[ On the case of the AC adapter;
Input: 100 ~ 240 VAC 50-60Hz

Means it can use from 100 to 240 Volts AC, and either 50 or 60 Hertz.

Output: 15VDC 6A

Means 15 Volts DC at 6 Amp's. (Amperes)

Watch the outside dimension of the cylindrical part, and the center hole dimension. Outside cylinder may be correct, but center hole may be too small. Or vice-versa.

I have a new HP mini and last night my husband used it for just a minute but turned it off by clicking on "shut down" from the menu. Now it does not come on at all. How to I turn it back on? ...


There should be a power button on the laptop somewhere, just push it and the machine should boot back up no problem. The menu option is the normal method for shutting down so it should not cause any problems. Just make sure your power cord is plugged in in case your battery is dead.

Good luck ad please comment back if this was helpful.

My laptop wont turn on, even when the power cord is plugged in. i tested the power cord with a multi meter and the cord has power


Hi,

Have you tried removing your battery for a minute then plug it in again?
Check also your charger if it has a voltage output using your multi-meter. the expected voltage you will read is indicated on your chargers name tag in DC volts (observe polarity).

When you press the power button does anything happens to your laptop or nothing happens at all even indicator lights?

Don't forget to rate me...
Thanks..

regards,
John

My charger won't charge. Computer detects plugged in but no charge


This is usually caused by an old or defective battery or possibly the power supply is a few volts too low to activate the charge indicator. It might be charging but not letting you know.
Try to run it off battery for a while (look at the battery life) and then plug it back to for a while then unplug it again to see if the battery life if higher than before.
To check the power supply you will need a volt meter that can read at least 20 vdc (most power supplies are 19 vdc). Put one lead of the meter on the inside of the plug that goes into the computer and the other pin on the outer silver part while the power supply is plugged into the wall outlet. You should read close to what the Output Voltage on the power supply says which should be on the sticker on the back or side of the black box part of the power supply.

Laptop won't power up without battery, needs 135W adapter


The ASUS power adapter is below spec and it may damage the adapter because the HP is drawing 45 W more power than it can deliver and will cause it to overheat.
The 17" HP requires 18.5 or 19 volts depending upon the model of the HP laptop (check the power requirements on the label on the bottom of the laptop). If the ASUS adapter doesn't deliver this voltage, it most likely won't power up the HP laptop.
Use the power supply/adapter from the other 15" HP. If this HP's adapter has a voltage output of 19 volts and the 17" laptop requires 18.5 volts, don't worry a voltage difference of 0.5 volts, the only problem is whether the power plug will fit into the power socket of the 17" HP laptop.

No power to the laptop


You have a malfunctioning powere supply. To test the power supply, you can use an amp meter to check how many amps it puts out to see if it is working ok. Or if you can simply connect it to another laptop with same model if available. These power supply have an output of 19 volts by the way. You can also use another power supply if avialable to see if its indeed the power supply.
