    The green light is showing on the adaptor but the LED's are not doing anything. It is a brand new Toshiba adapator. I am wonering if there could be anything wrong with the laptop on/off switch but don't know how to check it. There is no power in the battery.

Hi Doc, How have you determined that the A/C adaptor is working correctly? When you plug the adaptor into the laptop do any of the LEDs do anything? What about the battery, can you run off it?

When you plug the power cord in the lap top does not even power up there is nothing


Your power supply is either faulty or your computers power supply area is faulty, if you have a light on the power supply usually green, you can tell that way if your power supply is working, the other way to tell would be a multi meter checking dc voltage from the power supply's end, if you get around 13-14.5 volts somewhere in that area, then it is supplying voltage and is okay, which would mean it would be your power supply in the computer on the motherboard is faulty, which needs serviced by the company if under warranty or computer tech, if your power supply is all the way in and plugged in the laptop, it's usually one of those two issues, it can still work on battery and sometimes it wont if it is the computer, i would first suspect the power supply itself first, and check it while plugged in , even plug it into another outlet just to rule that out. if the power supply is bad and you replace it, the computer should work fine, unless there is internal damage in the computer. Hope this helps.

My laptop acer extensa 4420 5239 will not power on.The battery light goes green if i charged it fine. It seems that the switch is having a problem or might be the power supply. how would i know?. please...


Probably there is a problem with your battery charger or power supply. It might not charging your battery. The only reason why the laptop would not power on if there is no power supply coming in, either from a battery or a direct connection from the power supply. You can check your battery charger or power supply using a multimeter. Check if there is a voltage reading coming from your charger.

We hava a viewsonic 1912w-4, model VSS10866 and


I'm assuming the computer is coming on alright. Double check this by putting another monitor in place of the Viewsonic. If the old monitor displays everything like normal then something has failed in the internal power supply. Take the Viewsonic to a reputable repair person or check my website www.micromendllc.com.

Charger was plugged in and working fine, went into


OK unplug power supply from back of laptop, remove battery, insert power supply, if NO light, on laptop, power supply is broken..Replace. IF it is OK, hold power button ON for a while, or until, the PC starts, if/when it starts, shutdown, with power ON key, and then take out power supply, replace battery, replace power supply, turn laptop on, now should be OK.

Power issues on HP DV1000


It is possible you have two dud batteries. Recharageable batteries have a limited life, they have a finite number of charge and discharge cycles.
With the battery removed and only the power supply connected and the laptop powered up, when you touch the connector on the laptop and the laptop does not shut down then the laptop connector is OK.

If you can verify your new battery is OK the the fault could be the power supply adapter, if may not produce enought current to run and charge the battery. Try charging the battery overnight by turning off the laptop and leaving on the mains t charge. Borrow a mains adapter and test it on your computer.

You can also check the BIOS setting for power management, ie. hibernate, low power shut down etc.

Laptop will not power on at all.


Don't know what you have for a laptop, so will have to give you a generic process, here. Power down. Remove hard drive, remove cd reader and/or floppy drive. Remove memory cards. Replace only 1 memory card in the main slot (probably marked as slot 1). Try to power it back up and let us know what happens.
Thanks!
