If the lights do not come on when the ac adapter is plugged in , it may be as simple as a dead power supply. use a voltmeter and test the output of the adapter at the plug. + into the hole and - on the sleeve exterior. if no reading, or very low replace the adapter. If ok i'd check the ac jack on the laptop. they are fragile and if its loose it will need to be resoldered. Try moving the cord at the jack when plugged in and see if the lights come on.

Is there a power input fuse on a Toshiba Satellite C655D?


no, there is no internal fuse, unfortunately- because this sounds like a dead motherboard. the aftermarket power supply could have been over-volting, or delivering unsteady power- burning the motherboard.

OR the old power supply shorted, and blew the motherboard's power circuitry, and you were just running off battery power when you first got the replacement.

please keep in mind that, at times, the physical power input jack on laptops can also break, or come loose from the motherboard.

Acer laptop switched on light up on switch but no screen display


A blacked-out screen doesn't necessarily indicate a broken monitor. If the computer has run out of charge or is in hibernation or sleep mode,

if the screen is too dark, or if the display cable has come disconnected from the motherboard, the screen may appear black or fail to turn on.

To fix a blacked-out laptop screen, troubleshoot the screen settings, check the LCD connector and see if the computer is awake and receiving power.

Touch the touchpad or move the external mouse to see if the computer is asleep or hibernating. If the computer fails to respond, press "Enter" on the keyboard.

Press the power button if the screen remains black. Confirm that the power indicator light, found at the front of the computer or above the keyboard, is glowing solid green or blue.

Confirm that the power adapter is plugged into the computer and into a wall outlet. Confirm that battery indicator light is glowing solid green or blue.

Hold down the "Fn" key. Press the up-arrow to see if the screen brightness increases. Some computers also use the "F6" or "F7" keys to increase screen brightness.

Hold down the power button for 10 seconds to turn off the laptop. Remove the AC adapter from the computer, close the screen, and then turn the PC over.

Slide the battery latch to eject the battery. Pull the battery out of its compartment.

Turn the computer back over, open the lid, and insert the edge of a flathead screwdriver or other flat, solid object beneath the bezel above the keyboard.

Wedge the edge of the keyboard bezel off of the top cover. Work your way along the edge of the keyboard bezel to loosen it. Pull the bezel off the laptop.

Trace the cable coming from the laptop screen to the connector found beneath the bezel. Reconnect the display cable to the motherboard if the cable has come loose from the connector.
Line up the tabs on the bezel with the slots along the top of the keyboard. Insert the right edge of the bezel into the gap above the keyboard, and then push the bezel back in place.

Turn the computer back on. If the laptop screen is still blacked out, connect an external monitor to the video port on the side of the PC to confirm that the video card isn't defective. If the external monitor works, the LCD screen could be broken.
If the monitor doesn't work, the motherboard or video card might need to be replaced.

hope this helps

Izip electric bike wont start


If the battery cells have been load tested and found OK then You need to trace the output voltage (using a voltmeter) from the battery to the controller to confirm you have voltage at the controller when the power is switched ON. If there is no voltage at the input to the controller then trace the voltage on components between the controller and battery, such as the switch and fuse and all the connectors.
If there is full battery voltage at the input to the controller then suspect the controller is faulty.

There are many things that can cause this type of symptom.
Is it failing on battery only? May need a new battery.
is it failing when plugged into the power adapter?
The adapter input jack will fail over time and need to be replaced.
There is considerable mechanical stress on this part, and It will fail where the jack is soldered to the circuit board.
Internal circuits can fail. Maybe a new laptop will be cheaper than repairing this one.

Ups starts beeping


Is there any indicator lights ON showing the fault condition?
This could indicate that the battery has a low charge. Even if you switch off the mains supply and it switches over to the battery, the UPS may shut down after a short time as the battery power (charge) runs out.
If the battery is more than 3 years old then it may be due for replacement.

Computer will not power up when front panel button is pressed.


Input power has been confirmed? From your home outlet? Or from your computer power supply? I think your computer power supply is bad.

The inverter inside the lcd panel is most likely your problem. Try removing the whole lcd screen from the laptop if you are capable and run it with the external screen to confirm. leave the lcd switch off (this lcd switch above the power button turns the lcd inverter on and off)

Dell latidue D610


The light indicator for the battery is; green-charging, yellow-battery failure, and red-charging system failure. The charging system failure happens when the power management chip fails. The pm chip regulates and controls the power input & usage, allows the machine to switch from AC to battery, and cotrols the charging. This will also cause the problem with the power button not workin or being hard to start. Unfortunately, the motherboard will have to be replaced in order to fix this.
