Question about Computers & Internet
Seem like battery or power supply problem,
as you think that there is only one laptop in the world - yours - you are mistaken...
for help you need to provide manufacturer and model and in case of computers - operating system as well...

There's evidently a short on the laptop's motherboard. Unless it's something obvious that can be repaired easily (and it'll still cost a lot for the labor to take the laptop completely apart and put it back together), you're going to have to get the motherboard replaced (expensive)or get a new laptop - depending on which seems more cost effective to you.
In any event, contact Dell.

SOURCE: i have a Toshiba PSAF3U-0NR00V,
The most common reasons for power issues are the battery, power jack and power adapter/cord.
Power off and remove the battery. If the laptop powers on with just the adapter connected, your battery is faulty.
If you move/wiggle the power adapter at the point where it connects to the laptop, and the power goes off and on, the power jack is the problem.
The power jack is inside the laptop and either needs soldering or replacement. If a power jack problem, it should be addressed by someone knowledgeable.
If no change, the power adapter is probably faulty and needs replacement.
Hope this helps.

SOURCE: i have a advent 7201.it will not come on on its own and it will not come on when the charger is plugged in.the green light is on on the charger but no power on the laptop.could it be the battery or th
Use a multimeter.
An economical unit can be purchased for as little as $8 to $12.
Available in a multitude of stores. An auto parts store is but one example.
Analog or digital is fine.
The Red probe lead is the Positive lead. Plug it into the hole with the red circle, on the multimeter.
The Black probe lead is the Negative lead. Plug it into the hole circled with a black ring., on the multimeter.
The center knob is the Function knob.
Set it to DC Voltage.
If just a symbol is shown, set it to the dotted line over a solid line symbol.
If there is more than one DC Voltage scale, set it to the 0 - 50 Volt scale.
The plug of the AC adapter (Charger) that plugs into the laptop, has a center hole, and an outside cylindrical metal shell.
The center hole is Positive.
The outer cylindrical metal shell is Negative.
Positive probe lead to the center hole, then touch the Negative probe leads to the cylindrical metal shell.
You should be reading 19 Volts, or VERY close to it.
Also have an assistant gently wiggle this cable, while you are testing.
Have them wiggle the power cable TO AC adapter, also.
An intermittent reading indicates a broken wire, or wires. Discard AC adapter, obtain a good one.
The port on the laptop that the AC adapter (Charger) plugs into, is the DC Power Jack.
AC adapter checks out it's on to the DC Power Jack.
Post in a Comment if you wish to go on with the diagnosis.
