First make sure that computer is getting power, check that AC adapter is connected and led light is on.
Second, remove the battery from laptop and all the cables. Press power button down for 10s. But the battery back on, connect AC adapter and try to start. If still nothing, possible HW issue.

SOURCE: C500 Laptop won't come on power button just flashes

Have you tried attaching an external monitor when the LCD screen is disconnected from the motherboard? this connector is located under the keyboard strip – a piece of plastic just above the keyboard.
If it works, this way, then the video cable isn’t seated properly in the connector on the back of the screen. Plugging the video cable back in should fix the problem.
I don’t know how comfortable you are with taking apart laptops but I think that this information could be useful for you.

Typically that flashing light means low battery. Which makes sense, as you probably have an issue with the AC Adapter that you plug into the computer to charge it, or the DC Jack that this adapter plugs into on the laptop. Either of these things will cause your computer to not charge the battery, and if there isn't enough power it won't turn on.

  1. Press the Power button on the Wii console to turn it on.
  2. Remove the battery cover on the back of the Wii Remote you wish to sync up, and press the SYNC button just below the batteries. The Player LED will blink.
  3. Open the SD Card Slot cover on the front of the Wii console and press the SYNC button on the inside of the compartment.
  4. When the Player LED blinking stops, the syncing is complete. The LED that is illuminated indicates the player number (1 to 4).

No power. All power cords checked and tight. With


Check power adapter’s DC plug that connects into the laptop power socket with a multi-meter, the voltage should be slightly higher than the voltage that is printed on the label on the bottom of the adapter. If the voltage is zero or way below the voltage that is printed on the label then the power adapter is faulty and needs to be replaced.
If the adapter is OK then connect it to the laptop and power it up, then look at the power/battery charging LED light and wriggle the power plug in the laptop's power socket. If the power/battery LED light flashes and in a certain position this LED light stays firm, then the power socket is either faulty or it has a dry solder joint where it is connected to the motherboard.
This can be repaired but it requires the laptop to be completely dismantled to get at this power socket and repair. If you cannot DIY then I suggest you get a quote first.

Touch pad always lit up...


Yes, if the leds are all lit and no respnse, then your board in the top counsel is faulty. Have you haad any power surges recenlty.? Power surges sometimes mess up computer boards. But yeah, it sounds like its bad tho. There should be led light on unless you start pushing buttons. Have you hit the "off" selection. If nothing turns off the led lighting, it sounds like the board might be bad...hopefully this helps
