Thanks to those who reply in advance.

My daughter brings me her laptop states she has not used it in three days. The screen is flashing on and off (blank). Naturally the warranty ran out two months ago

1. I did some diagnosis, figured battery is first issue. not charging. Charging port led is flashing Orange and white.
2. Removed and reseated the battery, ram, and hard drive plugged AC cord back in and turned it on same issue.
3. Removed battery plugged AC cord back in and turned it on charging port led is white and flashing on for 4 - 5 seconds. Hard Drive starts and stops at same intervals.
4. Screen has stop flashing now.

Thanks again for any help

Hi
First:- Turn off the computer, press and hold the PWR button for 4 seconds.

Then - Leave only keyboard and mouse connected, disconnect all externally connected
devices such as Docking Station, USB storage devices, displays, and printers.
Unplug the AC adapter from the computer.

Next - Press and Hold the Power button for 15 seconds to Hard Reset.
Rinse and Repeat; Re-Connect the AC adapter.

NOW begin checking/testing/proving the Hardware is fit for purpose.
Power on your PC, press ESC (repeatedly), then F2 at the prompt.
Choose System Tests (Fast Test does a 4 minute hardware check).

Thank you for your reply.

First:- Turn off the computer, press and hold the PWR button for 4 seconds.

Laptop does not power holding power button any amount of time. Powers off when unplugged.

I did however popped the battery back in and and the charging port LED flashes white three times repeatedly

Then - Leave only keyboard and mouse connected, disconnect all externally connected
devices such as Docking Station, USB storage devices, displays, and printers.
Unplug the AC adapter from the computer.

There is nothing whatsoever connected to the laptop. 

Next - Press and Hold the Power button for 15 seconds to Hard Reset.

Nothing, charging port LED flashes white three times repeatedly
Rinse and Repeat; Re-Connect the AC adapter.

Nothing, charging port LED flashes white (1 second) then orange (4 seconds) times repeatedly for five seconds. Fan is spinning the entire time. Hard drive spins when LED is on then stops with audible sound. Remove the battery and the conditions remain the same.

CAN NOT proceed from here. Removed battery and  AC cord to power off. Left battery out and plugged  the AC cord back in while tapping F2 nothing. The conditions remain the same the charging port LED flashes white for five seconds and the hard drive spins when LED is on then stops with audible sound.

Closing the lid/screen stops the LED flashing, fan and Hard drive, reopen the lid and The condition returns charging port LED flashes white three times repeatedly
