HP Stream 11 Laptop wont turn on- has flashing lights

[sydneypasse]

I've had this computer for about 2 months now, and I use it mainly for school. This morning I noticed there was a black, almost grainy looking, screen covering a part of the toolbar/hotbar. If you pushed on the back of the computer screen it would get bigger, but then after a while it would get smaller. I'm not sure what it was or what I did for that to happen. I decided to hold the power button down to reset it to see if that would help. Once it shut off I pushed the power button again but the screen stayed black, and then the caps lock light started to flash. The light did five long and three short flashes, then started the cycle again. How do I fix this?

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.

AND/OR - Power on your PC, press Esc (repeatedly), then F2 at the prompt.
Choose System Tests (Fast Test does a 4 minute hardware check).

AND/OR - Windows Logo key + Ctrl + Shift + B
(This key sequence actually restarts you graphics drive(W10 only).)

AND/OR - If you’re using multiple displays, try projecting video to a different monitor.
Press the Windows Logo key + P, select a display, and then press Enter.

You get a LONG (MAJOR) signal category, RED LED &

then a SHORT (MINOR) signal category, WHITE LED.

Major – the category of the error; Minor – specific error in that category

The AUDIBLE repeats 5 times, and the VISUAL until power is removed.

Main- (Mother) Board

5.3

The embedded controller times out waiting for the BIOS. Component is not reachable by BIOS in certain time limit.

1 Reseat component. 2 Test known good component. 3 Replace component or Main-Board as needed.

I tried all of it (exept the last one- I don't have another monitor) but the computer still wont turn on. After I press the power button for 15 seconds the lights stop, but then when I try to turn the laptop back on the lights start up again.

Hi

The 5-3 combination indicate a Main (Mother) Board failure, which is terminal.

My last roll of the dice suggest this article.....
