HP ENVY x360 - m6-w102dx power button blinking but blank screen

[Edgar152]

i have a HP ENVY x360 - m6-w102dx. Last night it was working perfectly fine, i took it to work and left in my car for the day. when i got home the computer wouldn't turn on. i plugged it in thinking the battery was drained however after 30 minutes nothing happened. i can see the power cord light is on and when i try to press the power button for 15-30 seconds both the power button light and the power cord light will blink and will not turn on. i switch power cords and this didn't help either. 

Any other ways i can check the problem?

By the way, this model has an internal battery.

TIA

Hi

It is possible the Blinks are a clue...

EG: (Depending on the BIOS type and age)... A shortened version, is it anything like the table below?

BIOS Beep & LED error codes for Post April 2015 PC's

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.	LONG Beeps/Blinks	Error category
1	Single beep/blinks are NOT used
2	BIOS
3	Hardware
4	Thermal
5	Main-Board

Category	MAJOR/MINOR	Issue description	Troubleshooting Steps
BIOS	2.2	The main area (DXE) of BIOS has become corrupted and there is no recovery binary image available. Also happens when updating BIOS.	Typically no steps needed. 1. Allow the system to complete its updates and changes. 2. If updates are stalling, attempt Sure Start Recovery.
BIOS	2.3	The embedded controller policy requires the user to enter a key sequence.	1 Follow any prompts given. 2 If issue persists, attempt Sure Start recovery.
BIOS	2.4	The embedded controller is checking or recovering the boot block.	1 Allow the computer to attempt to recover the BIOS. 2 If after several minutes the issue persists, attempt Sure Start recovery.
Hardware	3.2	The embedded controller has timed out waiting for BIOS to return from memory initialization.	Indicates potential memory failure. 1 Reseat memory. 2 Correct memory configuration. 3 Test with known good memory. 4 Replace affected component.
Hardware	3.3	The embedded controller has timed out waiting for BIOS to return from graphics initialization.	Indicates potential graphics chip failure. For integrated configuration (I/C): 1 For I/C, confirm if graphics is on processor or Main-Board. 2 For I/C where graphics is on the CPU, swap known good processor. 3 For I/C, replace Main-Board and/or processor as appropriate. If the add-in card requires additional power, verify the cord is plugged in. For non-integrated configuration (N-I/C😞 1 Reseat card if able. 2 Test known good card if able. 3 Replace affected component.
Hardware	3.4	The Main-Board displays a power failure (crowbar).*	Indicates potential power system failure. 1 Reduce to minimum config (CPU, Main-Board, PSU, 1 DIMM of memory) and isolate failed component. 2 Reduce further if issue persists. 3 Test known good PSU. 4 Replace affected component. 5 If unable to confirm source, replace CPU, Main-Board, PSU.
Hardware	3.5	The processor is not detected.*	Indicates potential CPU failure. 1 If able, reseat CPU. 2 If able, test known good CPU. 3 Replace affected component. 4 Replace both CPU and Main-Board if unable to perform steps.
Hardware	3.6	The processor does not support an enabled feature.	CPU being asked to support feature it does not have. 1..Clear CMOS of unit and do not use the chosen setting. 2 If CPU is verified to support setting, replace CPU.
Thermal	4.2	A processor over temperature condition has been detected.*	CPU overheat is detected. 1 Verify fan(s) are working as expected. 2 Clean fans. 3 Reset CMOS. 4 Replace thermal grease. 5 Replace CPU.
Thermal	4.3	An ambient temperature over temperature condition has been detected.	Computer overall temperature is too high. 1 Verify fans are working. 2 Clean fans. 3 Reset CMOS. 4 Replace thermal sensor. 5 Replace Main-Board if issue persists.
Thermal	4.4	An MXM over temperature condition has been detected.	The MXM Graphics card has overheated. 1 Verify system fan(s) are working. 2 Clean fans. 3 Reset CMOS. 4 Replace MXM card.
Main-Board	5.2	The embedded controller cannot find valid firmware.	Controller is missing appropriate ROM. 1 Remove any recently inserted Hardware. 2 Reset CMOS. 3 Update BIOS while affected components are removed. 4 Test known good component. 5 Replace component or Main-Board as needed.
Main-Board	5.3	The embedded controller has timed 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.
Main-Board	5.4	The embedded controller has timed out waiting for BIOS to return from Main-Board initialization.	Main-Board isn’t initialising quickly enough for component. 1 Verify the correct power supply being used. 2 Reset CMOS. 3 Reseat components, 4 Test known good components. 5 Replace defective parts found.
