Solved!

Hp pavilion will not power on. Power button blinks but that’s it, no beeps, fan or anything.

HP Recommended
HP Pavilion 15-bc515na
Microsoft Windows 10 (64-bit)

Hi, I have a boot problem I was hoping I might get help with if anybody is available or able to help.

 

Firstly, let’s get the product and problem description out of the way.

 

Product: HP Pavilion 15-bc515na.

Primary storage (RAM) - 16 GB (2 x 8GB)

Secondary storage (Primary) - 256 GB M.2 NVME SSD.

Secondary storage (Secondary) - 500 GB HDD. (Possible problem device - Issue started after swap)

GPU: NVidia GeForce GTX 1050 - 3 GB DDR5.

 

Issue: Laptop will not boot. Screen doesn’t turn on. Fan doesn’t turn on. Nothing only the power button blinks. When plugged in, the charging indicator is lit.

 

Q1) What is wrong with it?

A1) The laptop will not boot.

 

Q2) Has this ever happened before? How old is the laptop.

A2) Never happened before and the laptop is just over 1 year old.

 

Q3) What symptoms does the laptop show? Are there any signs of life?

A3) When trying to power on the laptop, the power button blinks and that’s it. No sound, beeps or fans.

 

Q4) What hardware/software changes have been made since the issue arose?

A4) Swapped a hdd.

 

Q5) Did the laptop function correctly after the swap?

A5) Yes, it worked perfect after the swap.

 

Q6) How long after swapping the hdd did the issue arise?

A6) The next day.

 

Q7) Was the swap performed correctly.

A7) To the best of my knowledge.

 

Q8) How can you be so sure?

 

A8) The first thing I done is grounded myself with an anti-static wrist band that was connected to an unpainted part of the laptop. I removed the bottom of the laptop to disconnect the battery. When disconnected, I proceeded to perform the swap. I was grounded the entire time, using a plastic pry tool.  I wasn’t rough or forceful with anything and everything was replaced where it was suppose to. Last thing was reconnect the battery and reassemble (No installing OS or nothing).

 

Q9) And you're sure the laptop worked ok after?

A9) 100% sure I was using the laptop straight after the swap. Straight away when the last screw was in I was browsing YouTube.

 

Q10) What troubleshooting methods have been carried out?

Q10) Disassembled again, removed battery and held the power button for 1 minute to drain any excess static, connected the battery again and tried to reboot, but didn’t work.

 

Disassembled again, disconnected the battery and plugged in the power cable (to power the laptop directly, bypassing the battery). The same thing happened, the power button blinks but that’s it.


Other troubleshooting methods:

 

reseated the hdd that was swapped (removed and replaced ribbon cable).

 

reseated RAM.

 

reseated battery.

 

reseated M.2 SSD (Primary-secondary storage).

 

power reset (hold power button for 15 seconds).

 

And that’s it.

 

So, to summarise, the laptop will not boot. Even when bypassing the battery. Reseating all hardware that I can think of, and even after the hardware swap the laptop worked.

 

When the power cable is connected, with the battery connected, the power indicator indicates it’s charging (orange LED).

 

When the power cable is connected, with the battery disconnected, the power indicator indicates that it’s at full charge (white LED).

 

Everything I done (Reseat hardware, drain excess static, troubleshoot battery and power port) has not worked and results in the same result (no sign of life only the power button blinks).

 

If you can help please do. I appreciate anything that might help get my laptop back without buying a new one or a totally new motherboard (cause I’m afraid that’s it 😞 )

 

Thanks in advance and any additional information that is needed let me know.

Hi guys,

 

I’m replying to my own post to propose a solution if any of you are having the same issue.

 

After 10 days off, I got the laptop booting again. I was reading a lot of posts with people suggesting replacing the cmos battery, so I decided to try that and it worked.

 

I followed the manual to disassemble the laptop down to where I could replace the cmos. I replaced it an assembled the laptop. To my joy it booted into Windows with a “cmos checksum invalid” error.

 

That was about 50 boots ago and I haven’t had a problem yet. I’m not sure what happened but the laptop isn’t even that old, should a cmos battery not last about 4 or 5 years?

 

Regardless, I got it back and only cost me a cmos battery and replacement thermal paste. To get more clarity on the issue, I looked through the event viewer to see that last event before it shut off.

 

In Event Viewer, there was two critical events from the same source (DriverFrameworks-UserMode) with the first showing “A problem has occurred with one or more user-mode drivers and the hosting process has been terminated. This may temporarily interrupt your ability to access the devices”, with eventID 10110.

 

And the second error “The device HP Radio Manager Device is offline due to a driver crash. Windows will attempt to restart the device in the shared process 1 more time before moving the device in its own process. Contact the device manufacturer for information about this problem”, with eventID 10116.

 

These critical events occurred at the exact same time, down to the second (according to event viewer).

 

These critical events are followed by 11 error events, reading “The time service has detected that the system time needs to be changed by 838180 seconds. The time service will not change the system time by more than 5400 seconds”, with eventID 34. 


The 11 errors happen from 28:03 to 28:15. That’s twelve seconds for 11 errors.

 

In summary, I got the laptop back working by replacing the cmos battery. The only thing that would let a bit of life back into the laptop. 

The event Viewer shed some insight into the last bit of logging that went on before it collapsed, although it doesn’t shed light for me but maybe somebody a bit more technical.

 

With critical eventID’s 10110 and 10116 coming from the DriverFramework-UserMode source.

 

And error eventID’s 34 coming from the Time-Service source. No other critical or error events and they are the last before it went off.


I hope I helped somebody with the information, but if not, spread the word on your issue and the community will happily assist.

 

Thanks again to the HP community, customer base and volunteers, one of which may have replied and tried to help

@RoboCoder

 

I reviewed your post and I understand that the computer is not booting to Windows and there is no display.

 

Don’t worry, I assure you I will try my best to get this sorted.

 

Have you tried removing the HDD which you installed recently and booting?

 

I see that you have performed all the relevant troubleshooting steps and it looks like a hardware issue. I recommend you contact support and check the available service options for your computer.

 

Here is how you can get in touch with support.

 

1)Click on this link – www.hp.com/contacthp/

2)Select the product type.

3)Enter the serial number of your device or select let HP detect your product option.

4)Select the country from the drop-down.

5)You should see the HP phone support number or Chat option listed.

 

Let me know how it goes and you have a great day!

 

P.S: Welcome to the HP Support Community 😊

 

If you wish to show appreciation for my efforts, mark my post as Accept as Solution. Your feedback counts!

 

Cheers!

Hi, thanks for your reply and attempt to help. 

I have followed the link you specified but my warranty ran out so I was not allowed further. I have no other option only this community, as speaking to HP by phone is only for warranty holders (which is disgraceful, it’s not like I’m asking it for free, I’ll pay out the a** not a bother).

 

I have also tried to remove the hdd and boot, but still nothing.

 

I have removed my m.2 drive that my OS resides on, still nothing. Not even a boot options screen.

 

I then went one further and pulled out my ram, tried to boot up again and nothing.

 

The laptop doesn’t even post. No RAM checks, no drive checks, just a blinking power button and that’s it.

 

Anybody ever experienced anything like this before? No life signs at all only blinking power button light and power indicator.  It's awful weird and it only seems to be HP products that people can’t seem to get booting.

 

There must be something badly wrong if the laptop won’t even post. I’ll just have to bin it or sell for parts.

 

HP have definitely lost me as a customer. Also, It’s funny it happened a month after my HP warranty ran out, very strange.

 

 If anybody is reading this do yourself a favour and go Dell or something else, a company where you are appreciate and treated well, not forgot about once you part with your money.

 

Again, I appreciate your help and suggestions.
