Notebook HP Omen 17-w012ng trouble turning on

[FabioSoares]

Hello everyone. These events have been happening lately, so I am kinda frightened. My computer is a HP Omen 17, 3 years old, the battery doesn't charge to the full, although the windows sign shows the battery is 100% loaded. About a year ago I have noticed the battery lost its load capacity to 50-60%, which led me to use the laptop only on AC power since then. 

What happened that really scared me out was, when one day the computer just couldn't wake up (I usually set the computer to hibernate or sleep, so my work is well preserved in the memory). Instead the caps key was blinking several times, I thought at first that could be some kind of bug, didn't realize that was a code for the error detail. Unfortunately I don't remember exactly the pattern of the blinking leds, I just can remeber of three long ones. Fortunately I pressed the start button to force the laptop to turn off and turned on again, successfully booted to Windows and I could work normally. 

This happened about a week ago and I decided no longer set to sleep but just hibernate. It was working fine until yesterday night the computer just couldn't boot! The keyboard leds turned off suddenly and so was the computer itself. However the laptop kind of continued (trying) to turn on, after three times the HP screen appeared and the OS loaded normally. 

I have performed all tests of HP PC Hardware Diagnostics, however every single component I tests shows a successful result. Even the battery, which I think should be replaced, gave me a success result. Another possible souce of errror must be the AC power adapter, so I test it as well, with success result. To find out if it was really 100% perfect, I repeated the battery and power tests with the laptop put on battery. Again it passed successfully, however with the battery on 90% level, the computer turned off!

My biggest question is, besides energy and battery what is another possible cause of this issue, and how can I prevent it? I am aware that three years may be normal for these type of laptops to present problems, however I have owned computers that lasted much longer, whose problems took really much time to appear, and I don't remember this issue of turning off/on troubles. 

Anybody who could give an answer I do thank for the time and attention given. If more information needed, I can provide here, I just didn't now because it could be too much (and possibly not need) information.

Just to give an update. After I posted the last message, I tried to turn my computer on three times, of which all failed at first. Now the results have been something different:

Boot device not found

Hard Disk (3F0)

It only leads me to hit F2 to perform memory or hard drive tests, which I've done and the results were fine. After turning off by hand and trying to turn on a couple of times (two, three or four), the computer booted. This behavior happened while I tried to turn the on computer with the AC power and battery only, with keyboard lights on and off, with and without usb mouse, and waking up from hibernation and fresh start-up. The time between every time I tried to turn on the computer was about 4 hours to a day. 

I am still suspecting the bad battery is the cause, but I am afraid of performing the hard reset taking out the battery and hold power button for a minute. I don't exactly found an answer on what will that affect my computer after. I haven't tried booting only by AC Power either, I really don't know how safe would it be for computer hardware.

If anybody could give a hint of what is going on, and what is left to be done before giving up on this laptop, I'd be extremely thankful.

Cheers

Since there is no answer from anybody so far, I will add some more information here. 

In the last two weeks I have been facing this issue, sometimes my computer boots normally and it works for hours, but most of the time it doesn't, leading me to frustrating attempts to boot it into OS and getting stuck on that old known "Boot device error" screen.

After a lot of research in forums, sites and groups whatsoever, I have tried many of the suggestions given:

1. Reset Bios to default;
2. Hard reset of laptop, by removing the battery and pressing the power button for 15 seconds;
3. Enable Legacy Support (CSM) at Bios;
4. Perform the diagnostics of memory, short DST and long DST hard drive;
5. Change boot order;

None of those have worked. Actually what did work was time and persistence, I think, because now my HP laptop turns on after many times I turn it off and on over and over again. One strange thing I noted was that the SSD, on which my OS is installed, was not recognized at Bios, under UEFI boot order I see only OS Boot Manager, sometimes the "Windows Boot Manager" appears, most of the time it does not. This laptop has an SSD and a HDD, then I realized the tests peformed in the F2 diagnostics were on the HDD, it seems the SSD was not detected at all. That explains the message Boot Device Error, if the computer cannot "see" the SSD, then it won't boot. The SSD is a Samsung M.2 NVMe PCIe 256GB.

I even tried to boot from USB using a Windows 10 installation media, it worked, but I couldn't see the SSD drive, the C: drive then showed the files present at the 😧 drive. Today I was almost going to disassemble my laptop, in order to check the physical state of the SSD, I gave another try and the miracle happened. The computer is now almost 8 hours working without any error. I must mention that since I removed the battery, still believing the battery may be the source, I am using it only by AC power backed by a UPS. Next time I'll try turning it on without the battery and see what happens.

Based on all signs presented I don't think there is a severe problem with the mainboard or the SSD, but I guess it must be something related to the startup process, some component that fails to power on and thereby its dependent parts (which I suppose includes the SSD) became unavailable. My question is why does the notebook work fine after booted but can hardly pass the booting process? While I press the power button and the screen turns on, I hear a clicking noise as the computer turns off then after a few seconds turns on again and gets stuck on that boot device error again.

Maybe my case is too specific that there are no solutions found yet. In the while I'll keep my computer on and as soon as I figure out something that may be causing this behavior I'll post here for the community.

Hi @FabioSoares

Welcome to the HP Support Community. 

Appreciate you trying the steps. This looks like a hardware issue, I'd suggest you Contact HP in your region regarding the service options for your computer.

If you are having trouble navigating through the above options, it's most likely because the device is out of warranty. If yes? please send me a private message with the region you are contacting us from. Check next to your profile Name, you should see a little blue envelope, please click on it.

Thank you, Asmita, for your answer.

However if, as you said, local repair service is the only option, I am afraid to say I won't find any help from HP, since I cannot find a local service, provided that my country and region is not present in the list you sent me.

This means, I must continue to solve this issue by myself, or with the help of anybody who faced that and managed to solve. 

What really freaks me out is the fact the notebook is now working almost an entire week with no overheat, no blue screens, no problem whatsoever, all tests from the HP Diagnostics don't show any problem at all. The main trouble is to turn the computer on. Until I'll have enough money to afford a new computer, the only option I have is to carry on with the problem investigation independently.
