Laptop won't boot up, power light and charging light flash

Hello, first question here.

I recently acquired a HP notebook, model number 15S-FQ2038NA. The previous owner had removed the factory ram and supplied no charger, so I fitted a new stick of compatible ram and acquired a replacement charger.

After letting it charge for about an hour, I tried firing the system up on mains power. The power indicator light on the right hand side flashes white and stays so for about three seconds, before turning off for another three. When plugged into the mains, the charging indicator light on the left hand side flashes white for a moment, then orange, then switches off over a period of about six seconds. There are no flashing lights on the keyboard.

Having followed a few tutorials, I have tried a number of power reset options, both based on those on HP's website for similar models and various YouTube videos. I also removed the battery, and even without the battery and plugged into mains power, the system does not power on and displays similar lights, which would suggest to me that the battery is fine and isn't the issue.

Does anybody happen to have any suggestions as to what to try next?

EDIT: Following numerous questions about the lights visible, I decided to capture some footage of them and add them here as GIFs since it's easier to show than it is to explain.


Charging indicator light (only when power via AC is connected)


Power indicator light (does not stop repeating this pattern unless internal battery is removed)

@tomeicowboy we need more info on this. Skip the seconds in between the repeats. How many times does it blink? If I understand you correctly. when connect to battery only, then "the power indicator light on the right hand side flashes white", but when you connect the power adapter "the charging indicator light on the left hand side flashes white for a moment, then orange" So, not the power indicator but just the charging indicator flashes. Correct? How many times?

@oldturkey03 Indeed, when on the battery only, the right hand side indicator flashes. When using mains power, the power indicator and charging indicator flash with the different patterns described - the lights last about three seconds, excluding the pauses. It seems to blink indefinitely - I last powered it on an hour ago and it is still flashing.

@tomeicowboy good. That is partly what we need to know. Now, don't count the seconds but count how many times it blinks during those seconds. How many times does each light blink until the pause? HP uses a two light blink code. Each light will most likely be a different number of blinks. Those are the numbers we need to know.

The power indicator light blinks once during a three second cycle - it is literally solid for three seconds, then off for three. The charging indicator light is solid white once, then orange once, then off for a moment. I am happy to record the patterns later on.

the charging light turns to amber because it tries to charge the battery. If it stays white, the battery is fully charged. So that looks somewhat normal. The power LED issue appears to be a motherboard generated error. We'll need to know what exact model your motherboard is.

If it is a corrupt BIOS read these steps carefully

HP Laptop BIOS Recovery Win and B or V Key

  • Check Key Combination: First, make sure you are pressing the correct key combination. On some HP laptops, the key combination for BIOS recovery might be different. It's usually "Windows + B" or "Windows + V," but it could vary. Check your laptop's manual or HP's official support documentation for the correct key combination.
  • Power Cycle: Turn off your laptop completely and unplug it from any power source. Then, press and hold the key combination ("Windows + B" or "Windows + V") and while holding it down, press the power button. Keep holding the key combination until the laptop's screen lights up or you see any signs of BIOS recovery.
  • Use a USB Drive: If the key combination method isn't working, you might need to use a USB drive with a specific BIOS recovery file. Visit HP's official support website, enter your laptop's model number, and look for the BIOS recovery files and instructions for your specific model.

Here is a good video on how to etc.

The video suggests that there should be lights on the keyboard that light up to indicate this, but no lights appear on the keyboard of my laptop - it's the power indicator light on the right and charging indicator light on the left that show any signs. On top of that, none of the light patterns correspond with any examples featured on the HP website.

Hi @tomeicowboy

Curious with the lights. As you probably know troubleshooting is a process of elimination. Also, when key press sequences are required I find repeating later is a good idea as I may not have followed a particular key stroke/timing sequence correctly. Have you tried the "Windows + B" or "Windows + V"? Apparently it can take a bit of time before there is a response.

Just an idea - have you tried plugging in an external keyboard to see if that makes any difference?

The other thing is removing as many components as possible to see if they are the cause of the laptop not turning on properly. If it does then just re-add one at a time until the faulty one reveals itself.

Good luck. Keep us posted.

Hi @aactech, thanks for your suggestions.

I've given them a go, and nothing appears to be kicking the machine into life. Since you're curious about the lights, as was @oldturkey03, I have edited the original question to include some video footage of them. As noted, there are no lights on the keyboard, and the only signs of life from the machine are the two lights featured in the videos.

Hope that might help!

@tomeicowboy

You stated that you fitted a "....new stick of compatible ram.....".

Did you only install the one ram module?

If so the best that I can find is that for this laptop series a matched pair of modules is required i.e. 2 x 4GB, 2 x 8GB or 2 x 16GB (max).

Perhaps give that a try and see if it works.

Ordered another stick, I'll give you an update when it arrives.

Hi Jayeff, gave it a go. Ordered an identical stick of Crucial 3200MHz 16GB DDR4 ram, it unfortunately did not solve the issue. Thank you for the suggestion, though!

Hi, I had this exact same issue, and I managed to get it working after leaving the battery out for about an hour, to give it time for any electricity to dissipate. I then plugged the battery back in and turned it on whilst holding windows key + b, i was then able to run through the setup and repair the bios.

Hope this helps.

I was using the the bios repair from a usb stick rather than the system repair.

Hi there frd, I gave it a go a few times based on your comment and HP's video on how to access the BIOS setup, and still no response bar the flashing lights detailed in the question. Thank you for taking the time to suggest an answer, though!

Hi Tomei_Cowboy, I forgot to mention that whilst the main battery was plugged out, i also unplugged the bios battery at the same time. This was the little connector by the wifi card. With the main and bios batteries removed, I held the power button in few times (for around 60 seconds each time) during that time for good measure to make sure any electricity had gone. After letting it sit for about an hour again, with everything still plugged out, you could then try just running it on the power cable only (no main battery or bios battery plugged in), holding windows + b (or v) first, then pressing the power button and keeping windows + b (or v) pressed until the screen came on. I didn't plug the bios battery back in until after the bios repair/update had completed. Other than that, i'm not sure as that's what helped solved my issue.
