No signs of any function

[pcman111]

I have had this laptop for a while. One time I took out the battery and put it back in. When I put it back in it didn’t work. If I plug it up there a no lights except for a white blink on the left of the Ethernet port. I also tried a hard reset: no difference. Please help!

@pcman111, Welcome to the HP Support Community!  

Thanks for reaching out about your query regarding your your laptop having no sign of life! 

We're thrilled to have the opportunity to assist you and provide a solution.  

Let's go step by step and try to get your Envy M7-n109dx back up and running.

Things to Try:

Power Reset Again (Just in Case)
Since you've already attempted a hard reset, let’s try it again but with a slight variation:

Unplug the charger and remove the battery.

Hold the power button down for at least 30 seconds to drain any residual power.

Leave the battery out and connect only the charger.

Try turning it on and see if anything changes.

Check the Charger and Power Port

Ensure your charger is working by testing it with another HP laptop if possible.

Inspect the power port on your laptop for any dust, bent pins, or damage.

Try a Different Power Source

Plug the charger into a different wall outlet or try a direct wall connection instead of a power strip.

Battery and Motherboard Check

If the laptop turns on without the battery when plugged in, the battery might be faulty.

If you still get nothing, the blinking light near the Ethernet port could indicate a motherboard or power delivery issue.  

Let me know if this helps!

Take care, and have an amazing day!
