HP Envy-3077nr: Why won't my laptop display, or charge.

Tue, 22 Jan 2019 15:02:28 -0700

Problem:

The computer will not post. It shows signs of booting such as fans spinning, and the optical drive audibly initializing.

Symptoms:

With the factory issued charger inserted, I get a white charge-light for about a second, then it turns orange. The power indicator is also lit, however the HDD light is not. If the charger is removed when the computer is “booted” (I.E. Fans spinning) the light flashes white every second.

Things I’ve Tried:

Different chargers, universal, and brand name. I get the same results.
Unplugging the battery and CMOS and holding the power button for 30 seconds.
Tried and external HDMI monitor.
Swapping RAM with test sticks
Booting without the HDD
Booting with the battery disconnected

Notes:

The battery was swapped in November because it was dead.

The heatsink was swapped in November because one of the fans stopped spinning.

Windows was reinstalled because of a drive issue

Conclusion:

If anyone has any insight, I’d love some assistance. The service manual should be linked on the device page if that helps anyone. Thank you!

Hi guys, thanks for read this post, I have an estrange case: I own a laptop HP ENVY 17 NOTEBOOK PC , today I have open and change the thermal paste of the CPU and GPU, I have clean with air all the internal computer. I have assemble and test playing Fallout ;) once I finish I get out the battery and clean with wet toals the keybord and turn on btn.

Once I finish I keep dry 2hr, once I finish I try to turn on and it make some estrange sounds, this sounds are from the spears and it doesn’t turn on.

I have open the laptop, check all. There no burning smell or any dark mark, I have double check all parts but all see good, i have found that once I press the turn on I get 1 second of move on the fan in the laptop, it can charge without any issue but I cant get it turn on.

Any ideas to fix this PC?
