HP Envy 20 Touchsmart won’t start up

Envy 20 Touchsmart

Computer won’t start up. Power/outlet is not the issue.  There is a little light on where the adapter plugs into the computer, and the power light on top of computer comes on, but I never hear a fan or any type of start up noise and the screen remains totally black. I have tried (multiple times) disconnecting power and holding power button for up to 15 + seconds, and also have been through several tries of resetting bios via troubleshooting instructions found online pressing a sequence of F10 and F5, and F10 as instructed.  I would appreciate any tips or direction as to what to do next.

 

Computer has Windows 10 if I recall.

 

thank you.

The power adapter might be the problem, if it is supplying just-enough power to turn on that little light.

Take a Multimeter, and test both the voltage and the amperage being produced by the adapter, and match the actual numbers to the numbers printed on the label of the adapter.

 

If your ON/OFF button is not working, then your computer will not start.

If it is working, and the motherboard has failed, then "no fan noise" and "no images" are the usual symptoms of such a failure.

 

I don't know why people "jump" to try to update/recover the BIOS -- personally, I never try that technique -- it is extremely-rare that changing the BIOS will resolve my problem.

 

Can you physically remove the disk-drive, and connect it as a "secondary" disk-drive in some other computer, to see if you can read the files/folders that are stored on the disk-drive?  Probably, the disk-drive will be fine.  The "no fan noise" symptom is the most-important "clue" that the motherboard, not the disk-drive, is the problem.

 

Is the original HP Warranty still active?

If so, contact HP, to open a claim against the warranty.  HP will repair/replace your computer.

But, if the warranty has expired, then it is your choice whether to pay HP to trouble-shoot & repair, or to pay a local computer technician to trouble-shoot & give you options (it's expensive to replace a motherboard).
