HP Envy 23 touchsmart won't boot

[Inf-Napoli]

Hi to all,

this year I've repaired in total 5 HP ENVY 23 TouchSmart, different versions but 4 of there with same problem:

- Black screen;

- no previous problems;

- fan working;

- white power led on;

Only one of these units  affect some heavy problem with external MXM video board (solved with a BGA reballing) but I full solved 4 of these with a re-programming of BIOS chip.

So, I'm sure that the black screen on these ENVY are caused in most of cases by BIOS CORRUPTION (or eeprom chip failure).

It's not possible to update BIOS with USB and recovery procedure: You have to change eeprom chip with new one or simply reprogram actual chip.

For this work it's necessary: patience, an air solder station, solder capability, some flux (or solde paste), full version of bios file for ENVY 23 TouchSmart, PIC/IC/EEPROM programmer and (optionally) a new eeprom bios chip.

In this article one of my work:

http://www.informaticanapoli.it/hp-envy-23-touchsmart-non-si-accende/

The article is in Italian and I know that this work is regarding to professional equipment and experience; but on the web I didn't found any info related to these AllInOne and BIOS issues and I think that some info are useful.

sorry for bad english.

Regards,

Carlo

They program the bios to disable the computer after warranty to increase sales....
Most computers now last just over 12 months to 2 years.
Mine has the same problem just out of warranty. So the Bios has self destructed hey.......

After the latest Windows 10 update the computer only turns on but does not boot up!

Thanks for showing your interest in the HP Forums,
I’d like to help 🙂

As I understand the computer isn't booting into windows after the recent windows 10 installed on the PC,

I need a few details to provide an accurate solution:

Was the update process interrupted?

When was the last time it worked (date) ?

Have you attempted any steps of your own to solve the issue?

In the meantime, please attempt the below steps:

Perform a hard reset

Attempt a BIOS recovery

If there's no display, use an alternate monitor

Run the System Diagnostics tests

I'm having the same issue. Any help with this problem please? I've owned it for about 3 years and now it's not booting at all. Is this under warranty?

"Connect an external monitor"? 

Where to? There's no monitor socket on this All-In-One...
