But I do not believe the BIOS update provided by HP actually caused the tablet to brick, more along the lines of user impatience. I have 5 IT certs/degrees and worked in tech support for a large computer company and learned that many users are simply impatient. I updated the BIOS on both of the tablets I bought and both when fine. However the update took about 10 minutes maybe more. Once you tap the exe file from within Windows it will take a few minutes to extract and then then tablet will reboot, but it boots to a black screen with tiny wording and it appears to stick, and that appear to stick last about 8-9 minutes and in my experience many inexperienced users think something went wrong and hold the power button down attempting to restart and it bricks. So my advice.
1) If you have never updated a BIOS and you do not want to read the instructions then you may want to ask a tech friend to help or advise you.
2) read the directions on how to update the BIOS, it does mention that there may be a delay and not to force restart the tablet.
3) If you do opt to update the BIOS, start the process and walk away, go eat, or watch an hour TV show, but allow the tablet to do it job.
The worst think I have seen when an inexperienced person updates firmware on a device and they will sit and hold it and in doing that they get frustrated that it appears to be taking too long.
So if you update that BIOS please allow sufficient time for the system to complete it job. And if you do press and hold the power button to do a forced restart please post or tell the tech.
