Must restore bios every start up

[RyWalk]

Hi, I noticed recently in my computer that my Nvidia graphics card wasn't "working" on my laptop, and after trying many fixes found an outdated bios to be the issue.  I upgraded the bios and it created some problems.

On the start up, I got a blue screen saying "not fully acpi compliant" and my computer wouldn't even start up.  My fix from looking around online was to turn on the computer while holding win+B, the computer beeped, and it started a bios recovery tool, and seemed to reflash itself.  After that the computer started fine, and the graphics card was working again. Yay!

But now every time I shut down, on start up it happens all over again.  The blue screen cutting off startup, I power off and back on with win+B, it reflashes, and everything is fine again.  So what's the real issue here? I shouldn't have to restore my bios every time I turn the computer on.

Are you using a BIOS posted on your model's support page?

Yes, that is the site I updated it from.  And it appears to be the current bios as well after the 4 different "recoveries" I've had when I turn on the computer.

I should add that I've also tried reinstalling the bios again all together with a new download and run a few days ago, just to have the same thing happen again once I shut down the computer.  During the reset when I was doing the second install I didn't get a blue screen though, so I thought it fixed the problem.

You could always try the previous version of BIOS:

I might give that a shot.

The most previous version is the one I upgraded from that wasn't supporting my Nvidia GPU.  I'll have to look into previous versions of my GPU driver as well.  I like the idea of having my drivers up to date though for better performance.  Is there a possibility of having a new bios update soon that may eliminate the problem with this one?

(or maybe it's a sign to get windows 😎

***Update***

I decided since last posting that waiting for a new bios upgrade was probably my best bet to see if it solved the problem or if it was a hardware issue.  Until then I was just living with never shutting down my computer to avoid the freezeups, because everything else was working brilliantly.

I just installed some regular windows updates, and when my computer had to restart it didn't freeze.  I checked it twice more after the installations to see if the problem was gone. After a restart and a shut down with successful start ups, it looks like my problem has disappeared.  The bios is running fine and supporting my Nvidia card.

I'll add a screen shot I took of the update history in case anyone else was having this problem, I'm assuming one of them fixed my problem, because I hit the blue screen again two days ago when my computer turned itself off for an update. Today the bios is loading fine.  I'll come back to this forum if the problem ever arises again just to re-update.

Appear to  be having an issue identical to the one described in this initial post.  Initial error occurred immediately after the installation of the latest Nvidia graphics driver update.  Blue screen stating "BIOS not fully ACPI compliant".  After reading through several forums online, this appears to be the only one discussing this exact issue on this exact laptop model.  I have also had success getting th OS to boot using the "win+B" BIOS recovery tool, but it is becoming an annoyance.  I have installed all current drivers and installed all updates currently available via Microsoft Update.  Below are screenshots of all applicable driver versions and windows updates.  Please let me know if there is a way to resolve this issue without doing a complete reinstallation of the system using HP recovery disks.

After my post thinking the problem disappeared, the problem came back again a few days later. I decided to wait it out until the next bios update, since downgrading to a previous version was not letting my Nvidia card work on every driver I tried.
I'm on the newest bios for our system, F.23. For a couple days the problem was gone and I thought the new bios fixed it. But it started happening again. I'm afraid that can only mean it's a hardware issue that I will need to get fixed. The problem is I can't go 2 weeks without my computer while I mail it to HP, I need it for school right now.

Thanks for the quick reply.  That does not sound promising.  I read a separate post which stated that HP phone support recommended a full reinstall using the HP recovery disks would resolve the issue.  HP Support will reportedly provide them at no cost for this particular issue.  I called and should be receiving them shortly.  I've backed up all my files in preparation for the re-installation.  Personnally, I tend to agree with your assessment.  I'm concerned that it's a hardware issue which will require it to be sent back to HP for repair.  Hopefully, we're wrong...... I'll repost after the wipe and let everyone know if it fixed the issue.
