Trying to downgrade the latest HP Bios
Hi. So i've been to the HP support forum and they are nice but so far haven't really been all that helpful. I'm still stuck.
The issue is I recently updated to the latest bios for my HP -15 laptop, F38 by insyde, and since I've done that the machine has gotten progressively slower and is running hotter - fan is on a lot. I'm not 100% sure it is the new bios but I've done a lot of other things - repair installs, going back to win 8.1 and back up to win 10 etc lots of fun and I'd like to give a downgrade of the bios a try to eliminate that as possible cause.
So on the hp site they have you download the bios file for your model laptop. You then double click it and it has an installer thing in it. It offers this:
Since it is an older bios, one that I know works well for me, F25, it won't let you update it through windows which is the first choice. So I tried the next choice and you basically install the bios files to a usb flash drive. The next step is to turn off computer, put the flash drive in, press windows key + B and hold power for 3 seconds. Release the power and hold windows key and B until a bios utility comes on the screen. Another version of instructions has you release win key and B along with power at 3 seconds. No matter what I do though, nothing happens, no bios screen and no update of bios. Reading on the forum, this seems to be a common experience with people who have tried it. It's like it doesn't work. I tried different usb ports, usb drives... no difference.
Another option is to rollback the bios by pressing some keys. This doesn't work either though since it doesn't have the previous bios and only offers to reinstall F38. So I can't roll back.
If I press esc as the computer boots, there are a few options.. including system diagnostics and in there a firmware setting option. It looks like it offers a choice where you can point it to a bios to install but I don't know how to do that or if are any other ways to get the bios on.
I've tried also to put the most recent bios before F38 -f37, and same story. It's like it doesn't want you to do it and is blocking efforts. I know its an important update, it has the Spectre fix, but surely it there are problems there has to be some way to downgrade back down to an earlier bios?
