Hello, recently I have updated my bios on the EliteBook 8570w and after the restart it booted fine and I went on with my work. I left it overnight to download a big game and in the morning when it downloaded I started the installation. I wasn't home for a few hours, but when I came back the laptop was very glitchy for some reason, so I ended up force shut downing it, and starting it back up. But for some reason, it didn't boot and all it gave me was a quick power button flash. I read on a forum that could indicate a CPU problem. So I tested it with a working spare and the same result. I tried doing the bios recovery but my power button cable broke and I couldn't enter even make a recovery USB because the bios program simply wouldn't launch on a different computer. I am on a dead-end and every forum I looked at said nothing about the one quick power button flash. Any help would be appreciated.
