    HP 8460p won't wake up after sleep, needs hard reset and restart

    Hey folks,
    Fresh install of Windows 7 Ultimate 64 on an Elitebook 8460p. This model has an i5 vPro 2520 with an AMD 6470M GPU. I put a 240GB SSD in there, and decided to do a fresh and clean OS install. After the full install, with all of the drivers and firmware of the HP support site as well as a BIOS update, I have a really annoying problem.

    Whenever the laptop goes to sleep, and I subsequently try to wake it up, it only partially wakes up. The power LED illuminates and the fan kicks on as if it were on. The wifi indicator LEDs also come on but only in orange, as does the mute button. The HDD access LED kicks on for a second when you first try and wake it, but then shuts off.

    This issue is really annoying, and I've researched a ton how to fix it, but to no avail. I've read that tons of HP laptops with AMD cards have this issue, but none of the solutions people had seem to apply to me. Many mention an issue with the switchable graphics and using older Intel drivers, but the 8460p doesn't have a switchable graphics option in the BIOS or in catalyst converter. Also, I can't seem to install ANY intel graphics drivers for this CPU or the HD 3000 so I'm assuming it's locked out by the AMD card.

    Any help?

    Thanks,
    Alex

    Ok, well, after updating the BIOS, which didn't fix it, I restored the BIOS defaults, which did. Computer now works fine. I wonder what setting that worked with my previous install doesn't work with my new one.

          change the battery bios .
          maybe it forgets how to wake up
          Just cook it! It's already broken.

            Guys, I really appreciate you chiming in, seriously, I do. But if you look at my second post, I fixed it. I reset the BIOS to default settings now everything is fine. It's weird that it worked with those settings on my previous install, but not with my new install. Whatever, it's working now. Thanks though!

              twas the bios update not reading CMOS the same way as before. the update should fix the bits in CMOS, but not always. like if you jump 4 versions it may not. that's what ive found anyway with the thousands of computers i've refurbed, BIOS update being a standard process of the refurb.
              Things I've fixed: anything from semis to crappy Chinese $2 radios, and now an IoT Dildo....

              Sometimes you need to break shit to fix it.... Thats why my lawnmower doesn't have a deadman switch or engine brake anymore

                I would agree, but the problem existed preBIOS update. I flashed the BIOS to try and fix the problem.

                  CMOS corruption is also common, though, i see it mainly with Dells dimension line and crappy gateways.

                    Never had the pleasure of coming across it. I will say this though, while most laptops and PCs are fine with a quick reinstall of windows, and maybe a few drivers off the manufacturer site, HPs are always the biggest pain to get running. They hate fresh installs. There is always a problem of some kind.
