    Hello,

    Yesterday I installed the Windows 7 Professional RTM from MSDNAA on my Compal JHL90, before I installed the RTM I used the RC since it came out. With the RC I had single problems, so I expected to have no problems with the RTM aswell. Unfortunately I do have a problem.

    I have the laptop on the AC most of the time (with the battery plugged in the notebook), but suddenly (after about 3-4 hours) I saw the brightness going down so I looked at the powerplan...I saw that it was running on the battery (while the AC adapter was on). After 5 seconds it started to run on the AC again. Today I had the same problem again, so I decided to let the battery run out and hopefully that solves the problem...but it didn't :(

    While the battery still had 59% remaining, it did go into hibernation mode because Windows 7 thought the battery had reached it critical level. After I restarted the notebook, it showed to me that it had still 58% remaininng...so no reason to think such a thing.

    I looked futher and I saw a questionmark in the device manager, it says "Unknown Device". I clicked it and saw it had to do with the ACPI-Compliant driver from Microsoft. If I click on details it says this to me: "ACPI\CPL0002"" , so the problem is the ACPI driver.

    I installed the latest Intel Chipset drivers, but it didn't help :( Somebody who might know how to fix this? Because it is very annoying ;)
