No Automatic Laptop Dimming After Externel Power Source Removal #12

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Unplug the external power once .
2. The display does not dim.

What is the expected output? What do you see instead?

Earlier,whenever I removed the ac power,the screen did dim slightly on its 
own,now the 
brightness remains the same.

What version of the kext are you using? On what kernel and processor?

OS Version:10.5.5(build 9f33,vanilla kernel and kexts with efi on GPT table)
I am Chun Nan smart battery manager.
I got 10.5.5 by using iATKOSv2 and 10.5.3,10.5.4 and 10.5.5 update using Netkas 
Method.
and use Titan for Graphics.

Processor is Intel Core Duo T2050@1.6GHz.
hp laptop dv6114tx
Please provide any additional information below.

Please turn on DebugMessages in the Info.plist, reload the kext and try to 
reproduce the 
problem. Attach output of this command:  -NA-

My bus freq was wrongly reported(System Profiler) even before using this kext.I 
use 533Mhz 
DDR2 RAM on HP Laptop (dv6114tx)
I guess this is because of SMBIOS(27,the one that came with iATKOS v2)
your kext says FSB IS 133MHz.

Do you think  using vanilla SMBIOS with Chun Nan SMBIOSEfi will solve the wrong 
Bus problem ?

Display dimming has nothing to do with speedstep. It is probably because you 
increased the brightness on 
battery and the laptop 'remembered' that (happens with mine). Try taking the 
adapter out, wait a minute, 
decrease the brightness manually using keyboard shortcut, then plug power back 
in.

FSB speed is correct. 533 MHz is the quadpump value (marketing strategy :P). 
133 * 4 = 532 mhz for the 
memory. 133 is the actual fsb.

Marking as Invalid as there are no bugs.
