myr1 Posted August 24, 2011 Share Posted August 24, 2011 Hi all, I've just extracted and patched DSDT for HP TC4400 (with bios version F.0C). Everything including tablet (via TabletMagic 2.0b18) seems to work (Broadcom Ethernet not tested yet, Intel wireless doesn't have a kext). Maybe it could be useful for someone. Enjoy EDIT: New version in the next post. dsdt.aml___OK.zip Link to comment Share on other sites More sharing options...
myr1 Posted August 27, 2011 Author Share Posted August 27, 2011 Here is a new version of DSDT. Changes in RTC, HPET, LPCB, TIMR and PIC. This means USB is working at its full speed (480 Mb/s), lower CPU temperatures, Bluetooth fixed. Still not working: Sleep (not tested), Wi-Fi (Intel) - missing kext. I forgot to mention that I am using bautzen's kexts and bootloader from bautzen's guide: http://www.kexts.com/downloads.php?do=file&id=1716 Enjoy dsdt.aml_7IRQFIXES_HPET_RTC_TIMR_PIC_.zip Link to comment Share on other sites More sharing options...
trektrek Posted February 11, 2012 Share Posted February 11, 2012 Hi, I appreciate I am a little late with the post, but.... Thanks for the dsdt - it is great that someone still loves these little tablets!! I was using the one from bautzen, but your one seems to detect the serial port correctly so I can use the pen and modem. I don't have any bluetooth though for some reason - I didn't with bautzen's either so I have no idea why since both advise that bluetooth works. I have a TC4400 with a T2500 CPU. Any ideas with the bluetooth problem? It is enabled in BIOS, and works correctly in Win7. Also, did you manage to get the internal SDHC card reader to work - bautzen didnt manage to get it to work and it wont show my card with this either I am fairly sure I had it working at one point in Leopard although I cannot be entirely sure cos it was a while ago. Anyway, any help with the bluetooth issue would be very much appreciated, Thanks very much again Link to comment Share on other sites More sharing options...
myr1 Posted March 20, 2012 Author Share Posted March 20, 2012 Try pressing the "wireless switch" (hardware button to turn on/off BT+WiFi) and restarting. I think it showed me the normal (not crossed) bluetooth icon. I didn't have any luck with installing the card reader kext. I've tried many, but none of them worked. (Probably just needs to have edited Info.plist inside the kext or the binary should be patched. It could also be completely incompatible with Mac OS X just like Intel wireless, which is unlikely.)

perez6991 Posted May 10, 2015 Share Posted May 10, 2015 Does anyone have the DSDT file? The links are dead unfortunately. Please and thank you. Link to comment Share on other sites More sharing options...
