    Hey Seketh, did you manage to install new leshcat drivers (13.4 v2, 13.5beta2) with working brightness on both GPU ??
    I saw in comments on leshcatlabs.net that lesh give you new value to test, did you give it a try.

    Well, I made that comment prematurely. The switching stopped working after reboot, and the value did nothing. So, still no proper drivers for the Tm2, which is a shame, since both the 13.4/v2 and 13.b2 fixed my crashes with the Intel GPU.

    I would recomend everyone to post a comment in the leshcat website. We'll only have a proper driver if he feels the need to fix a specific laptop config. I'll keep testing new releases and post the results here.

    Meanwhile, I've rolled back to the OEM HP drivers, since I need brightness in the AMD GPU. By the way, does anyone knows of a more recent AMD package with working brightness?

    I'm still using 12.9 Sep4 UnifL, brightness working on both GPU but sleep mode not working on them and performance is poor especially on AMD card.

    Anyway I form a ticket a while back and problem is still there :-(

    EDIT: Hey Seketh I read somewhare on the net that there is Advanced Menu in TM2's BIOS where you can turn off Intel GPU, have you try this ? ?

    Try spamming the "A" key on the keyboard while trying to get into the BIOS, this should get you into the BIOS with all advanced settings available.

    If you dig around a bit there is an option to use "Hybrid" graphics, "iGPU" (intel only) or "dGPU" (AMD only).

    I haven't personally tried messing with it, I'd be curious to see how it impacts drivers and power consumption. Would be handy if "dGPU" mode allowed us to use normal AMD drivers.

    Wow, that worked!

    There's a lot of options, including Fan Control temperatures and something called CPU Boost. I have no ideia what most of that stuff does though.

    Would feel more confortable messing around the bios if I knew how to reset (clear CMOS) if anything went wrong. Anyone has any ideia on how to do that?

    You want to leave that enabled if your CPU supports turbo modes.

    On newer processors, intel has begun giving their chips two speed ratings: the normal maximum clockspeed, and a "turbo" clockspeed that can be used as long as temperatures stay low enough.

    So, for example, I have a TM2-2151nr which comes with a Core i5 U470. Intel markets this as a 1.33 GHz dual core, but it will run as fast as 1.86 GHz when in "Turbo" mode.

    Your signature says you have a TM2-2050ep, which comes with a Core i3 330UM. Core i3 processors do not support Turbo mode, so that particular feature isn't going to work for you.

    I figured as much.

    I tried searching the web for more details on the various advanced settings, but couldn't really find anything besides disabling power saving features, which I'm not really interested in. There's intereresting stuff like ACPI 3.0 T-States, which is disabled by default and I suppose it's related to power features, but couldn't find any info about it, could possibly improve battery life or even performance.

    But what I was really interested in is having the fan starting at a much higher temp, but the thermal controls make no sense (for me). My fan kicks in at about ~38º, which is very low, but on the bios there only seem to be 2 stages of fan speed, low and high, at 55º and 70º respectively, when the Tm2 has 3 stages of fan speed....

    I haven't tried enabling only the dGPU (AMD), but from what I've read in a forum somewhere, it seems the architecture requires the iGPU (Intel) to be always active. So, it seems you could disable the dGPU and probably install official Intel drivers, which is useful for some people, but not disable the iGPU.

    Still, as I said, I haven't tried it. I read that you can boot with only the dGPU active, but drivers won't load. If anyone wants to try... I can't risk a black screen right now, I need the Tm2 for college stuff. :p

    There's new driver on leshcat page but after reading comments it seems that brightness still not working. :-(

    EDIT: Hey Seketh or anyone that tested new lesh drivers could you post some info.

    I use Leshcat 12.8 in Win8
    It is the only that allows to go to sleep and has working brightness.
    The only issue is that it doesn't wake up from hibernation on AMD card because of Intel Driver issue

    Yahoo! I've done this!
    AMD 9.11.11 driver, Video Hardware Acceleration works, switching works almost instantly, very good!
