    How it's possible to make RAID5 on L502x? Are there enough connectors? :D

    maybe using the optical drive caddy, like I do :D

    however I have some important data and configurations in both disks, so I cant test that by myself, I will relase the v6 version in some time, if someone want to try, he will be welcome.

    I will also relase a new modded version for the L702X wich had two native hdd connections or 3 if also they do the optical drive trick , esata also may be an option, but since it is an external option, I dont think it will be a nice idea.

    oh, here are more options unlocked wich will be avalible on the next mod

    battery charge mode, I dont know why it was on xpress by default.

    however, setting this option to standard, may fix some GPU power crashes maybe?

    next version also will allow set service tag

    I know we have 3 connectors in L502x - normal, caddy and eSATA. So how can we use RAID10 which NEEDS 4 disks? Connecting 2 disks to eSATA? Is it even possible?

    Standard charge mode maybe would improve battery live (not time on one charging, but how quickly this time decreases)

    nope, you are right.

    the l502x isnt designed for raid ^^

    thats why I was asking that would be a little more usefull for L702X users.


    more updates.

    I unlocked the AMT menu, however, while entering on it, it get a black screen, and then it seems to boot the normal system after a while, not sure if missing modules or hardware is the cause of that.

    the other update is way more interesting.

    I unlocked the computrace setting, this means, it does not matter if you already set it before, It will not be grey anymore and you can enable or disable when you want.

    however, to keep this setting optimal, is recomended to use a bios setup password to prevent unwanted changes of this setting if someone got unautorized access to your laptop.

    So, according to IFR suppress thingy:
    Code:
    0x314B6 				Setting: UEFI Boot, Variable: 0x3 {05 A6 89 00 8A 00 31 00 02 00 03 00 00 10 00 01 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00}
    0x314DC 					Default: 8 Bit, Value: 0x0 {5B 0D 00 00 00 00 00 00 00 00 00 00 00}
    0x314E9 					Default: 8 Bit, Value: 0x0 {5B 0D 01 00 00 00 00 00 00 00 00 00 00}
    0x314F6 					Option: Disabled, Value: 0x0 {09 0E 5E 00 00 00 00 00 00 00 00 00 00 00}
    0x31504 					Option: Enabled, Value: 0x1 {09 0E 5F 00 00 00 01 00 00 00 00 00 00 00}
    
    So enabled by default values should be 09 0E 5F 00 00 00 01 00 00 00 00 00 00 00?

    And thus the discussion splits :D Looking at for instance High Resolution Graphics, which is enabled by default, you should change:

    5B 0D 00 00 00 (00) 00 00 00 00 00 00 00 to 5B 0D 00 00 00 (01) 00 00 00 00 00 00 00, and
    5B 0D 01 00 00 (00) 00 00 00 00 00 00 00 to 5B 0D 01 00 00 (01) 00 00 00 00 00 00 00

    It just decodes the formset based on known opcodes, the form doesn't store any values, the values are stored elsewhere (nvram setup variable?)
    Code:
    Setting: UEFI Boot, Variable: 0x3 {05 A6 89 00 8A 00 3A 00 02 00 03 00 00 10 00 01 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00}
        Default: 8 Bit, Value: 0x0 {5B 0D 00 00 00 00 00 00 00 00 00 00 00}
        Default: 8 Bit, Value: 0x0 {5B 0D 01 00 00 00 00 00 00 00 00 00 00}
        Option: Disabled, Value: 0x0 {09 0E 5E 00 00 00 00 00 00 00 00 00 00 00}
        Option: Enabled, Value: 0x1 {09 0E 5F 00 00 00 01 00 00 00 00 00 00 00}
    End of Options {29 02}
    
    Actual binary file:
    Code:
    05 A6 8B 00 8C 00 3B 00 02 00 02 00 00 10 00 01 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 
    5B 0D 00 00 00 01 00 00 00 00 00 00 00 
    5B 0D 01 00 00 01 00 00 00 00 00 00 00 
    09 0E 5E 00 00 00 00 00 00 00 00 00 00 00 
    09 0E 5F 00 00 00 01 00 00 00 00 00 00 00

    I wonder though if thermal configuration can be not only shown, but actually made to work .. because this fan behavior is driving me insane. At least I was able to come up with some form of fan control for it, but I'd prefer an option to define the threshold in BIOS over anything. By the way, no luck with setting UEFI option as enabled by default.. because it seems like bios defaults are bing restored from nvram variable as soon as you boot the capsule in crisis mode.
    What I'm trying to achieve is to get rid of CD/DVD for recovery, instead I'd like to use PFlash cause it's more safe, fast and SILENT .. but UEFI mode needs to be enabled for that.. no dice.

    Hi, I think my laptop might be completely boned now. LoL crashed on 450mhz underclock, and then on 430underclock. played 9 games today but just now it decided enough is enough. Not sure modded bios, lowest recommended one for my laptop though. feeling pretty sad.

    using MSI the maximum temperature was like 58 and the clock speed was reset so I know the card crashed.
