I have bought IdeaPad U310 i7 edition and it came with Windows 7 home edition (in fakeRAID and iRST) but i wanted to install Fedora 17 (next time CentOS 6.3 probably) (and virtualized Win7/8 on it)
1. So I turned windows off properly (no sleep, no hibernate), changed the sata controller to AHCI and turn off the iRST. (so there won't be any problem with access to BIOS next time)
2. I used external dvd to install fedora 17, during instalation, I realized, that U310 is not a BIOS computer, but newer EFI (or support UEFI booting). The main diference (for the OS) was in hdd tables ( BIOS pcs uses old MBR table format and EFI uses GTP format). The preinstalled windows mas in old BIOS mode with MBR disk tables, so for installing Fedora 17 I needed to rebuild these tables to GTP (I did so with gdisk command during instalation). Whan this was done, I installed root, swap and home to ssd and hdd used just for data. Everything went better than expacted, all system was booted in arround 20 seconds, just awesome, but porbelms:
Wifi: i have intel 2230 bgn adapter, and it is not supported.. (can by solved by finding and installing linux driver probably..)
Noise(cpu fan): (when on windows, there were no problem, on battery just pasive cooling, on AC active but continual) with new linux install, cpu fan come up very supprisingly with high pitch and it's not continual. When on battery the thing is same.
Power button: It keeps blinking whether computer is on or sleeps or on AC... It's really annoyng...
What should I do? Has anyone problems like mine are?
(flashing BIOS, can it help?)
Thank you very much.
Solved! Go to Solution.

Yes, I did. I have installed windows 8 (officially) and i used most of the drivers for windows. But the problem remained.
Next step I am going to do, is flashing bios.. that's probably the only thing I can do now.. (I found how to do it there:
or.. Is there any way to restore whole system to the original factory state? (I have found something about recovery discs, but I can't find those)

so.. I really didn't understand how.. but, I slovet my problem.
firstly I installed windows 7 to flash the BIOS I flashed it (http://forums.lenovo.com/t5/IdeaPad-Y-U-V-Z-and-P-series/how-can-I-get-my-money-back/td-p/920647). So now there is bios from U410 installed on my U310 (version 15). (I like this better, because upper keys functions as F1 F2 F3... and with Fn + F1... they have functions(volume...) U310 bios had it swapped)
secondly I installed Fedora 17 (UEFI mode, GPT disk tables)
thirtly I needed to install wireless adapter firmwares (yum install iwl105-firmware.noarch iwl135-firmware.noarch iwl2000-firmware.noarch iwl2030-firmware.noarch) I installed all of them. AND voila, SOLVED... I don't know how, but button is acting as supposed, fan is cooling continually and my wifi is working also.
IMO: EFI and OS are more connected than in BIOS, so badly installed firmwares/drivers can cause even hardware problems.
Thank you all, for help.
(And Fedora 17 has more battery life, than win8)
