S205 new Bios version 22 broke Bluetooth

[Romagnolo1973]

First of all sorry for my english, i'm italian

In 2 Lenovo S205 (Italian version with 3gb ram & 320gb HD) with Seven HP 64bit, new Bios UEFI version posted in the Lenovo driver page (version 22 release date 27 july 2011) broke the BlueTooth 2.1 on the 2 machine

It is not more detected in system or in printer&dispositives, it is simply disapperaed

With previous version 21 everithig was ok

I make this post hoping someoane Lenovo developer try to see the issue and update new stable and better bios ASAP

The BT was not active at the moment of my bios update but it was saw correctly on system, now is disappeared

I try to go on BIOS setting to activate but bios is realy poor, you can oly set ide or ahci HD and make hd first read on boot, no moro of that

Please Lenovo make a new and better bios asap thanks abd if possible make bios more costumizable

press f2 to load bios and set default settings, save and exit.
also, try to re-install power management, press fn + f5 to activate bluetooth. ( first switch the wireless button )

Thanks for your interesting in this ssue

I try all you suggested but suddenly it does nothing

The only detected device is wirelless card, BT stll continue missed, ven after uninstall EnergyMnagement & reinstall, even if i set default value on bios

If i try to install BT drivers it said there is no device on the pc

It's a buggy Bios in the dowload site, they don't try it on a real S205

I hope some lenovo tech watching here and solve asap

In an italian forum about S205 everyone tath update bios is in the same situation, no BT detected, so is not my personal issue, everyone have BT disable at the time of the update

Same problem here.
After updating the bios from Lenovo site bluetooth has disappeared
I tried all the suggested solutions without success, the BT device seems physically disappeared.
I'm italian too and I have the same Lenovo model of Romagnolo1973.
I hope this problem will be solved soon with a new version of bios that worked in all its parts, it is very annoying having the BT broke after an official Bios update .

have you tried to activate wireless in bios?

wireless working properly? 

i'll contact lenovo staffs about this issue. maybe, as you said, there's something wrong with the bios update and if you're right, they'll publish new bios update asap.

Hi

winphlash wrote a BIOS.BAK save your previous installed BIOS to hdd where flashfolder is located c:\winflash

that gave you the possibity to re-roll your BIOS ...

...if that happen try to flash the previous version download BIOS S205 Vs.21 

or when you didnt delete the folder  use BIOS.BAK (could be re-named BIOS1.WPH) to re-roll BIOS

Update :

 :... have taken a new pic from actual UEFI Winflash program

if you have set to backup BIOS and flash ..you have the possible backup..  otherwise not ....

First of all thanks for the answers .

to ygit:

Yep, wireless is enabled in bios and it is working withouth no problem.

to KalvinKlein:

Uh, that's an option try to roll back to the previous bios, I will give it a try, hoping Lenovo will release soon a new Bios working with BT.

Edit: I didnt backpup the last bios...I feel so noob.

...if that happen

try to flash the previous version download here BIOS S205 Vs.21 

simply re-flash with the 21 version ..that should be revoke BT back to life

a german user confirmed that it does ..

we have already contacted lenovo staffs and waiting for bios solution. ( may take couple of days to respond )

It would be nice if you remove a piece of software that breaks the functionality of your hardware from your official download section. Holding software with a known issue on your site is not the way a respected firm should work.
