Satellite C660: no WLAN after BIOS update

I own a C660-115 (PSCOLE) model laptop.
Since I have performed a BIOS update (to vs 1.40) my WLAN is not functioning anymore.
I've made sure the drivers for the WLAN-card (Realtek RTL8188CE) are very much up to date.
Windows says the WLAN-card is ok ('device working properly'), but no connection can be made.
My cabled connection to the internet is working fine.
Any suggestions? Any clearcut solutions? Please?

Dear all,
> Last option is to reinstall OS and test functionality with factory settings.
Speaking of last options, this definitely is one (and not one i am going to follow).
So, just for the record: problem not solved, mystery lingers on.
Thanks for all the suggestions.
> Why you didnt post here question: should I update BIOS on my notebook?
> Believe me most of he peple would write NO. Dont change anything if the system runs properly.
Funny question .... I definitely do not want to get in a rant, but I might ask in return: why is Toshiba then offering an updated BIOS version for my model laptop, and making sure that i pay notice to this update through their pre-installed 'Toshiba Bulletin Board? "Adds increased functionality ....." , that's what it said.
So, to orund up: if there are no other options than a reinstall, consider this topic closed.

Satellite Pro L300: BSOD after BIOS update

Hi
after update the Bios of Satellite Pro L300, the windows not start!
Its show the blue dead screen!
What can i do?

Hi
Are you able to access the BIOS settings?
Im not quite sure why this BSOD appears but possibly the SATA mode settings have been changed after BIOS update
Usually the SATA mode should be set to AHCI if the SATA drivers are installed.
But if the SATA drivers are not included the SATA mode should be set to compatible.
Please check this!
Furthermore you could set the BIOS to the default settings and could try to boot the machine again.

Satellite C660 - Keyboard lag and BIOS update will not install

Hi All
Have Satellite C660 with keyboard lag issue tried to update Bios but after downloading Bios from Toshiba web site and running the intaller a message says the Bios already installed is a newer version and the install with now cancel.
Can anyone help?
Pilot

Hi,
I have exactly the same problem. I bought Satellite C660 8 months ago and the keyboard started to play up about 2 months after. I tried Fn - F11 and it worked. However, the problem reappeared and was worse. Tried the same trick with Fn - F11 but it made the problem worse.
I've tried BIOS update as most suggested. But it kept giving me error message that it was unable to update. My computer was automatically restarted though. The BIOS version that currently installed is 1.80. I also have Windows 7 reinstalled, but didn't solve the problem either.
Any help would be great.......
Thanks

Satellite Pro P200-15W: After Bios Update 1.90 fan incredibly noisy

Hi, I have a Toshiba Satellite Pro P200-15W, I've recently done a BIOS update to version 1.9 and seems to have been a big mistake :-/.
After restarting the computer I had a lot of software deconfig and now the fan has become incredibly noisy.
I have the problem with the Toshiba Vista registration software, I get this message: "Vista registration has stopped working". I've read other threads, I don't want to just disable it from the start.ini file, I'd like to actually solve the problem if there's a way.
Is there a way to change the fans configuration? I've read a Toshiba post about another notebook model that had the same problem of noisy fans after a BIOS update, they gave to that a solution with a new version of BIOS, is there a way to reverse the BIOS to the previous version? (will the restore CD be helpful for that purpose?)
Cheers
Edgard

Hi
It seems the fan table was changed and renewed in the new BIOS version and therefore the fans run ofttimes.
Why the fan table was changed?
Well, usually something like this is necessary to improve decrease the internal temperature while the CPU and GPU are running with full performance.
This helps to prevent the hardware from damage!!
Usually the Recovery CD formats the whole HDD (partitions too) and installs only the Toshiba image on the notebooks HDD.
The image contains the OS, drivers and additional software and has nothing to do with the BIOS update.
But you can try to recover the notebook to see if the software issues like "Vista registration" can be solved!
If you want to reverse the BIOS you have to contact the ASP in your country!!!
Sorry but this everything what I can suggest!
Best regards

Hi
Hmmm what to say. Sounds not good and in my opinion it looks like you have updated the notebook with a wrong BIOS or something went wrong during the BIOS update procedure
Are you 110% sure you have used the right BIOS??
It seems you will be not able to solve this issue yourself without any additional help from notebook technician.
In most cases the BIOS must be flashed again on special way
For me its clear You have to contact the ASP to get rid of this issue
Good luck and regards

Satellite Pro A300 (PSAG9E) - After BIOS update Windows doesn't boot

Reboot went fine after BIOS upgrade and Windows XP logo appears loads for few seconds then beep and reboot - last known good or start Windows normally same effect.
Rebooting back to start again - this is a brand new laptop - using BIOS from Toshibas official download site.
Pretty annoyed as trying to figure out how to refresh or downgrade BIOS.
Have taken battery and RAM out to see if I can clear it?
Any ideas anyone?

Hi
Hmm this is very strange usually if something would went wrong during the BIOS update procedure then your notebook would not boot up.
It would be dead.
But in your case the notebook boots up but just the OS does not start properly
Maybe you should try to reinstall the OS again?
I see you are using the Win XP I think the Vista was preinstalled. Am I right?
Hmm. in my opinion you should try to boot from the Toshiba recovery disk and should try to reinstall the OS in order to check if this issue could be solved.

Satellite A100-153: changes after BIOS Update V2.00

Hi Lukas
I agree with Joao. You will not find any public documents about such changes in the BIOS. I assume this information is not for a everyone.
However, I think your early BIOS updates going wrong because either you have used a wrong BIOS or a wrong BIOS update procedure.
You should know that there could be more different units and some models use different BIOS. Anyway, I think if you have no problems with your unit so I would recommend updating anything. I use my notebook for about 5 years and I have never updated the BIOS on it because it runs great.
You know that the BIOS upgrade is a little bit risky and therefore if you dont need the new version you shouldnt update it.

Satellite C660D-117 dead after Bios update

Yesterday I tried to execute bios upgrade but it got stuck in step 3 (of 27 I think).
I left it as this for more than an hour, nothing happened.
I also tried to cancel it or press CTRL+ALT+DEL but the machine was completely frozen.
It did not react when I pulled out the power cord.
Basically the only thing that I could do was to remove battery that I did. PROBLEM - now the laptop is completely dead. Not like others were saying that it boots. It does not do absolutely anything - even there are no LED lights on when I plug the power cord.
I tried to remove the battery and hold the power button for a while in order to reset the CMOS, but no luck.
It does not react at all.
Do you think it is solvable by flashing the CMOS again (if it is even possible) or do I have to purchase a new motherboard?
Thanks

> Do you think it is solvable by flashing the CMOS again (if it is even possible) or do I have to purchase a new motherboard?
Its difficult to say in most cases it should be possible to bring the notebook back to life flashing the ROM module (where BIOS is stored) once again using an crisis disk.
I dont know if this would help you but take a look into this thread:

After BIOS update DVD driver do not read DVDs anymore - Sat A80

Hi,
I have a Satellite A80-131 and after bios update (last version 2.5) by windows procedure update, my DVD drive do not read DVD medias anymore. It is possible to read CD medias, but not DVD one.
Can I reinstall the old bios? Can I reinstall the firmware?
Thanks
Ronai Lisboa

Hi Ronai
Like Jimi has said in the posting above. It's very unusual that after BIOS updating the DVD drive hasn't read the DVDs.
Furthermore it's not advisable to use any 3rd party applications to DOWNGRADE the BIOS. Usually only the ASP can downgrade the BIOS. Such procedures are very serious and the wrong procedure can damage the motherboard.
However, it's nice that you have solved the problem and that the drive works properly.
Thanks for the feedback.

After BIOS update Satellite L350-172 doesn't start anymore

Satellite L350-172 Bios-Update from bios-20090203164614 to bios-201002250
I just updatet the BIOS of my notebook from 1.60 to 2,20. Now the Notebook doesn't start any longer.
"It was stopped for reason not to damage the Computer" - blue schreen.
How can I downgrade the bios again? Or - what have I to change in the bios-settings?

Hi schuwe,
Im a little bit confused about your posting. How do you tell your BIOS not to restart?
Anyway, after BIOS update you should load the default settings in BIOS.
Did you choose the right BIOS especially for your model?

Satellite A100-590 PSAA9E freezes on Toshiba welcome screen after BIOS update

Hi.
Yesterday I did a BIOS update on my Satellite A100-590 PSAA9E-03Z00QGR with the appropriate flash:
http://eu.computers.toshiba-europe.com/cgi-bin/ToshibaCSG/download_driver_details.jsp?service=EU&selCategory =2&selFamily=2&selSeries=153&selProduct=624&langua ge=17&selOS=10&selType=all&yearupload=&monthupload =&dayupload=&useDate=null&mode=userMachines&search =&action=search&macId=&country=all&selectedLanguag e=17&type=all&page=1&ID=58477&OSID=-1&driverLanguage=42
bios-20070709111839.zip
After the flashing procedure the machine rebooted automatically, but unfortunately it now keeps hanging at the Thoshiba welcome screen. Also pressing F2 or F12 won't change anything. It seems like the BIOS is corrupt.
I saw, that in the BIOS package are delivered two flash files (s10gm590.rom and s10pm590.rom). But just executing the SanAntonion10 BIOS590MP.exe a .vbs script is started that decides automatically chooses and loads a flash file. Maybe it chose the wrong one?
What shall I do now? Is there a way to restore the BIOS, or do I have to send my notebook in?
Thanks in advance
MAT

> Satellite A100-590 PSAA9E freezes on Toshiba welcome screen after BIOS update
What to say Marc. It looks like you have used a wrong BIOS version or you have updated the BIOS in wrong way.
You could try to access the BIOS and try to set the settings to default.
Dont forget to save the settings if you will exit the BIOS.
But if this procedure does not help, you will have to contact the ASP in your country.
Possibly the guys will try to flash the BIOS again with other special version.
Good luck

Satellite Pro C850 wont work after Bios update

my satellite pro c850 cd wont work after bios update from toshiba.
what do i do?

Saying: dont work you mean it does not power up or what do you mean exactly?
Did you flash the BIOS properly?
Possibly something went wrong during the update and this means that ROM module isnt flashed properly
In most cases a special BIOS crisis disk would be needed to get it working
Not quite sure if you can get it fixed by your own
Check this thread. Maybe it helps:

Satellite L650-1KR PSK1JE - dead after BIOS update

As the subject already states, my Satellite L650 - 1KR Part No. PSK1JE is totally OFF after BIOS-Update 2.40-WIN from bios-download-page.
I tried everything: Press all buttons, take out the laptop battery, only laptop battery, ...simply nothing!
My last hope is a hidden, very special key sequence for toshiba laptops or something like this.
Of course my warranty is already over... :-(
Please help!
Thank you in advance...

Sorry to hear you have such problem now. I presume something went wrong and now the BIOS chip is screwed up and in such situation you need professional help. Toshiba service provider can help you with this but Im afraid it can be very expensive.
In the past I never had such problems but on the net you can find many pages with description what can be done. Visit this page and check if you can find something useful there. I mean you can try to fix it alone.

Satellite A series does not start up after BIOS update

After bios update with downloaded utility my notebook does not start up.
Did this case covered by warranty?

Im not quite sure if this would be covered by warranty. You should contact the ASP in your country for details but I presume its not covered.
PS: Did you try this workaround:
- remove battery, disconnect the AC adaptor
- wait ~ 40min
- connect both devices again and try to power up the notebook

I can't activate windows 8.1 pre-installed on my Toshiba E45-B4200 after BIOS Update

I bought Toshiba laptop Model E45-B4200, at first time I could activate windows 8.1 like a charm.
Few months later Windows 8.1 has crashed, so I did clean install of pre-installed windows, no problem so far. Toshiba Application installer app has downloaded BIOS update, so I ran it.
I tried to activate windows after BIOS update, but it didn`t work. No error message, but Change PC settings window just got minimized every time that I tried to click on Activate Windows option. I thought that I did some mistake, so I repeated windows reinstallation, and same problem occurred again.
Now I can`t update Windows, Office 2013, and so on.
I`ve tried SLUI 4 command to force activation by phone, but it didn`t work as well.
I read on MS blogs that windows 8.1 stores product key on MSDM table, windows should be activated normally. Now I got no options now, can you help me?

It shouldn't need to be activated it. Everything should be automatic. Because it's asking you, that's already indicative of a problem. You might want to call customer support.
