NO Sound after Bios Upgrade

After updating Bios to version 2.00 there's no sound through Speaker if I switch to headphones, sound it's OK. If I suspend the PC, sound its back for almost 5 or 10 minutes then it goes.
If in Smart Audio app, I switch audio mode from Classic to Multi Stream, sound its back but after sometime it goes, just like if I suspend the PC. SO I think it's not an Speaker Issue.
PS: Tried reinstalling Audio Driver but no Luck same Problem.
The Laptop is a:
Toshiba Satellite C645-SP4131L
No Hardware Upgrade
Win 8 Pro (Clean Install) (Drivers are from Toshiba One Click Upgrade) (This problem also occurs in Win 7 and a Live CD of Ubuntu)

The only way to know for sure if it's a hardware or software issue is to try a system recovery. If the problem persists, you'll know it's a hardware issue (including a BIOS issue).

Help Please - X200 will not boot after Bios Upgrade - keeps asking for power on password

Hi there,
I am new to this forum and please let me say a big Thank You for your help in advance.
I am using a lenovo thinkpad x200 running windows vista with service pack 1.
The laptop has always been running fine and has never given me any issues. Unfortunately, all this came to an end yesterday when I ran the system assistant which did a round of updates and it prompted me to reflash my bios.
I did what was instructed and closed all open applications and after the laptop restarted, there was a noise from the harddisk (the sound was basically like what happens if the harddisk suddenly loses power). Then, all i got was a black screen, no harddisk acitvity with only the power cable LED and another LED (with the shape of a N tiled at 20 degrees) on.
I searched the forum and did what was suggested in this entry: http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/Blank-screen-after-Bios-Upgrade-on-X200/ta-p/29...
This is what I did so far"
I turned off the power, took out the backup battery and waited for about 30 minutes (repeated this step several times, also removing the harddisk) but to no avail.
I removed the RAM and tried booting and there was that characteristic beeping sound.
I replaced the RAM, redid the CMOS clearing, and now there is the Lenovo startup screen. However, there would be an error code 0271 (no date time) and 0251 (something about default configuration). Then, these disappear and all I am left with is the Bios Power On password prompt. Somehow no matter what I type nothing can be input into the field (and I did not create any password as far as I can remember).
I redid the clearing for the power on password by removing the backup battery as suggested at the bottom of this page http://support.lenovo.com/en_US/detail.page?LegacyDocID=migr-59377 but it is no use. Each time I restart, even if I press the blue Think Vantage button or F1 or F11, I still get the same 0271 and 0251 error messages and am left with the power on password prompt.
I am really desperate as I really like my lenovo x200 and there is important data on the laptop. I would appreciate any suggestions on how I can solve this. Its amazing how a simple update can turn into such a disaster. Now i know i should never upgrade or update my Bios (or at least proceed with extreme caution).
Anyone can provide some help to get my laptop workin again?
Thank you very much,
Mark

try reflashing your bios?

Why My iPhone 4 doesn't have sound after I upgrade it to IOS 7.0.2

Why My iPhone 4 doesn't have sound after I upgrade it to IOS 7.0.2?

Try this - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.) No data/files will be erased.

K7n2-L wont boot after bios upgrade

I have been very happy with the motherboard since i bought it in april 2003, been very stable and only had minor usb problems. And i finally decided to upgrade the bios from v. 3.7 to v. 4.1.
After the upgrade the machine boots up to the first windows that shows me the memory and the hard disk i have installed. I can also go into BIOS.
But the PC stops when its about to start booting up the HD or CDrom. According to the lights on the D-Bracket its trying to initializing the floppy controller.
There has never been a floppy drive in this PC before(i booted the PC on CDROM when i upgraded the BIOS).
I have tried the following things without success;
installed a floppy drive.
Cleared the CMOS(with the jumper)
Unplugged the cdrom and the hard disk.
Tried every memory configuration.
jumped the safe mode jumper.
It seems to me that i can only fix this by changing the BIOS chip....or the mainboard.
Anyone had this problem?

Azraeliz,
Sounds to me like perhaps you've overlooked a setting in the BIOS
Did you take note of the BIOS settings prior to flashing so you could put the settings back the way they were?
nuckelavee,
I suggest you start your own thread. I have a hard time believing there is no CMOS jumper.
Tried this? ***Starting your K7N2 Delta2 at default settings***

External USB keyboard does not work with T60 after BIOS upgrade

External USB keyboard does not work properly with T60 after 2.26-1.07 BIOS upgrade.
It does the same with or without the docking station.
Anyone else bumped into this problem yet?
Has someone found any fixes for this?

Hi and welcome the forum!
Try uninstalling all USB hub devices from the device manager and reinstalling them again, particularly the keyboard's.
v2.26 is supposed to fix the issue according to lenovo:- http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-63024

G50-30 System is unstable after BIOS upgrade

After installing Windows 7 I decided to upgrade BIOS and picked the proposed update for Windows 7 64bit (http://support.lenovo.com/uu/en/products/laptops-and-netbooks/lenovo-g-series-laptops/g50-30-notebook-lenovo).
After applying the upgrade system boot failed. This issue was fixed using yapha7's advice (see this thread: https://forums.lenovo.com/t5/Lenovo-B-and-G-Series-Notebooks/Lenovo-G50-30-Bios-update-crashed-installed-win-7/m-p/1693051#M32265).
Well, OS boots. But now I can draw violet lines on a viewport by pressing two mouse buttons simultaneously. WLAN breaks periodically, gets fixed by a reconnection. CPU consumption increases without any resorce-intensive task being launched. It iss understood that latter two issues might not be related to a BIOS upgrade. But they all appeared shortly after the upgrade.
Also it is not clear if I'm able to use USB 3.0?
The current BIOS version is A7CN47WW. Is it possible to rollback? Can you provide the original / any stable BIOS version (for Lenovo G50-30 Windows 7 x64) which is prior to the one available at the drivers download page? Thank you!

hi a_demenkov,
Just to check, have you considered reinstalling Win7 after you got the issues that you described after flashing the BIOs to v47?
If you're leaning towards downgrading to the BIOS to v45, try the following:
1. Boot into the BIOs and enable BIOS Back Flash.
- Sample image
2. The BIOS v45 download link is not listed but if you look at the the BIOS v47 file below, you should be able to get v45 by renaming:
BIOS v47
https://download.lenovo.com/consumer/mobiles/a7cn47ww_64.exe
to
BIOS v45
https://download.lenovo.com/consumer/mobiles/a7cn45ww_64.exe
If you're not able to flash the BIOS inside Windows then you may need to do it under DOS.

X79A-GD45 windows 7 freezes during boot after bios upgrade/usb 3.0 drivers inst.

Hello,
After I upgraded my bios from 1.3 to 1.4 I noticed I still had some not properly installed hardware in the computer management screen, so I used live update 5 and found the the Renesas USB3.0 Drivers. The system runs fine, except from a cold start.
When starting the machine, windows freezes on the 4 colour logo, before the usb initializes (this I can tell from the keyboard not lighting up).
A forced reboot does not help. However, going in the bios (to check if all drives are functional) and then booting, does. After this the machine runs fine again.
Now my question is, is this caused by the new bios or by the Renesas USB3.0 Drivers? Or is it something completely different?
Thanks a lot,
Floris

Using LU5 often ends up this way doing UEFI/BIOS updates dead board!
In the future, recommend to use the forum flasher found here with instructions on how to use it; https://forum-en.msi.com/index.php?topic=108079.0
After a flash, it is also recommended to remove the power cord from the PSU, remove the battery for awhile, clear CMOS & reset.

Crackling sounds after 761 upgrade

The crackling sounds are still there after an upgrade to 761. This is very dissapointing.

OK. Thank you for your answers. We will see if there will be a solution to this annoying problem. (I have seen in privious posts under the subject Problem: Notification Sounds and Ringtones that this would be solved in the next upgrade after .757 (ref. Richard from Sony)).

KT3 Ultra2 FSB speed after BIOS upgrade

I have just upgraded the BIOS on my KT3 Ultra2 mainboard. On the CPU Support page, it says my mainboard support CPUs with FSB @ 333 MHz with the newest BIOS, but in the manual it says that the FSB is @ 200/266 MHz. Did the BIOS upgrade increase the FSB so that the FSB now is @ 200/266/333 MHz?

it increased the options,you still have to set it after flashing though

X120e: Suspend problems after BIOS upgrade.

I have a ThinkPad X120e (0596RZ6), which had BIOS version 1.08, that I have upgraded to 1.16 (8FET32WW).
I used a CD-ROM to upgrade the BIOS (8fuj09uc.iso) and all went smoothly.
Now, whenever I try to suspend to RAM while running on battery, it visibly suspends, cannot resume, and drains the battery as quickly as it would while running normally.
It worked just fine with 1.08, and nothing has changed in the OS that could break it.

The problem persists after downleveling the BIOS to 1.11. Older versions do not seem to be available for download.
Please, for the love of God, if you release a BIOS upgrade without properly testing it, then state so clearly so that people do not waste their resources such on frustrating "upgrades."

After BIOS upgrade only PCI Vid works, not PCI-e

After upgrading the bios to the most recent 1.4 version I can only get a PCI video card to work. Every time I put in my X600 PCI-E card I get no post. I have tried messing with the PCI-E voltage up to 1.7. Have tried reseating quite a few times. Have everything unplugged except 1 stick o' RAM, PSU, Proc, Video. Cleared the CMOS using the remove battery, power, jumper, etc. method as posted. Just can't figure it out. Worked fine before the BIOS upgrade except for Core Center causing reboots and CPU temp looking way too high even for a prescott.
Good news is my CPU temp is more reasonable and Core Center is working.

WEll im not going to upgrade to the 1.4 BIOS as I have the same video card. Maybe try it when I get my new X800 XL, but this is ->

Lil problem after bios upgrade/flashing

I have a K9N neo nvidia nforce 550 mainboard and found a new bios upgrade from the msi website using the express download. Ever since ive upgraded, right after startup i get a message in windows saying it found a new PCI device and that i need to install a driver for it, i have 3 pci devices installed rbefore upgrading bios (GPU, Soundcard and wlan card) and theyre all working right now, i have no idea what pci device my pc has found because there is absolutely nothing installed other than those 3. ???
Any feedback would be much appreciated, thank you

Quote from: Ithiot on 05-March-07, 01:40:20
OK so i installed one of the drivers from the express download function, it was realtec audio device driver (or something), i installed that. but sstill wierd since i dont have that in any pci slot, anyways, im not getting the popup asking me to install unknown device anymore.
(AMD away driver wouldnt install for some reason, had an error, so i think im gonna leave it at that for now, i dont want any more problems lol...)
re install chipset drivers, after that if still yellow devices left use program above to ID.

Satellite L300 - webcam doesn't work after BIOS upgrade

I recently upgraded BIOS to 2.2 and the webcam has stopped working. It disappeared and there is one unknown device in the device manager in the universal serial bus controller.
I tried everything even with new clean fresh Vista OS but nothing like there is no webcam I installed the drivers but not recognized so I would like if I can to downgrade BIOS to 1.5 and to fix the webcam. If I can cos I need it. Is that possible?
Tnx

Hi
I dont think its BIOS issue.
First of all the unknown device (webcam) appears in the device manager and this means that an device has been recognized by system and BIOS.
The only reason why its listed as unknown devices is: the driver is not installed properly.
After BIOS update you have to set the BIOS back to default. Access BIOS pressing F2 and within the BIOS you can use the button F9 to set it to default and F10 to save the changes.
After that you should boot up the unit and should go to device manager.
Mark the unknown device and delete it from the list (if possible)
Go to control panel -> software and check the software list for webcam software (from chicony). Uninstall this software if its part of the list.
Now reboot the notebook.
Clean the OS using CCleaner and install the correct webcam software for Vista. Note: please pay attention to 32bit or 64bit version.
If the installation would fail, try the Toshiba recovery disk and set the notebook back to factory settings.
By the way: BIOS downgrade is not possible because the old BIOS is not downloadable.

Satellite Pro L300 doesn't reboot after BIOS upgrade from TOSHIBA Site

After a BIOS upgrade made under windows,my system doesn't reboot any more.F2,F8 keys are ineffective at power up time.The screen remains black and there is only some permanent accesses to the CD/DVD reader.
Can somebody explained me what has happended and how to repair if possible? Must i reflash the BIOS or something else.
Thanks a lot

In my opinion something went wrong during the update and the ROM module has not been flashed properly.
According to people here in the forum, only an Toshiba service agent can help you.
But I found an interesting thread here in the forum which might be helpful to you.

Not booting after BIOS upgrade in T500

I upgraded my T500 from BIOS 3.09 to 3.18 using the windows upgrade utility (6fuj42us.exe?). The upgrade went fine. I rebooted the machine and got the login windows screen (I have windows XP professional). However, the instructions of the BIOS upgrade called to enter into the BIOS and press the F9 key in order to set all the system defaults. After that the machine did not boot. It gives me the initial windows booting screen (windows flags) and then a blue screeen. I downgraded the BIOS to 3.15 using the bootable CD utility (6fuj39uc.iso?). The downgrade went fine. I can get into the BIOS but have exactly the same problem when loading windows. Unfortunately I could not find a similar bootable program for BIOS 3.09 only the windows executable program (6fuj34us.exe?). Is there any fix other than reinstalling windows? Thanks.

Hi malope,
please enter the Bios and check the HDD is switched to compatible mode instead of AHCI Mode.
Maybe than you can start Windows.
