C55T-A Touchscreen dead after Windows 8.1 Update

After updating my C55T-A5296 to Win8.1, I've lost all touchscreen functionality.
Order of operations:
1. Turn laptop on
2. Run Service Station, run all updates. This included an update to BIOS v1.20
3. Run Windows Update - Install all updatres.
4. Download Windows 8.1 from Windows Store, and install.
5. Reboot several times during install.
6. Perform initial setup in 8.1, to include Wireless config, user info, etc.
7. Run Service Station again - No new updates available.
8. No touchscreen.
9. Spend two weeks on the Internet determining that other Toshiba laptops have the same issue, and THEY got a new BIOS update to fix it.
10. Give up and call support.
11. Swear to never buy a Toshiba product again.
On the advice of support rep, I've wiped the machine back to Windows 8, and touchscreen funtionality was restored. I then went through the process of re-updating to Win 8.1, and the problem repeats.
In DevManager, I see "unknown usb device (device descriptor request failed)" I am unable to locate any TouchScreen device drivers for my model.
Anyone have any advice?

Hi CrunchyFerrett,
I have this problem before and what I ran system recovery [click HERE] as my first try. But the outcome is still the same. So I decided to send my laptop to depot to fix. If you think your laptop is in warranty contact Toshiba warranty # 1800.457.7777 business time 8am-2am the following day EST.
Hope this works for you!
BTW IF YOU THINK IT HELPS ALOT. PLEASE DONT BE AFRAID TO CLICK KUDOS star ^_^

HP Envy Touch Screen / Touchscreen dead after Windows 10 install

Tonight I upgraded from Windows 8 whereby my touchscreen worked perfectly to Windows 10 whereby my touchscreen on my HP Envy laptop is totally non-responsive. Is there a fix for this problem? Does HP have a new driver or software that will fix this problem? Is this a Microsoft problem that we have to wait until and update? I have read where others have experienced the same. I cannot imagine Microsoft not supporting touch screens since it is required in tablets, phones and many cross over laptops and computer monitors these days. Please help

Update. The Edge Browser did not work until after several shutdowns and restarts over a couple of days. It was initially "not responding." Now it is working and the touchscreen capability is working - on the Edge browser. The touchscreen capability is not working in the Chrome browser but all other functionality is.

KT6V 7021 - OnBoard NIC "dead" after BIOS 2.00 update ... any thoughts?

Hi!
Just flashed KT6V BIOS 2.00 and now my onboard nic suddenly stopped working.
The network adapter gets recognized by Windows as usual, but although I do get a dhcp lease from my server I'm unable to connect to any share on it. It's also impossible to surf the web or to simply ping any local/remote host. If I try to connect to the system from any other workstation on the lan it doesn't work either.
The network status only shows a great amount of sent packages - caused by AVAST! as it tries to look for an update on boot - but only "0" received.
I flashed the BIOS from the emergency diskette and did a CMOS clear (Jumper) afterwards. And yes, I did disconnect my PSU from the wall socket.
Since I need network access to the system I tried stepping back to BIOS 1.90 but with no avail - the onboard nic doesn't receive a single paket after it has got it's dhcp lease.
Any clue what might be wrong and how I'm able to get my nic back to work?
Thank you in advance for any useful help.

Hi Fredrik.

So if you were to downgrade BIOS problems would go away, right?
I have already downgraded to BIOS 1.90 and the problem stayed the same - the onboard nic is still dead beef.
Quote
When clearing CMOS there can be no el. left in your system, so unplug power cable etc.
As mentioned in my first post I _have_ unplugged the power cord from the wall socket.
Quote
If the new BIOS would affect NIC card... Hm, it is hard to see quite how.
I can't think of any reason either, however, the nic went dead after updating to BIOS v2.00. I assume that there must be some kind of "network code" inside the bios which has to do with the onboard nic - otherwise I'm unable to explain why the MAC address suddenly changed to "11:22:33:44:55:66". If I would only have a clue on how to access and/or flash the nic ... ???
Quote
Is there any error marks for the nic in say Device Manager, if you get that far?
Nope, there is no question or exclamation mark on the network card in the device manager. Windows thinks the card is working, but in reality it isn't. As already stated: No traffic from/to the network.

Unable to boot from ODD or USB after windows 8.1 update on P850-31L

Hi
I just updated a P850-31L to windows 8.1 from windows 8 through the windows store.
Before the update I was able to boot from a USB drive by pressing F12 during start up.
After the update I was no longer able to boot from the USB drive. Selecting the USB drive by changing the boot order in BIOS setup via F2 or by pressing F12 no longer works.
Booting from ODD is also no longer possible.
The BIOS version is 6.70 and does not allow secure boot to be disabled. However the DVD and the USB stick I tried are signed Ubuntu 12.10 which worked prior to the upgrade. Fastboot in windows 8.1 is disabled.
This would then appear to be a bug in the Toshiba BIOS? Or has the windows 8.1 updated the BIOS or the EFI boot partition in such a way as to override the BIOS setting? Really stuck here, doesn't seem to be much information about.
Any thoughts or assistance would be very much appreciated!
Thanks
Michael
Update: I just tried booting from the Toshiba windows 8 recovery DVD and this no longer works either.

OK I fixed this.
Firstly it's worth noting that it is possible to to disable secure boot in the 6.70 BIOS.
However this option is only available when the user password is not set in the security menu.
After enabling or disabling the password a reboot is required to make the secure boot enable/disable option either available or unavailable.
That's good I suppose as I guess it may prevent secure boot from being disabled when the machine is running. However this does not appear to have been related to this issue.
I selected the 'reset to factory defaults' option on the exit menu.
The machine was then able to boot from USB and DVD. The boot order was also respected.
Perhaps the windows 8.1 upgrade somehow invisibly corrupted the BIOS settings. Or maybe it was just a stranage co-incidence that the BIOS corrupted itself during the install. Either way that factory reset fixed it.

IDT High Definition (HD) Audio Driver problem after windows 8.1 update 1.

Hello. I have HP Probook 4730s. After I installed Windows 8.1 update 1 the sound driver stopped working properly. When I want to play some music, video or even system sounds, sound appears after 1-2 minutes. At that time HDD usage is 100% cause of windows audio device graph isolation. I’ve installed that IDT High Definition (HD) Audio Driver from HP’s driver support site, but that’s not working. As I see in device manager driver’s release date is 24.10.2012. I think, it’s too old for Windows 8.1. Can you help me? Is there any other newer version of that sound driver? Also I’m sending two pictures where are HDD usage and driver release date.

After Windows 8.1 update Lenovo L420 has half the WLAN speed

After the Windows 8.1 update my L420 WLan only works with 55 MBit max. In Windows 8.0 it was between 120 and 150 Mbit. I have the 1x1 11b/g/n W-LAN-PCI-Express-Half-Mini-Card-Adapter. Lenovo L420 is 7854-4LG.
The WLAN driver is a Microsoft driver as in Windows 8 but a newer version.
How can I get the Windows 8 driver back?
Why doesn't provide Lenovo a driver as with Windows 7?
Is Lenovo not testing any of their Laptops for compatibility?
Any help?
Michael
Solved!
Go to Solution.

I found a solution in the meantime: I loaded the driver for the RTL8188CE chipset from the REALTEK site.
Now I'm back between 120 and 150 MBit.

Slow after windows 8.1 update

I have recently done the windows 8.1 update on my laptop and now for some reason when ever i boot the laptop up it takes forever to load. before the update the laptop booted in about 17s but after it takes more like 30s. i tried solving this problem myself but haven’t had much luck. what i have found that if i uninstall or disable my Intel HD graphics 4000 card it seems to solve the problem but i need my graphics card on the play some games etc. so my thought is it must be a hardware problem or a driver problem.
Can anyone help??

Hello MooreMoose, welcome to the HP forums.
It appears that your notebook is slow too start up after an update. I will try to help you with this.
Start by doing a clean boot. This will have you disable start-up items and services that aren't essential to have running when the computer first starts.
This could also help in determining if an application is behind the slowness. If the behavior continues, then it would be something updated or the OS. If this is the case, please start by doing a system restore. I recommend doing a restore from safe mode, to ensure it goes through correctly.
I will leave you to start with this, please let me know how everything goes.
Thank you for posting on the HP forums.

MSI GT70 audio not working with hmdi after windows 8.1 update

When I connect my laptop to the TV, the video comes out fine, but the audio for the TV does not show up in playback devices. It worked fine with windows 8, but after the windows 8.1 update it stopped.
I have tried updating realtek drivers, but it still doesn't show up. updating other drivers also doesn't work. plugging the cable into the computer then booting it up also doesn't work like it did for other people. This is really making me mad... any help would be appreciated.

Pah, no probs to my ext. monitor speakers via HDMI, GT70 0NE, Win 8.1.
Have you tried assigning HDMI one on audio tab as default and see if sound will come out to tv? if so then that was the problem.

Qosmio F60-11C - Black screen after Windows 7 Directx11 Update

Hello,
Two days ago I updated Directx version because that i want to try Call of Duty Black Ops on my notebook. I updated normally and it works perfect but after a day, on Windows7 reboot, after Windows 7 logo, i have a black screen and cpu fan works at full speed. So i used Toshiba Recovery Center and i recovered my pc to fabricate settings. When it installs drivers it crashed on Graphics driver again. After that, i installed Windows 7, but im using my computer on 640x480 resolution with 8-color.. And i can use Security mode with network but if i install GT-330M driver and reboot computer, it crashes on after windows 7 reboot.
I have tried to change options in the bios but it's always the same problem.
*My Graphics card :* Nvidia GT330M
*Bios Version :* 2.50 / EC2.40 (last update on Toshiba website)
*Nvidia Driver :* 260.64
I downloaded 197.16, 197.71, 258.80 drivers from Nvidia and laptopvideo2go, but when i try to install these versions, it says not compotible with my system settings.
Im totally crushed now and i dont wanna give my laptop to Toshiba Technical Service which is in Turkey. For Easy solution they spent 30 days..
Do you have a idea?
Thank you in advance
Aras.

I had same problems after installation the OS from recovery disks. It wont open after installed graphic card driver.
I forced windows to install alternative drivers but again it wont work.

I installed the drivers as same method that u said.. it wont work..

8625 stopped printing after windows 8.1 update

my printer has been working without any problems until there was a windows 8.1 update on feb 11. it just stopped printing from my dell laptop. the print job appears to be added to the queue and it spools, but then nothing happens and there are no error messages. it still works from my iphone/ipad and it prints when i send a document to the printer email address. just not straight from the computer. i have updated EVERYTHING on the laptop. i have uninstalled/reinstalled the printer software several times. i have uninstalled all of the windows updates from feb 11, 2015. nothing works. i'm not super techy. i assumed a driver was missing or something wasn't compatible from the update so those are the fixes i've tried. and in the process i've messed something up so now not all links work in internet explorer. i've now been working on this since sunday. help!!!!

Hi @deannesab
I would certainly be happy to help you with your Officejet 8625. I understand you are no longer able to print since updating to Windows 8.1 and that you can still print from other devices such as your iPhone and iPad.

Dead Keys on Lenovo W520 built-in keyboard after Windows 7 (64bit) Update

After my Windows 7 update, I have several dead keys. Left Alt, Up Arrow, Print Screen, F5, F6, and the ThinkVantage Keys are all dead. Orginally I thought it was just Windows, but after booting into my Linux OS, I run into the same issues. I have tried reflashing my bios, but that did not fix the problem. Can anyone help?
Hardware: Lenovo W520 (Referbished)
OS: Windows 7 (64bit), Debian Linux (64bit)
Age: 2 months after refurbished
Update 1: Chrome and Firefox would crash if I tried to download something. Did a system restore which fixed the problems with that, but there are still dead keys. I am now downloading a bootable cd from Lenovo. If that fails, I will attempt to reflash one last time before I send this thing to get fixed by the pros.
Update 2: Just remember, why would the lights in the keyboard stop working? They keys still work, but the mike key and the caps key are not lighting up their LEDs when I'm using them.

Touchscreen quit working on P55t-A5202 after Windows 8.1 update

I updated to Windows 8.1 and my touchscreen quit working. I have avoided all updates on Toshiba, but have just installed 7 of them including bios update hoping to fix the problem. No help! Still no touch screen. Went to help forum...told to uninstall the human interface device drives on my laptop and reload them. Did that to NO avail..still doesn't work! HELP! Was hoping Windows 10 would auto fix but I truly doubt it!!! Can anyone help me please?

Hi P.Ava,
Thanks for the reply.
What is the error do you get during the launch.
Did you try to launch from the C:\Program Files\Adobe\Adobe Premiere Pro CC\Adobe Premiere Pro.exe
and
Please tell us more about your system :
What is your exact graphics adapter driver version?
Have you gone to the vendor web site to check for a newer driver?
For Windows, do NOT rely on Windows Update to have current driver information
-you need to go direct to the vendor web site and check updates for yourself

Re: HP Pavilion 11 - x360 touchscreen not working after windows 8.1 update

Having the same problem with the same Laptop. Yes, full shutdown, numerous times. All Windows Updates addressed. First problem is that there is no programme installed called "Tablet PC Settings" - probably because it's not a tablet ? When I go to Perform UEFI Hardware Diagnostics tests to detect problems with the notebook touch screen hardware. This tells me there is no problem with the hardware, so it seems to suggest it's a software issue. I am loathe to do an entire system restore based on something that should probably be easily solvable.

Hi again riceuten, Thank you for the quick reply! All notebooks with Windows 8 feature Tablet PC settings and other touch screen-related features, regardless of whether the notebook features a touch screen. This is used as an operating system default. If you have already attempted to configure the touch display, and enabled the touch screen driver in Device Manager, then the only remaining step is to perform an HP System Recovery on your computer. This will help rule out any remaining software issues that may be contributing to this issue. This can be done by following the steps in this resource on
Backing Up Your Files (Windows 8), as well as Performing an HP system recovery (Windows 8). This should return your system back to factory defaults.
If the issue continues, please contact our technical support for further assistance in this matter by clicking the link below to get the support number for your region.
www.hp.com/contacthp/ If you select "United Kingdom", and enter the product number of your notebook in the search box to the right, it should come up with the necessary contact information.
