[UNSOLVED] Asus Taichi back screen (lid) not working AGAIN after windows 8.1 update 1

Anonymous

JP8851 has provided a new BIOS version for people who have the Taichi21 or 21a (answer marked below) . The BIOS version is not official yet, however, and many users are reporting problems with the BIOS update such as USB problems, pen digitizer problems and audio problems. Therfore I have still marked this problem unsolved, but the first answer below may work for you.

Original question:

THIS IS A PROBLEM YET AGAIN.

ASUS, MICROSOFT, AND INTEL: HUNDREDS (IF NOT THOUSANDS) OF USERS ARE FRUSTRATED BY YOUR LACK OF SUPPORT AND COMPATIBILITY CHECKS WITH EVERY UPDATE. WHY SHOULD A $1000+ LAPTOP BE NEGLECTED THE PROPER "V.I.P." SUPPORT WE WERE PROMISED? PLEASE FIX THIS PROMPTLY, IT IS FRUSTRATING FOR THE USERS TO FIGURE OUT WHAT GOES WRONG EVERY TIME WINDOWS UPDATES.

Note:

Previously, the Asus Taichi had problems with the back screen not working after the windows 8.1 update. Recently, Micrsosoft released a NEW UPDATE that ruined the fix mentioned below, and all the supposedly long term fixes Asus made with the bios updates and the graphics driver updates.

This problem had originally been solved for windows 8.1 (without update 1) by downloading the following old graphics driver from the asus website:

http://dlcdnet.asus.com/pub/ASUS/nb/DriversForWin8/VGA/VGA_Intel_Taichi_Win7_64_Win8_64_Z917102857.zip

***It is noted that if the problem keeps coming back after installing this driver, you may have to change your Windows and Intel Driver update setting and turn off auto updating.

Other notes: This driver downgrade solves the issue with the lid not working, but some users have reported that many smaller problems arise after downgrading. Therefore, this solution is not completely stable, but it is a lot better than any other solution currently available and solves the main issue.

Original comments: After updating to windows 8.1, the back screen of my Asus Taichi does not work properly. After doing some searching, I read there were numerous problems with the Taichi after the update, all driver related.

This is great news... Glad it's working with Intel 3412 as I have that installed already on my 21A. If Asus send out the new Bios for the 21A I will share it and ask the same from anyone who receives it please.

Well people, ASUS has come through with the new Bios for Taichi 21 & 21A. They emailed me the zip files this afternoon. Took me a couple hours to backup and test before posting.

The 21 takes Bios 211 and 21A takes 205. I've uploaded them here:

https://www.dropbox.com/s/mxb1trbbctlnjm3/TAICHI21AS.211.zip

https://www.dropbox.com/s/5ztcmga0mbv40i5/TAICHI21AAS.205.zip

To check which Bios you need if you haven't checked already is to reboot and press F2 until you see the Bios screen. When displayed, press F12 and the Bios you have will scroll through in the lower right hand corner of the screen. Use the 2420 version of Winflash from the Asus support site.

After flashing the firmware Bios to 205 on my 21A, I installed 8.1 Update from Windows Update and my screen is working correctly.

Thumbs up Asus.

Ironically the Bios was dated 21/4/14. Seems Asus has had this fix for a while and probably testing before releasing so I don't feel like a guinea pig. But I do feel some of you owe Asus a small apology for some of the comments aimed at them despite it taking too long to come through. In any case, I'm not reactivating auto-updates in Windows Updates.

Good luck people and the usual disclaimer applies to using these files. Caveat Emptor...

I had the same problem. It started after some time. Twice I've tried to install and the same problem.

After a long hard working weekend I moved again to win 8 and stay there for now.

P.s: it is not the only issue unresolved. Juniper concoction disconnecting is another.

What a mess..

I agree, this update is a complete mess. I was able to resolve the issue with the lid by downloading an old graphics driver from the asus website. Heres the link to download the driver: http://dlcdnet.asus.com/pub/ASUS/nb/DriversForWin8/VGA/VGA_Intel_Taichi_Win7_64_Win8_64_Z917102857.zip

The driver is older, so if you would rather just reinstall windows 8, I found that you just do a restore or refresh in the system settings. Thanks for your help again.

***It is noted that if the problem keeps coming back after installing this driver, you may have to change your Windows and Intel Driver update setting and turn off auto updating.

Good news. I did nothing that I know of, the machine is up to date on Windows 8.1, no removals and yesterday the flip screen popped into life. Just like that. I did check the latest Asus upgrades were down loaded some day ago and I suppose it is possible I had not got the flip screen switch on the right side on properly, but not to my knowledge.

When I open the lid it transfers to the main screen, but not back again, the blue switch doesn't do anything and there are a number of other remaining faults, like no autorotate (no rotate at all). But we are moving forward.

Oh, joy.

I saw this just now on Tom's Hardware site: http://www.tomshardware.com/answers/id-1657434/windows-update-touch-screen-working.html Where this user has another workaround. It's way too late for me to try now, but I'll have a go tomorrow.

I did't try either. I'll try maybe tomorrow, but meanwhile I copy below the text from the reference given by Michael:

""...I finally stumbled upon the solutions to both forms of touch screen failure - the failure upon closing the lid and more semi-permanent failure - are both caused by simple, stupid bugs arising from the particular combination of Asus' touch screen interface design and Windows' USB power management algorithms. If your touch screen is going out when you close the lid, you probably have set the computer's power settings so that it "does nothing" upon closing the lid. Changing this setting to "sleep" - after first restoring touch functionality, of course - fixed the problem instantly and permanently for me, though this will probably only work if you first go into the Windows Device Manager and find the touch screen device - it's a "USB Input Device" under the "Human Interface Devices" heading - right click and go to "Properties", go to the "Power Management" tab, and uncheck "Allow the computer to turn off this device to save power". The more permanent-seeming touch screen failure was instantly resolved by disabling the "USB Selective Suspend" feature in the power settings and cold-booting. So if you're having touch screen problems, chances are excellent that your touch screen is actually fine, and all you need to do is change all the settings as I've indicated here, cold-booting first if necessary to bring the touch screen back to life before you start. Hope this helps someone! " "
