[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.

Ok, but we can't do the update, and she brings new features, so, problem not solved.

Thanks anyway.

It would seem, from what I have heard here and my own experience, that where Asus have removed the restore partition off the disc so that the user cannot restore W8, KB2919355 does not give the uninstall option. It cannot be uninstalled.

Why on earth Asus should pull this trick escapes me, but I promise that is what they did to my machine and, I gather, a number of others. So, unfortunately, your solution does not work in every case.

Incidentally, a chap from MS was asking up here what, exactly were the symptoms that drew anyone to the conclusion that KB2919355 was at fault. I do not know, merely looking to follow the herd, and failing. Perhaps you could write down why KB2919355 is suspected?

The solution I found trough copy pasting solutions I collected trough forums of dissatisfied clients (be it the 21 version or like mine the 31 version )in the couple of hours after it happened is the following:

BE WARE, APPARENTLY NOT THE BEST OUT THERE, BUT IT DOES WORK 100%
1. Install older driver for graphics (http://dlsvr04.asus.com/pub/ASUS/nb/DriversForWin8/VGA/VGA_Intel_Taichi_Win7_64_Win8_64_Z917102857.zip)
2. Delete last update from windows (KB2919355) - how: left side screen - search - type: control panel - chose "programs" - right side screen, second option, so click on the one with updates in it - right click on mentioned update and click un-install.
3. Restart pc
4. If problem not solved use step 2, but uninstall last Intel driver
5. Redo step 1.
6. Restart pc
At this point the 31 version is "fixed" in the sense the touchscreen works again, only negative side effect is when internet is open with multiple screens it is no longer visually shown by Screen-caps, but just the site title (if anyone knows how to get the former back, I am listening with much interest by the way ....).

The rest is the same and works perfectly.

Again ... there are probably better ways out there, so keep looking for a perfect solution, and keep me posted as well, but in the mean time, I can confirm this works and it takes max(download included - for Europe at least) 30 minutes.

hope this can at least be of some help ....

And a good evening to you all
