[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.

"When I used the Taichi button to switch to mode 2 (tablet only), front display remained on, but dropped down to 1024x768 while tablet display remained off."

The above is exactly what happened to me on 24th April 2014, after a software update on my newly purchased Taichi. It seems that Asus has not yet rectified the problem, which is very shameful because they've had sufficient time.

Is the best advice still to downgrade to the old graphics driver?

Thanks to all for your help and advice.

No, it isn't. Downgrading the driver leaves some functions inoperative. If you have the first 8.1 installed you should have the latest driver, 3412, installed, Close Lid 1.1.9, ATK v 1.0.0030 or later, and most importantly the latest Bios depending on model. For the 21 it's either 2.10 for earlier models or 2.04 for later 21A models. If a 31 Check Asus website for that.

So long as the later 8.1 Update which is this KB2913955 or whatever it is, is uninstalled if already loaded, and you have the packages I described here, your Taichi should work normally. Trouble is that soon you will not be able to install MS security updates which is why we need the patch to fix the latest update.

If you can't uninstall 2919355, only way to have a working Taichi is to recover to 8 and stay there. The early 8.1 upgrade that works is no longer available AFAIK.

Hope that helps...

Hi proud (and less proud) Taichi owners,

I can add a new experience to the list. On my Taichi 31, I had all problems mentioned above. Could not solve it, so in the end I did a refresh back to Win8, which, in combination with Closelid 1.1.9beta worked out fine. No bios flash.

Although I am not satisfied at all about not being able to upgrade to Win 8.1 and having to risk any update as well, I did work on my Taichi as I wanted....untill I used Powerpoint in presentation mode... It worked fine, I impressed my client with the outside screen, and made the deal.

After closing powerpoint, I could not use the outside screen anymore at all. Just the windows logo would light up. But there were no changes in drivers, software or anything else: just the usage of Powerpoint broke the outside screen feature (again).

Now I can use the outside screen, but only for Powerpoint presentations. I have no other way to the screen other than to start a presentation. That works fine, but it's bizarre that nothing else seems to work.

I'm so done with Asus (after 8 years of a loyal usage of 5 Asus devices). I fully support any initiative for European lobbying to US class action law suits. Very much.

Regards,

Jeroen
