[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/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.

Has anyone tried the 5/12/14 Windows 8.1.1 Update yet? (KB2955164.)

Update Details

Hi, yes I installed it on a Taichi 21A a week ago and it seems to work fine.

(I use latest Bios and all latest drivers except for VGA, where I use the 9.17 driver because the upside down mirror mode.)

Cheers //Per

Hi,

I have been through all the same heartaches and hassles as the other members of this forum and after installing the new BIOS (205 for my Taichi 21a), I found that the performance of the machine had become slow and sticky, also if I left the machine idle for a while, the window that had focus would lose focus for a second, blink and regain focus.

A little bit of web searching led me to the windows event manager where I found that the IGFXEXT process was crashing and restarting every few seconds. This process is part of the Intel’s display driver tray program, which I can happily live without. I disabled all process related to this in the Startup tab on the Task Manager and now my machine is much faster without any noticeable impairments.

Hope this helps some other people.

Update Details

I'm afraid to update it because it seems like every time I do, my pathetic excuse for laptap keeps breaking. Currently my Taichi21 is running at an acceptable level, (not great, but not terrible) with the suggested bios updates provided earlier in this thread that corrected the March fiasco which broke my laptop after updating Windows 8.1 to 8.1.1

As a side note, I cannot in good conscious ever buy another Asus machine ever again. Overheating problems, extremely poor drivers that cause my keyboard backlight to go on and off while typing, and the list goes on. Had to RMA twice now and will have to RMA it again pretty soon as well because something inside the fan mechanism keeps overheating and a piece of plastic breaks off and starts rattling around inside. Truly, a terrible waste of $1000-$1300 depending on where you bought it from.

Sorry for the rant. I feel better now. :)
