[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.

Hello MBings,

Could you walk me through what you did to your 31? I still can not get my working correctly.

Thanks!

Hi

Please see below for steps I have taken with my Taichi 31, big thanks to all those that gave the tips. Main steps to get screen switching working as below (may not be the best order but I think more or less as I dod it);
- Install all windows updates
- Update to latest bios from Asus site (209 for Taichi 31)
- Run DDU from safe mode to fully remove vga driver (display driver uninstaller available from Guru3d)
- DDU should finish and restart windows, then install latest 3412 vga driver from Asus site
- Update Asus close lid if needed to either 1.1.8 (Asus site) or beta 1.1.9 (in forum thread) – after trying both I find 1.1.9 a bit better but could be imagining it.
- Update ATKACPI if needed (1.0.0030 for Taichi 31)
- Just for good measure I also updated other apps like Asus Taichi Home and Display Control etc to the latest versions.
I do still get occasional issues with screen switching, usually either display not coming back on outer panel or touch pad not working with inner panel. Pretty infrequent but still annoying. On a hunch I have tried disabling auto power on when opening lid in bios. Reason for trying was my girlfriend seems to run into bugs more often than me but she tends to use it predominantly as a laptop. Waiting to see if this helps or not…

Other items in case of interest:
- I installed Asus backtracker and made a recovery usb drive, then deleted recovery partition to give more space on SSD.
- I also - probably a bit recklessly - deleted intel rapid start partition on SSD as didn’t think I needed this (probably useful for others though). However my computer doesn’t always go to sleep automatically so I’m going to try to properly uninstall / disable RST and InstantOn when I get round to it incase it's the cause.
- I uninstalled power4gear as it’s default setting appeared to be throttling my processor a lot on battery. I’d rather have the performance and battery life doesn’t seem to have suffered that much going to windows balanced power settings.
- Following reports of screens cracking I’m now being as gentle as possible with the lid which I note is already a bit bent and doesn’t sit flush when closed (probably around 15months old now).
Cheers
