[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.

edit - Wasn't meant to be a reply sorry...

Could be worrying about nothing but I recently built a new computer so was comparing Windows Experience Index scores. While doing this I noticed the disk score on my Taichi has gone down from 8.15 back in March 2013 on windows 8 (I guess when it was installed as that's before I bought it), to 7.75 now under windows 8.1.

I'm not really worried about WEI scores but under 'disk metrics' the sequential read has gone down from 485mb/s to 322mb/s and random read from 419mb/s to 199mb/s. Seems a pretty big drop looking at the numbers.

Maybe it's just showing the benefits of a clean OS install but I thought an SSD shouldn't suffer as much from getting slower over time (at least for the first few years). Not sure if I have an issue somewhere or this is just to be expected.

Would be interested to know what scores other people are getting?

I gave in and installed it using a process that creates a VHDX(Virtual Partition). That way it wouldn't compromise anything and I can just remove it without and formatting. The continuum hasn't even been released in the current test version. I'd say most of the touch features in Win 10 are broken. They mainly focused so far on the UI redesign for desktop.

What Works
- Drivers installed fine.
- Screen switching works. (Slightly Buggy)
- Touch works (Slightly buggy)
- Basically all the core features of the Taichi (21 in this case)
- Desktop UI Updates
What Doesn't

(It's a Test version things are going to be broken)
- Most Hotspots (Charms bar, App Command bars)
- Search (When set to use metro touch menu)
- Continuum (Not Included)
- Touch Keyboard (Really buggy)
- Metro App Fullscreen causes apps to crash
- Other minor issues not worth mentioning
I think if they listen to all the feedback they get it will turn out fine. If not well then things will really be a mess. They will also need to follow through with the constant update schedule or I think Win 10 will probably get too buggy as new hardware is released by manufactures. Which I'm sure they realize.

I'll give an update when there is a new build.

Warning:

Unless you have advanced knowledge of computers (IT), do not install Win 10 Preview. It's for testing purposes only. It's not meant to be used by consumers or for production.

Just wanted to reiterate that .

Ha, no!

The 'continuum' mode looks like something that could work well on a Taichi though. But given windows 10 might not be out until mid 2015 I'm not sure how long we'll have to wait to have that working on the Taichi...

I still find it dissapointing most of the new models go with a fold over or detachable design (eg Yoga3 pro / T300Chi). For me; If I'm doing something quick / casual then tablet mode is perfect and there is instant access to this on the Taichi. If I needed to flip the screen 360 degrees first then I suspect I would end up just defaulting to laptop mode. If I needed to detach the keyboard then I would probably end up leaving it off and then not having it nearby when I needed it.

A thinner and lighter Taichi based on broadwell core-m could be pretty great if anyone makes one!
