[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.

I just noticed that this issue has been plaguing the Taichi since October 2013. Who has responsibility to fix the problem: Asus or Microsoft? Either way, 6 months seems to be an absurdly long time for such a major problem to not be addressed. This is my first Asus purchase, and the unprofessional way in which the company appears to have handled this issue means that I'm unlikely to buy an Asus product again.

Thanks so much for your help.

I don't want to run the risk of not being able to install MS security updates, so reverting to Windows 8.0 appears to be the only viable option until Asus fixes the problem. (Why are they taking so long?!).

The trouble is that I find the Asus instructions (below) confusing. They advise to NOT delete the RECOVERY partition, yet two of the three options in Step 5 will apparently do this by deleting ALL partitions from the hard disk/drive. Am I reading the Asus instructions correctly? Which of the three options in Step 5 will preserve the RECOVERY partition AND return my PC to the factory state (as if it was brand new, out of the box)?

Thanks to anyone out there who can help!

Following is from Asus website:

About the Recovery Partition

The Recovery Partition is a reserved space on your hard disk drive used to restore the operating system, drivers, and utilities installed on your Notebook PC at the factory.

IMPORTANT!

DO NOT delete the partition named RECOVERY. The Recovery Partition is created at the factory and cannot be restored if deleted. Take your Notebook PC to an authorized ASUS service center if you have problems with the recovery process.

Method One

Using the Recovery Partition(on selected models)
1. Press < F9 > during bootup.
2. Press [Enter] to select Windows Setup [EMS Enabled].
3. Select the language you want to recover and click Next.
4. Read the ASUS Preload Wizard messages and click Next.
5. Select a partition option and click Next. Partition options:
Recover Windows to first partition only.

This option deletes only the first partition and allows you to keep other partitions, and to create a new system partition as drive "C".

Recover Windows to entire HD.

This option deletes all partitions from your hard disk drive and creates a new system partition as drive "C".

Recover Windows to entire HD with two partitions.

This option deletes all partitions from your hard drive and creates two new partitions "C" (25%) and "D" (75%).
1. Follow the onscreen instructions to complete the recovery process.

Well I'm not sure if cleaning out the extra registry entries got me where I'm at, but it looks like the screen is on but backlighting isn't so its almost impossible to make out whats being displayed. Going to fiddle a little bit more.
