Asus Transformer T100 Troubleshooting

Despite your best efforts, the tablet will not turn on.

If your power adapter is malfunctioning, the tablet will still run off the battery, but the battery will not charge. If your battery completely drains, there is no way to charge the device. The best way to test if your power adapter is bad is to borrow another T100 adaptor or find a similarly-rated power adapter to try charging your device with the new one. If the tablet battery charges with the new adapter, your original adapter is faulty and needs to be replaced.

The T100 will only charge using the original PSU (or a similar comparable PSU) and a correct micro-USB cable. It will not work with a 'charge only' cable. If you've lost your original power adapter, you'll need to replace it with the correct type.

If your tablet's battery is bad, the tablet will only run when the power adapter is plugged into the wall. If the power adapter is not plugged in, the device shuts off quickly and does not turn on. The battery will need to be replaced. Please refer to the following link for instructions on how to replace the battery for this device. Asus Transformer T100 Battery Replacement. I have found a 1A 5V USB charger that works fine, with a particular USB cable.

To check if your screen is bad, plug the power adapter to the wall and connect the tablet to it. Next to the power button on the device, an LED should light up, meaning the device is receiving power. If the device's screen still does not display anything, it is possible that the screen is functioning incorrectly. A screen replacement may be needed .

As a word of caution, screen malfunction may result from more complicated hardware issues inside the device. Understand that replacing the screen may not necessarily fix a screen display issue.

If your tablet stopped turning on after a bios update or your tablet just stopped working and you're positive it's not a hardware or OS issue then there's still hope. The power and the webcam indicator lights should still work, not that they're necessary for the fix but they do help in terms of telling you the "mode" you're in.

Fix a Corrupted BIOS on any of the Asus T100xxx laptop/tablet models:

Requirements: A separate computer that has access to the web, and a USB flash drive.

Procedure:

Step 1.1 Download your tablet-specific BIOS from Asus Download Center: www.asus.com/support/Download-Center (MAKE SURE IT'S THE SPECIFIC BIOS FILE FOR YOUR MODEL), I recommend the latest version BIOS but if for some reason you want an older version, go for it.

Step 1.2 Format your pen drive to fat32 and rename it to ASUS.

Step 1.3 Extract the bios files to your USB drive, the name should look something like this: T100___AS.xxx and the extension (.xxx) should be some numbers, in my instance, the file was called (T100TAMAS.400)

Step 1.4 Rename the file: remove the AS at the end and change the extension to .bat (if you can't change the extension check the bottom of this section, to "How to enable file extensions"). It should look like this (T100___.bat), and then you're ready to unplug your "BIOS recovery" USB drive.

End result example: (T100TAMAS.400 ---> T100TAM.bat)

# IMPORTANT precautionary steps before you continue: make sure you have the tablet plugged in, and powered off, if you're unsure if it's off: hold the power button until the power light starts flashing white and orange and then turns off, if it instantly starts flashing white then you just powered the tablet on, so repeat the procedure.

BIOS Flash: yes flashing your bios is risky, but in this case, your bios is already corrupted, so no, it's not risky.

Step 2.1 Plug in you're newly created recovery drive

Step 2.2 Press and hold the power button and the side button simultaneously, until the camera indicator light turns on and stays on.

Location of side button: on either side of your tablet

If successful a blue screen will appear that says "ASUSTeK Easy Flash Utility" at the top, the BIOS update/recovery should automatically do its thing, and you should see a progress bar. If nothing happens scroll down until you see "No Easy Flash"

Step 2.3 Wait and don't touch anything.

When the progress bar is full (BIOS flash completed), your tablet should automatically restart or it may prompt you to press any key, and then it will boot into the operating system (Windows 8.1, 10, or 11, depending on which one you've been using.) Windows should either start normally, or you will be met with a screen that says something along the lines of "repairing your PC, preparing automatic repair, (etc.)", which is 100% normal, just wait for it to finish and your tablet will be back on Windows.

No Easy Flash:

So something didn't work? okay, let's trace back our steps.

Power off your tablet and restart from step 2.1

You may have incorrectly named the bios file, restart from step 1.4

If it still doesn't work you probably need to get a new BIOS chip, or use a BIOS chip programmer:

Windows integrated customizable power settings into the software. To access these settings, click on -the battery icon on the right side of the taskbar. Then click on the link “More power options.” In the new window, there will be an option on the left side called “Create a power plan.” In the next screen, click next. You can now adjust the screen brightness options and how long the computer’s display stays on. If you reduce both of these, it conserves energy.

The original stock software for the Basic Input/Output System (BIOS) is not optimized for this device. The BIOS is responsible for finding components of the hardware and telling the operating system how to use them. By updating the BIOS software, it could help optimize the battery life. The BIOS is part of the framework of the software of a computer, so be careful and pay attention to the instructions provided. The following link explains how to update the BIOS from 2.14 (the stock system) to BIOS 2.20 (Go to post #5). BIOS 2.2 Update

When the power button is pressed in, it becomes stuck underneath the tablet's outer case.

The design of the tablet causes the power button to get stuck within the casing of the tablet. One way to regain use of the power button is to use a safety pin to center the power button. If you are unable to re-align the button, try replacing the button using our replacement guide for this device. Asus Transformer T100 Power Button Replacement Guide

The Asus Transformer won't respond to commands from the track pad.

In the original device settings, SmartGesture software is turned on for the track pad. This setting allows for different strokes on the track pad to signal a specific action. However, this can cause the device to slow down as it tries to interpret your hand motion or perform an unwanted action. To prevent this, go into your device settings and uncheck the track pad signals you don’t use. It is also possible that the track pad was turned off; this can be switched back on by pressing the Fn and F9 buttons simultaneously.

If the track pad is still unresponsive, the track pad could be broken. This is uncommon but in this case the track pad would need to be replaced.

When in use the device stops responding.

If your device freezes, try rebooting it. To do this, turn if off manually using the power button on the top of the tablet.

If your device is still freezing it might be necessary to factory reset it. Doing so will restore the device to its original settings. Items such as photos or apps saved to the device will be erased during the reset. Be sure to back up this information. For the reset, first go to settings and select backup and reset then factory data reset. For more detailed instructions go to Factory Reset.
