    This is a hardware problem - pure and simple. This is caused by faulty electrical design in the power, backlight, and digitizer systems. There is an electrical short that occurs if the backlight is turned on at all - infrequent at lower brightness levels (none if the backlight is turned off - e.g. VNC), and getting more frequent as additional power is added to the backlight.

    When the unit is switched to battery power, less power overall is flowing through the unit in many cases (e.g. power saving mode), as well as screen brightness automatically being reduced. Ergo, the problems lessen on battery power.

    The only way to correct this issue is to redesign and replace the backlight and digitizer systems to add more shielding between the two connections.

    ASUS does not want to admit to this DESIGN error. This error was not caught during QA testing since Asus's QA testing for "repeat designs" (i.e. ones that are speed or chipset increases in the same chassis) is very cursory. They cannot thus admit to the flaw, since it would force them to admit to a QA issue caused by lack of resources, and to take back for free repair / replacement every single R1E that was manufactured. Additionally, since it is tied to the DESIGN, and not the manufacturing of the R1E units, it is cheaper in terms of product lifecycle costs to just leave this error in place, until the line is replaced by a subsequent line or is discontinued.

    This is exactly their behavior with regards to the battery problem that occurred in the R1F (e.g. "Deny the design flaw until the new model is out that is hopefully fixed"). This policy is not going to change and any future Asus models are likely to have another issue or two that crop up that will not be found in QA and then will be ignored by operations and management.

    I highly recommend changing your buying preferences to another manufacturer. There have been good things said about the quality of Fujitsu equipment. Of course, if the Tablet form factor is not an absolute requirement, then Apple Macintosh systems are an excellent choice in terms of reliability and build quality.

    Best Regards,
    Eric

    i finally have my tablet. well , the problem seems fixed.but not at all. when the light screen is at 70% it works good and there's no problem. But when i put up the light , at 90% the problem appear again. Now i don't know if i should try to put up the light at 75-80-85% till i find a good light able to not do the corner problem , or if i should let it at 70% cuz it can be irreversible and also if i put again at 70% the problem ain't disappear. im in your hands tell me what i have to do plz tnx

    My understanding is that the poster above is correct about the design flaw. However, the ASUS tech people I spoke with explained it to me in the same way (although they didn't call it a design flaw), and then they promptly fixed it. Perhaps the customer service here in the US is better than elsewhere, I don't know.

    I've had my R1E back from ASUS in California for three months now, and so far it's been working fine. I hope it continues to do so . . .

    Yes, it works on full brightness. My pointer problem occurred only on battery power to begin with, which was really annoying for school in classes where I didn't have access to a power outlet, and even if it did, using it to take handwritten notes was more cumbersome with the power cord attached.

    Maybe you should send it to California.

    Send it in california from italy means get it in 5-6 months and i can't talk with the assistance cuz from italy i cant call em ... i should go in boston in the next months maybe if the asus assistance can fix it in a week i can do it.. but i think that will not possible.. now im writing without charger , and there's no problem .. i hope it will be in that way or i sue asus, and here in italy they have no long life if i do that

    I've noticed this problem when I'm usig the mains power. As soon as I unplug the adaptor, the mouse goes back to normal.

    Like most users, I have that right-clicking problem on the R1E. To me, this only happens when I am on battery power AND on high brightness. Most users suggest lowering the brightness to the moderate-dark level--this solves the problem about 90% of the time. However, I have found another (permanent) way to stop this annoying clicking problem without straining your eyes in the dark. I dont know if it will work for you, but it worked for me and its worth a try.

    I was looking at reasons WHY this was happening. The post made by vasbinde earlier makes perfect sense. However, I have found/discovered an easier and free solution to this problem. I'm no engineer or specialist, but I follow what is/seems logical to me.

    So, to clear things up, this is a hardware/design flaw. The right-clicking mostly happens whenever the R1E/F is in battery mode AND on high brightness. The change in source triggers the "energy saving" ("Annoying") mode, where the LCD dims dramatically. At first, I thought this problem was caused by software/driver, but its NOT--I have tried new drivers, clean installs, even installing Vista x64 (over the course of 5 months). But after reading vasbinde's post, I needed to find out what is the first thing that interacts with the hardware stuff--the BIOS .

    In the BIOS, I was searching for anything dealing with the LCD display and dimming when I found the highly suspicious page labeled:
    Power-> Power Management Settings-> LCD Power Saving: Enabled

    I was thinking that if the OS can detect and adjust the brightness on the driver level when on battery power automatically, then why does the BIOS need to do it again at the hardware-level (won't that cause conflict)? So, I took a chance and disabled that setting. After restarting, I was hoping that I would find the perfect solution. Guess what?? I did and it WORKS!!! NO MORE SPORADIC RIGHT-CLICKING :D !!! Just to be sure, I restarted my computer a couple of times, plugged and unplugged the adapter, hight and low brightness, and the problem does not appear again.

    FYI: I wrote this post on <20% battery and high brightness.

    Surprise surprise, I've got an R1E with the same freaking problem. Right clicks in the top right (or bottom left in portrait mode, it's the same corner ;) ) when it's on battery, on high brightness.

    I just went into the BIOS and turned off LCD power saving, as mentioned by the previous poster. I can still adjust the brightness, and the fault seems to have gone away. I'm on 43% battery, max brightness and it's fine. I won't get excited yet: I'll see if it's still good in a week :D

    The question begs: what functionality have I lost with so called LCD power saving off? What did this do anyway?

    It's a really frustrating problem, we can all agree. I had it happen in the middle of a thesis presentation (I was playing a video in WMP on a projector and it started clicking on the playback window: timing couldn't be worse, huh).

    Well, as I said, shouldn't get excited early.

    It's _nearly_ gone with the BIOS change. I haven't had it happen at desktop at all, but I did have it happen when I ran the Spore Creature Creator. As soon as I swapped out of the 3D accelerated game, it stopped.

    Strange. It seems like a hardware fault, but it's influenced by so many factors!
