[Serial Number Acer Iconia Tablet
Luther Lazaro
After months of googling and making a mess in /sys, I still have not got the device working. I was working under the assumption that the device hangs off the i2c bus, but a "lucky google" today uncovered that it is showing up through acpi - acpid is present in my daemons array of rc.conf and the kernel module acer_wmi is also loaded.
Solved. I now have a working accelerometer. The acer-wmi kernel module needs to be patched to recognise and configure the device. I am now running a custom kernel with this patch and it is working brilliantly.
[EDIT] Being a laptop, I am guessing the accelerometer is possibly on the hard drive?? used for shock protection?? So if that is the case, I am not sure you will be able to utilise it in the same way as a tablet's accelerometer. There are articles on the web for setting up hard drive accelerometers in linux. The other consideration you need is that the accelerometer may not be on acpi. It could be on the i2c bus (commonly where sensors such as fan speed, core temps etc are located), in which case you will need the i2c driver to get the accelerometer events recognised in the kernel (ensure i2c kernel modules are loaded). So check exactly how the kernel detects the accelerometer, is it on acpi or the i2c bus?[/EDIT]
Acer customer service tells me that the on off switch is an integral part of the mother board and I need to replace the mother board at a cost of over $200. Is there a way to fix the switch or should I just trash it. My internet research indicates that this is a known problem with this unit but I have not yet found a solution.
Dennis, my Acer Iconia has the same problem, the on/off switch is stuck inside the tablet and unable to reset it. I would like to know where you had yours serviced so I may get mine worked on..thank you in advance for your help.
Mine was done by a local tech at a repair shop in Las Vegas. I had to try several repair shops before I could find someone who was willing to try. I had a very good idea what was wrong and had taken the back off before I went to this shop. After he took a look at it he was willing to try. You might have some luck with the same approach. I doubt that my shop does mail order work but if you can't find someone locally let me know and I will ask if they are willing.
I finally got this fixed this week. From my internet research I found that the problem is a design flaw with the on off switch. The button you push is not a switch, it pushes a lever shaped like a tiny golf club. The "club Face" contacts the actual switch. Apparently it is possible to push too hard and dislodge the contact. The repair involved removing the back, taking out the mother board to access the switch, positioning the contact properly and reinforcing it so this won't happen again. It was more than I wanted to try so I managed to find someone to do it for me, he charged $49.00 and it now works perfectly.
My power button broke on my Acer, well, the 3 very small prongs that connected the power button to the mother board broke. So I after a few attempts to think of ways to fix it back on there, I decided to take the power button off completely, and just use a piece of folded up aluminum foil to touch the contacts!! It works like a charm for me! :)
I just fixed this today, unfortunately it required soldering wires to the MOBO and out a little hole I made. The wires can either be touched together to act as a button, or they can be soldered to a little button and used as an external button. There might be a way to connect the button on the inside of the unit but I was unsuccessful in doing this.
I assume you want a picture of the wires soldered on the MOBO. I should have made a guide about this, but I didnt. Now I really would rather not open it up again. Its actually easy (at least to me) to get the MOBO out and see where the original power button was. It only has 3 solder pads that connect the old button to the board. What I did was solder a wire to each of the left pads, leaving the third one alone. This is while looking at the MOBO while the power button is on the top right.
The only guy who really knows how to fix the power button issue professionally he even put a hard plastic protection around the power button that acer never did so no matter how light or heavy you push the power it will last for a long time not to mention affordable quick turnaround fast reliable repair service online specially OFFLINE!!! also comes with 30 days warranty that you will never gonna need it!. nobody offer this type of service in CA and nationwide only this guy -Iconia-A500...
I agree with Sarah Carter. I removed the button, stuck a piece of aluminum foil in there to make the connection, and it started up like a charm. It may not look pretty, but at least it's functional now. (And it only cost me pennies for the tiny strip of foil that I used.)
A shop near me did it for me. cost me a tenner but then I put hot glue over it and let it set solid so it won't come off again it was a small phone/ computer repair shop in Hull UK I would have done it myself but my soldering iron is like a spade compared to what was needed for this job as the button is really small and has three connections on it
The Acer Iconia A500 is a tablet computer designed, developed and marketed by Acer Inc. The A500 launched with the Android Honeycomb operating system which is now upgradable to Ice Cream Sandwich 4.0.3 (since April 2012). The tablet is also sold in almost identical form as the Packard Bell Liberty Tab G100.[5]
This tablet has a 5 MP and a 2 MP front camera for video calling. It is powered by 1 GHz Nvidia Tegra 250 processor and 1024 MB DDR2 RAM. The A500 is sold with 64GB flash in certain countries although both 16GB and 32GB models are available.[6]
The A500 was one of the first Android tablets to feature a full size USB port directly in the tablet, opposed to the ASUS Eee Pad Transformer that provides only one with the accessory keyboard dock. Since the latest version of Android Honeycomb (3.2) The device supports a much larger variety of USB devices including NTFS and linux partitions. Previously, the number of compatible devices was very limited, with only USB mice, keyboard and FAT32 formatted drives (NTFS and other file-systems were available through apps that depend upon rooting) being able to be used with the tablet.
The tablet was offered with Android 3.0 upon release. Android 3.1 and 3.2 was made available later through over the air updates and Android 4.0.3 (Ice Cream Sandwich) update has since been made available (April 2012).
Root was possible using an app developed by sc2k and published at xda-developers.[7] up to Android version 3.1 after which the vulnerability used was patched up by Acer, although by downgrading to one of these susceptible version of Android one can install ClockworkMod Recovery before installing a pre-rooted version of 3.2.1[8] or indeed Ice Cream Sandwich.
As of now, there are a few ROMs that are built based on the leaks and many of them were updated numerous times to be based on the newer releases as they came through from Acer.[10] Many of these, such as the popular 'Flexreaper' ROM are now based on actual OTA releases.[11]
Developers on the TegraOwners forum have produced community maintained and developed builds of later Android releases, which have not been approved nor endorsed by Acer. These releases include builds based on:
Ubuntu Linux also was made to work in the Acer Iconia A500 by installing the kernel in place of the recovery image.[25] The root file-system for the Ubuntu installation must be placed in a SD card. Other sources[26][27] also state that it is possible to run Ubuntu 10.10 by using chroot and VNC for a Linux GUI.
In 2019, Android 10 Go was released. Some YouTubers post videos about how to dual boot a tablet like the Acer Iconia A500. They stated that Android Go is really lightweight and free up a significant amount of space for installing Windows 10.
I decided it was finally time to work, fired up adb and launched eclipse to test an app and I discovered it wasn't in my devices list. I've tried installing the acer drivers. It puts a folder in my Program Files directory...but I don't see what I'm supposed to do there. There's "EUUDriverInstaller" but when I click on it nothing (seems to) happens.
I've reboot several times on both device and laptop.I've uninstalled / reinstalled the application that made that driver directory.I opened an application in the driver directory under the x64 folder and it opened up the windows driver installer and installed some drivers...but still no composite adb when I plug it in.It is on usb debugging and I've toggled it on and off.
A500 using 3.2 roms (I have other 4.x devices, so I'm saving this one). Using Windows 8. Downloaded and installed the Acer 1.06 drivers. Have previously isntalled Google ADB drivers for the Nexus 7 from android-sdk\extras\google\usb_driver\amd64 (or i386 if that's appropriate), but that may not be required.
Plug in the A500, and launch device manager. The Acer Iconia Tab A500 device shows up in "Other Devices" folder but with no drivers installed. Click on the device, click on "Update Driver". Select "Browse my Computer". Click "Let me pick from a list of device drivers on my computer". From that list, select "Android Device". Select "Google" as manufacturer, and select "Android ADB Interface" as the Model. CLick "next". Click "Yes really, really do it please". Done.
On windows 8.1, the behavior is different again. The device will show up in the "Android Device" folder. Right click on that, and proceed as described above to select and isntall the "Android ADB Interface" driver. I'm having to do this with all my devices. Windows 8.1 seems to istall everything BUT the ADB driver, which you need to forcibly install using this procedure.
Folks here are right: Win 7 is single-minded about using its own driver for this tablet, and the Acer installer simply drops the files onto the drive. In fact, it drops them onto the drive, then seeing that the Windows driver is already in place, happily deletes the Win7 drivers it has copied out of the installer. I spent an hour in Device Manager trying to con Win7 into using the Acer drivers, but it kept telling me they were not compatible.
