    There is a modded BIOS available for Acer Aspire TimelineX 4820/5820 (T/TZ/TG/TGZ). The mod was done by mask89 over at Russian forum forum.ixbt.com. Here is the original post (in Russian).

    Both 4820/5820 share the SAME BIOS

    BIOS IMAGE WAS NOT TESTED. IT MIGHT BRICK YOUR COMPUTER. TRY IT AT YOUR OWN RISK!
    That being said, if BIOS flash is bad it should still be possible to recover.

    Acer Aspire 4820/5820 original BIOS v1.23 (for recovery)
    - this image can be used to recover notebook if it does not boot after flashing to the modded BIOS.

    So far, this BIOS was tested on 4820TG by Licht at forum.ixbt.com (here). He reported that it works great, except the BIOS setup sometimes freezes and computer has to be manually restarted.

    Please leave a comment on whether this works for you or not. It would also be of great benefit to the community if you posted photos of the unlocked menus.

    How to flash the BIOS: (for Insyde BIOS only)
    You need to have some kind of storage media with BIOS recovery file on it. You can use USB flash drive, SD memory card (via built-in card reader) or CD to store BIOS recovery image. For Acer 4820/5820 BIOS recovery file name must be ZQ1X64.fd. This is very important, because if file name is different then it WILL NOT WORK.. Just copy the BIOS file to an >>empty<< USB drive or SD card (FAT16/FAT32 formatted) and you have created recovery media.

    Then do the following:
    1. The notebook must be turned off.
    2. Plug in the thumbdrive into USB port or insert SD card into the card reader. They must have BIOS on them.
    3. Press & hold Fn+Esc key while powering the notebook by pressing the power button. Keep holding the Fn+Esc key.
    4. When you see laptop's LEDs flashing or notice activity on the thumbdrive's LED indicator, release Fn+Esc key.
    5. The BIOS file will be read from USB drive into notebook's memory and flashing will begin. You will NOT see any activity. Screen will remain blank. This is completely normal.
    6. Flashing process takes about 2-3minutes. Once BIOS flashing is complete, your notebook should automatically restart. Wait at least 5 to 10 minutes. Only interrupt the process if there is no response from the notebook for more than 10 minutes. If that is the case, then shutdown the notebook manually by pressing the power button. Power it on and see if the BIOS flash succeeded. If not, try the flashing process again with another USB stick and make sure you did all the steps correctly.

    If flashing did not work, then try another USB stick, make sure BIOS filename is correct and make sure all the steps are done in correct order.

    If your computer does not boot with modded BIOS
    Do not panic. It is possible to bring it back to life. Simply follow the above procedure, except this time you flash to the unmodified original BIOS image that you can download at the beginning of this post.

    Cheers!

    No, that's a hardware issue with the i3. A repaste is probably your best bet.

    Very, very cool, by the way. I'll test this when I get the laptop later this week. Is the BIOS in English, or translated to Russian?

    UPDATED: Okay, after flashing with the modded BIOS in this thread a 2nd time. I got it to install correctly. I have all the graphic settings (Integrated, Discrete, Switchable), advance options, power options, etc.

    I had to reinstall the Intel GMA HD graphic drivers when I switched to "Integrated" in BIOS. Choosing "Integrated" in BIOS stays with the Intel GMA HD graphics and doesn't automatically switch graphics in Windows 7.

    Switching back to "Switchable" in BIOS works perfectly fine too.

    The only bug I have found so far is that sometimes pressing F2 to enter "setup" will freeze the computer. Powering off the computer with the power button and restarting the computer fixes the problem. Not a major problem since nobody really messes with the BIOS that often unless a setting needs to be changed.

    THIS WAS A RISKY EXPERIMENT FOR ME. TRY AT YOUR OWN RISK! YOU COULD BRICK YOUR COMPUTER!

    Hey aylafan,
    Have you discovered any cool performance-tweaking functions in the unlocked menus? i.e. voltage control or things of that sort.

    I didn't see any voltage control settings, but there were thermal settings on how to control the fan speed by temperature in increments of 5C like 65C 70C 75C, etc. There were numerous settings like turning on/off HT, enabling multiple cores, turning on max battery mode or performance mode, etc. in the Advanced CPU Control.

    There are too many settings in the modded BIOS for me to understand at the moment. It seems like each category has a sub-category and each sub-category could expand with more settings.

    I'll have to play with this modded BIOS tomorrow. I'm going to sleep because I have early work tomorrow.

    Just wanted to mention that many of those settings do not work. Like fan, for example. It is controlled by the Embedded COntroller and not the BIOS. So changing those fan speed values will have no effect. You can try it of course. Who knows :D

    Thanks a lot for posting feedback and photos.

    With this modded BIOS, could we upgrade the lcd screens to a higher res? I thought I read on here that going to a higher res screen wasn't a simple swap, but dealt with modding the BIOS.
