I was experiencing issues with my R7 and I’d like to tell the community how I fixed mine just in case someone else is having the same issue (which as far as I saw online, it’s pretty common)
- When trying to turn on the machine, my Acer Aspire R7-572 won’t post (acer logo won't show up when turning on).
- Power led was on
- I was able to hear the fan
- Black screen…. Nothing appeared.
- Sometimes (one out of 7 attempts), it eventually was able to post (you can tell because of the acer logo that appears in the screen) and get into the OS (this sometimes took 30min… sometimes 6 hours or even more). The thing is that even the OS was running, the machine wasn’t performing well (applications hanging/freezing a lot… when trying to open device manager, Windows Explorer used to hang).
- There is a known issue with this machine BIOS: If you enter into your BIOS software and then you exit discarding changes, the machine won’t be able to boot. The fix is delivered in BIOS version 2.04. My machine had BIOS version 2.03. I didn’t try to get into the BIOS, so I guess this didn’t cause the problem on mine even though the symptoms were the same (Black Screen of Death). Since I was able to get into the OS, I tried to update the BIOS a couple of times; however, after restarting and waiting for it update the BIOS I eventually got the below error:
- Guarantee expired a week ago plus I am in Costa Rica, which means, I need to send the machine to US to make the guarantee effective
After trying a lot other stuff (battery reset, tried with different hard drive, etc.) I finally decided to go through the BIOS recovery mode (a.k.a CRISIS recovery) to fix my corrupted BIOS as follows:
- Prepare an USB flash drive with the required files for recovery:
- Copy the required files for the recovery procedure into your recently formatted USB flash drive. Find the files required for Acer R7-572 through this link. If you want to know how I got those files, read the “How did I get the required files?” section below. This might be helpful in case you want to do this for different ultrabook/laptop model
- Remove adapter (power cord) , mouse etc.
- Remove battery. The R7 has an internal battery which means you need to open it up (this may void your guarantee). This is easy to do, refer the first 1.5 minutes of this video to learn how to do it yourself: https://www.youtube.com/watch?v=w6PoHrQmsdk
- Attach USB flash drive that contains the files required from step 1 to the machine
- Hold down <Fn> + <Esc> keys
- Plug In the Ac Power adapter, wait about 3-5 secs
- Press the power button (at this point, you’ll hear the fan running at maximum speed. This means it is in CRISIS recovery mode)
- Now release the <Fn> + <Esc> buttons/keys.
- It may take about 2-3 minutes and the machine will power down itself....... give it some more time and it will turn on automatically. It’ll show the acer logo and get into the operating system (YAY! It’s working again!). Turn off the machine, so you can connect the battery back. From now on, it will turn on normally.
How did I get the required files?
Downloaded the latest BIOS/Firmware available from Acer for my Acer R7-572:
After extracting the files from the BIOS_Acer_2.04_A_A.zip file, I got the below files:
Note: the name of the firmware/BIOS installer (V5MM2204) derives from the mainboard name (V5MM2) + Firmware version (2.04 =>204)… this will be important later on since you need to know what's your mainboard model so you can give a proper name to the .fd file required for flasing your BIOS.
According to many posts I found online, we can extract the files from V5MM2204.exe using 7Zip utility:
Now… where is the .fd file? If I open platform.ini file, we can see the name of the .fd file: “isflash.bin”
However, it is not there… long story short, I did the following to find it:
- Used Search Everything utility to monitor the existence of the file in my HDD and entered “isflash.bin” in the search box. The list was empty (it was not present in my HDD).
- Then run V5MM2204.exe file and immediately the file existence was advertised by Search Everything tool:
- Right clicked it and selected the option “Open path”. It was saved in temp folder (%temp%\7zS46B6.tmp\isflash.bin):
Well, according to platform.ini file, we now have the correct .fd file; but, it should have an specific name and extension so it is read while the machine is in CRISIS recovery mode. According to the info found in this post, the name of the .fd file used for this particular ultrabook model (R7-572) should be V5MM2x64.fd which is derived from the mainboard model (V5MM2) plus “x64.fd”.
Hope someone else finds this helpful.
