I had to clean and re-do the adhesive tape of Acer Aspire 8951G screen as bugs/insects were leaving inside the screen and the plastic on top of the screen stop sticking to the frame. I also had to replace the battery where I had to remove the bottom case and keyboard. When testing the battery, make sure to lock the battery switch (orange) located underneath the case, or else you will see "No battery detected" on Windows, even though your battery has been plugged in to the board.

I got an error Task image is corrupt or has been tampered with 0x80041321 when saving a Windows Backup task on Windows 7.

This happened after a revert to Windows 7 after it got updated to Windows 10. Solution that worked for me, may not work for you though was:

1. Backup everything and delete all files inside C:\Windows\System32\Tasks\Microsoft\Windows\WindowsBackup.


2. Go to registry and export the keys inside to back it up HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Schedule\TaskCache\Tree\Microsoft\Windows\WindowsBackup then delete all keys such as:

  • AutomaticBackup
  • Windows Backup Monitor

3. Then create your Windows Backup again.

I updated a friend's Mac A1342 from Lion v10.6.8 to El Capitan then to Sierra v10.12.3. You can't update 10.6.8 to Sierra direct as minimum requirement is version 10.7.

Mac was a bit slow after the update as photoanalysisd and other daemons are running in the background. I also decided to upgrade the RAM from 2 x 1GB to 2 x 2GB, so I shut it down, when I switched it back on that is the time the progress/loading bar is stuck to 100%.
