SYSTEM: 4GB RAM; 500GB DISK I have tried some of the solutions I have seen about this error and none have helped. Here is the history: 1. I have been running 12.04 LTE for about a year now with no problems. Last week I booted and got error "Checking battery state ... [OK]" upon boot. I could do ctrl-alt-f1 and get to a terminal, so i tried some remedies online (e.g. reinstalling nvidia), and none helped. I finally bit the bullet and rebuilt my system from scratch.
I was about 80% through restore and boot my system and upon boot got error "Could not write bytes: broken pipe" and could go no further unless i go to safemode (which is read-only). I tried memory check and fsck, and both came up clean. Bit bullet again and went for restore. I thought maybe my HDD was too hot, so I made sure it has better ventilation.
I was about 95% through restore and boot my system and upon boot got error "Could not write bytes: broken pipe" again. Bit bullet again and went for restore. Argghh!
In both cases I had a thumb drive with nothing but a simple text file, so I don't think that was an issue. In both cases I did a clean reinstalls. The only way I can boot now is in safe mode, or booting to install thumb drive.
If anyone knows the cause or fix, please help!
