First please Enters a couple of times, that will help to read it. But second Its no problem just follow the instructions and it will be fine Good luck!!

I did everything correct UNTILL!!! i was just entering the command to flash, and i was thinking if the .rom file shouldn't be .bin SSSOOOO!!!...... because i wasn't safe, i rebooted the laptop to look it up. i still wasn't sure so i made a copy of the file and named it .bin for the safe side. After the .bin flash failed i gave the .rom a go and the error showed up. i went ALL the way back and started over with the guide, and result the same.... i readied the guide like 10 times and couldn't find anything what i did wrong, after looking down 10 pages i saw your post. And then it hit me.. the PRR.exe!!!!!!! Thnx svl7 for your guide !!!!

Check your battery and AC adapter with a multi-meter, the steps are described at page 21 If the valua's are correct, check on your laptop side connectors for the battery when plugged in. http://download.lenovo.com/consumer/mobiles_pub/ideapad_y400y500_hmm_1st_edition_sep_2012_english.pdf I hope this helps you a little bit.
