My toshiba s\atelite a135-s4527 wont turn on and

Could be the "resume" battery that has died - its an internal battery shrink wrapped in bright green plastic on tosh's normally - you might be able to get to it by unplugging stuff, battery, cd rom etc etc....unplug it and plug it back in again, if it comes alive again order another. I went on a toshiba laptop maintenance course years ago with a company that i worked for and that error that youre seeing was the fix....see if that works...
