[Trisquel-users] Thinkpad T420s 5 beeps

[jcmartinez2129]

Hello guys, recently I bought a thinkpad t420s from ebay, this is a  
refurbished computer, when I turned it on, it started correctly and could  
access to the windows installation that came with it. After a reboot to  
install GNU/Linux the unit didn't boot up, I could hear 5 beeps coming from  
the computer when I tried to reboot again. The current state of the computer  
is that every once in a while it will boot but most of the times it won't.  
Does anyone have a suggestion? I contacted the seller on ebay but for now  
it's unresponsive. Thanks for any help you can provide
