If its an Acer aspire and over 2 years old you on borrowed time anyway.
My Aspire One is getting on for six years old, having been acquired in mid-2008. It's still going, currently running Mint 13, although I've upgraded to to 1.5GB RAM (max), added an internal Bluetooth adapter and replaced the SSD with a faster 32GB unit. I'll be really sad when it finally expires, it's done sterling service.
