What should I do about my Lenovo computer? My warrenty has expired, do I have to renew? Despart?

Lenovo told me my computer will crash?

Thinking your laptop will crash without insurance is like thinking your car will crash if you do not have car insurance. If you want to extend your warranty then do it but be sure you know what the warranty covers and how much it will cost. You may decide the price is not worth the coverage.

No Lenovo agent or representative will ever, ever, tell you your system will crash without warranty.
Whoever told you that is a a scammer or crook, or just dishonest. Take your business elsewhere…
