You can type "system info" in search and get the hardware build list, cpu, memory. Then Google the cpu and probably get what year it dates from. CPU's have been pretty good since Intel changed from the Core series to I5 I7. The first I5's are 10+ years old now. It's probably ddr3 memory and SATA hard drive which have been good hardware. If it's from before the I5 I7 series, it's really old. Should be a dual core cpu at least.Not sure of the age on this laptop but its on its second drive.
The new AMD chips have been great laptop chips and the next gen will probably be a nice step up. If you could, waiting a year or two for the next gen AMD, plus waiting for the chip shortage to turn to surplus, buying new can be very inexpensive. Right now Intel has been behind on their process fab technology, but that just means behind AMD and TSMC, actual improvements year to year have been good.
I'm the type to keep things forever when I can, but I'm also from the generation that the first computers just did not do what you needed them to. We were usually planning the next build when the opportunity became available. I was running Neoticker on the first generation AMD single core first gigacycle cpu and the realtime data would just crush it. Neoticker dates from the 90's seems to have been not updated since about 2000. I'm always kind of surprised when it runs on new hardware.
I avoid running antivirus as just more spyware and would never go to Linkin, Facebook, but I notice the X1C gen 3 is slowing down. Not as bad as the Win 7 machines which are hurting.
