I'm just south and typing on my HP Probook similar to https://www.groupon.com/deals/gg-hp-probook-6560b-intel-core-i5-2520m-25ghz-156-hd-refurb?deal_option=1df0424a-3bd7-11e7-a5e7-002590604002&utm_source=Google&utm_medium=cpc&utm_campaign=US_DT_SEA_GGL_TIM_TTT_PADS_CBP_CHP_NBR_g*gg-hp-probook-6560b-intel-core-i5-2520m-25ghz-156-hd-refurb_productpartitionid*180954408301_campaignid*600843543_adgroupid*27871070821_prodtarget*180954408301_productid*59505339_target*pla-180954408301_d*Goods-Product-Ads_keyword*_adtype*pla_merchantdid*10018412_c*103296034981_k*_m*_adposition*1o2&mr:referralID=25eeaa9b-a0da-11e7-a158-005056941669&gclid=EAIaIQobChMIgbXvo_O81gIVD5l-Ch3O1wh-EAQYAiABEgL_3vD_BwE but with 8GB RAM.

I paid less than 300USD.

Mine came with a new spare battery so hitting 4 years should be a snap. Since you are not playing video games, this class laptop will be fine.
