Which model do you recommend.
there are so many different ones.
Lenovo W530 Thinkpad Laptop
Thinkpad used to be the Corporate standard.
I made a list once of all their model number breakdowns, then chose that model.
It has been very reliable for a few years now.
Has Windows 10.
Replacement batteries 5.2 Ah and extra longer 8.4 Ah.
DVD plus peripheral ports standard eg USB 2 & one 3, hdmi, ethernet wired, bluetooth wireless, etc
3 types cursor input: mouse, finger stick & square area finger slide. All 3 get used at different times.
The flexibility of input is nice.
Bluetooth mouse saves a USB port, but there are many ports. Mine has 4 which I never use all. One is always powered on.
Just be sure power is off when swapping batteries.
All other laptops MUST be near an outlet, or the battery runs down.
The idea with laptop batteries was made by manufacturers, a few years ago, is people rarely run the computer long enough, so only Thinkpad still makes removable swappable batteries, which I still like the option of power cable free.
Locking cable is nice if you go to bathroom, laptop can be locked to table stand temporarily.
Preload only OS, not antivirus. Buy separately, though I do not use it.
