I have been buying PCs since 1989 and I’ve never had so many problems with a PC as with the first and definitely last Lenovo I ever bought. The first thing that happened immediately was the computer kept causing my Wifi router to drop all connections every 5-10 minutes. I tried everything and finally in desperation I had to remove the Wifi card from the Lenovo motherboard and replace it with a Wifi dongle and a Bluetooth dongle. This took up 2 USB ports making it difficult to attach all my devices to the computer. Now, after less than a year, the computer won’t shut down I have to pull the power cable to make it shut off, AND it won’t start without the BIOS complaining about a fan not operating when it clearly IS operating. What a total piece of garbage. I swear NEVER Lenovo AGAIN!!!!
