How many problems in older laptops are caused by bad capacitors?Quite easy to spot when you open them up and fairly easy to replace (and cheap)as long as you have a soldering iron.Plenty of you tube videos to explain this problem.
Scored a great samsung monitor this way.The thing was in standby all the time.Opened it up fairly simple.Sure enough one bad capicitor.Now it works great.
I have a toshiba it works ok.Just needs a new battery.Had a problem with one of the buttons after a couple of months which came loose. Toshiba told me to take it to a local repair shop who fixed it under the warranty.
