I have a pair of Satelit p25 toshiba top end computers now about 4 years old cost 2800.00 USD each new from Best Buy.
My wifes has failed but she never ever did anything but use and abuse it.
I take good care of mine, cleaning out the junk everyweek, do a disk clean, registry clean using JV16 tool and then a defrag. After all that is done, I do a back up to an external hard drive through usb.
Mine is just like new. Both have always run a really hot power supply. It is hot enought that I don't touch it when it is on and keep it on an insulator on the table. The fan runs most of the time once it is warmed up, unless it is hibernating. Both these computers have 17 inch screens if that makes any difference. The batteries lasted about 2 years and were replaced but not used a lot except on motorhome trips.
these have not been coddled but used a lot. The failure on my wifes toshiba is the cable between the mother board and the monitor screen. I guess two many times of opening and closing it. The cost to repair was such that I bought her a new Laptop because the value of the toshiba was less then the repair cost.
