Toshiba Tecra® M4-S435 14.1" Tablet - PTM40U-0F0021

The M4 performed well for the 1st year then began overheating and locking-up around 14 months old. The fan progressively blew longer, louder and at higher speed. Now it blows at high speed all the time, overheats & freezes-up. This fragments the HD & excessive heat deforms other parts all over the M4. Already had sys. board replaced in 1st year. The fan running high all the time causes the inside of the M4 to accumulate lots of dust, fan wears out quickly & battery life is diminished. Dust accumulates under the screen and looks like dead pixels. Requires dismantling the screen assembly & bezel to clean.

However, the worst issue with owning the Toshiba M4 has been Toshiba's warranty service which resulted in a quagmire where my valid warranty claim was ignored, unresolved & manipulated. After sending the M4 to Toshiba Depot for warranty repair they sent it back whereby it only worked for a couple days then overheated and fan malfunctioned. Toshiba gave me two alternatives. Either repeatedly send the notebook back-and-forth to their repair depots (which I've done & has proven futile) or call customer relations and complain. Their warranty claim process has literally used-up months of my warranty period and wasted alot of the days I could be using the notebook under warranty. Toshiba doesn't add days onto your warranty for loss of time in their depot. There are cases of notebooks under warranty held by Toshiba Depot for 4 months, "waiting for parts overseas." This results in aggravation, disservice and functional losses. I suspect my warranty will eventually expire giving Toshiba more options to ignore my claim and manipulate their obligation to honor the warranty.
