Independent warranty provider SquareTrade has released a study of more than 30,000 notebooks tracked through its extended warranty plans—and the results are a little surprising. Computer makers Asus and Toshiba led the pack in terms of notebook system reliability, with fewer than 10 percent of their systems needing repair after two years, with three-year failure rate projections of about 15.6 and 15.7 percent (respectively). And who’s in last place? Top computer maker Hewlett-Packard, with more than 15 percent of its systems failing after two years, and a three-year projection forecasting over a quarter of them will fail in three years.
