Presario CQ42 is an inexpensive entry-level laptop, those seeking a basic office workhorse-type system will find it perfectly suitable.
What was rather notable about the CQ42 was the battery performance. Cheaper laptops traditionally ship with weaker batteries to shave even more cost off the bottom line, but the CQ42’s six-cell Lithium-ion battery managed a perfectly respectable two hours and 22 minutes in our punishing full-screen, full-brightness video test with all battery-saving measures disabled. For everyday use, you could expect even more, and for a system at this price and with this size screen, that’s a nice achievement.
