Welcome to a Laptop Battery specialist of the Asus Laptop Battery
The ThinkPad X1 Carbon got just four hours, one minute in this test, which means that in more normal use, you’d likely get about five hours. That is well below the company’s claim of 6.3 hours.
H-P’s Envy 6 Sleekbook, available now, is an entirely different type of laptop. It costs less than half as much, but is a lot larger. It has a 15.6 inch screen, though with a lower resolution of 1366 by 768, so it actually displays less of a Web page or document without scrolling.
H-P calls this laptop a Sleekbook, not an ultrabook, because it uses an AMD processor, and ultrabook is a term that applies to Intel-based laptops. The Envy 6 Sleekbook is almost 15 inches long and 10 inches deep and just under 0.8 inch thick. It weighs 4.5 pounds. It isn’t hard to carry, but if you’re used to a smaller, lighter laptop, there’s no mistaking the fact you’re lugging something bigger. The design makes the machine look lighter, with a black, brushed aluminum cover and a red, rubbery bottom.
In general, I found the Sleekbook with battery like Asus A32-W7 Battery , Asus A32-X51 Battery , Asus A33-M9 Battery , Asus A33-W7 Battery , Asus A41-W3 Battery , Asus A42-A3 Battery , Asus A42-A4 Battery , Asus A42-L5 Battery , Asus A42-M6 Battery , Asus A42-U5F Battery , Asus A42-V1 Battery , Asus A42-V6 Battery to be a bit sluggish, though it handled every program properly. The touch pad also felt stiff, though the keyboard was fine. The desktop is marred by icons for trial software, especially games.
But the Sleekbook has some advantages beyond price. It boasts a 500 gigabyte hard disk, an HDMI port for connecting to a TV, and an Ethernet port for wired Internet connections—ports that the costlier Lenovo lacks.
The H-P also outperformed the Lenovo on my battery test, clocking in at four hours, 40 minutes, which means you might get six hours in normal use. The company claims up to nine hours.
The X1 Carbon continues the tradition of the ThinkPad’s superior design and performance, and is a solid choice for those who can live with its price tag and middling battery life. The Envy 6 Sleekbook is a good choice for students, provided they want a heavier, larger laptop.
