Welcome to a laptop battery specialist of the IBM Laptop Battery
If there's one thing that iPads have done beyond giving travellers a better inflight entertainment option, it's the wake-up call they have given the laptop industry.
Apple may only hold 10% of the computer market, but if iPads were factored in, that share rockets to 22%. It's not a hypothetical figure, either -- it's quite clear that laptop sales from all manufacturers are dropping as sales of iPads grow.
PC makers are fighting back, both with their own tablets, and a new range of ultra-thin laptops that takes full computing power and puts it in a package that's light enough to take everywhere.
Chip giant Intel calls the category "Ultrabooks", and given that tablets like the iPad largely don't use Intel chips, it's obvious why Intel has a strong interest in Intel-based computers getting smaller and thinner.
Super-thin and light notebooks with battery like IBM ThinkPad X61 battery , IBM ThinkPad T61 battery , IBM ThinkPad X41 battery , IBM ThinkPad X40 battery , IBM ThinkPad X20 battery , IBM ThinkPad R60 Battery , IBM ThinkPad T60 Battery , IBM 40Y6797 Battery , IBM 40Y6799 Battery , IBM FRU 92P1139 Battery will be a huge benefit for business travellers though, many of whom are required to lug around a 3cm-thick, 3 kg notebook mandated by their corporate IT department.
Intel says an Ultrabook should have the following characteristics:
Instant on: the laptop must resume from sleep instantly
Storage: ultra-fast flash memory chips, not spinning mechanical hard disks
Processing grunt: no chips older than the current generation Intel Sandy Bridge Core i3/i5/i7 processors.
Connectivity: Either USB 3.0 or Thunderbolt ports. Mini-HDMI or mini-DisplayPort for video. No more chunky VGA ports -- they just won't fit!
3G: option to have 3G built in to the notebook
Battery: four to six hours battery life
Price: less than $US1,000.
The specification is a tall order against the price-tag -- notebooks with those sorts of specifications have typically fit into the "ultra premium" category, targeted at top level executives who can justify spending $4,000 on a laptop.
However, Apple has demonstrated that it's entirely possible to make a laptop that meets the requirements -- the recently updated MacBook Air jumps all but one of the hurdles, and scrapes in at US$999.
And that's a notebook that doesn't even carry the "Ultrabook" branding, as Apple never lets a lowly part supplier sully its shining aluminium branding with silly category names.
The one criterion Apple doesn't meet is the option of inbuilt 3G, due to Apple's apparent view that the most cost efficient way to get 3G to a laptop is via a tethered iPhone, not a second 3G modem with its own SIM card. Of course, it also gives Mac users a strong incentive to buy an iPhone if they're not already using one
