Welcome to a Laptop Ac Adapter specialist of the Hp Ac Adapter
Typing on the Taichi 21 can feel a little cramped compared to typing on a 13.3in Ultrabook, for example, but it does have a good keyboard and we got used to the units size after a short while. The keys feel solid, they have good travel, and they are backlit. The touchpad is 105x63mm, which is huge considering the size of the laptop, and it feels very smooth. It supports swipe-in gestures for Windows 8 and it was quite sensitive during our tests — if often registered unintended taps and double-taps. The ASUS Smart Gesture software that controls the touchpad isn't great, with very limited scope for adjusting its settings. We also couldn't get the three-finger sideswipe gesture to work properly, even though it was enabled in the driver.
There are some omissions when it comes to built-in connectivity. You don't get an Ethernet port in the chassis, for example, but an external USB dongle for this is provided. There is also a dongle for a VGA port, which plugs in to the unit's mini-VGA port with batter such as HP 0950-3988 Ac Adapter, HP 177626-001 Ac Adapter, HP ACC10H Ac Adapter, HP Pavilion ZT4000 Ac Adapter, HP DC359A Ac Adapter, HP Pavilion ZE2200 Ac Adapter, HP PPP012H Ac Adapter, HP Omnibook 2100 Ac Adapter, HP OmniBook 2120 Ac Adapter, HP Omnibook 3000 Ac Adapter, HP Omnibook 4100 Ac Adapter, HP Pavilion ZE2000 Ac Adapter. Two USB 3.0 ports are present, one on either side of the chassis, there is a combination headphone/microphone port, and you also get a micro-HDMI port (you'll need to buy an adapter or a micro-to-full-sized HDMI cable to use it). There isn't a built-in SD card slot unfortunately, so you'll have to use a USB-based SD card reader if reading photos off an SD card is a requirement for you.
There are dedicated tablet buttons along the left side of the chassis, which include volume and the aforementioned toggle for the second screen. This toggle is handy if you want to make sure that the second screen is locked and won't switch on when you close the lid of the laptop. The right side has the power switch and we like the fact that it is placed separately to the other buttons on the chassis. On models such as the Toshiba Satellite U920T, for example, the power, volume and auto-rotate buttons are all in a line, which means there is a chance of pressing the power button by mistake.
Stereo speakers are built in to the ASUS' chassis, their grille slits visible on either side, and they actually provide decent sound for such a small laptop. You'll still need to plug in a pair of headphones if you want a loud listening experience, but for YouTube videos and casual music playback while you work, they are fine.
Wireless networking is handled by a dual-band Intel Centrino Advanced-N 6235 adapter, and you also get Bluetooth and two cameras (in-facing and out-facing).
On the inside, the Taichi 21 features an Intel Core i5-3317U CPU, 4GB of DDR3 SDRAM and a 128GB solid state drive. It boots up in about 10sec (the time it typically takes to get to the login screen) and system resume time from sleep is about 3sec (with the ASUS Instant On software enabled). The overall performance of this configuration is on par with other systems we have seen that use the same CPU as well. In the Blender 3D rendering test it recorded 19sec, while in the iTunes MP3 encoding test it recorded 1min 8sec. A 3DMark06 score of 4446 shows that this laptop isn't ideal for running taxing 3D shooters, for example, but it will do just fine when running games such as Riptide GP from the Microsoft store.
