1. The F's keys (F1, F2 and so on) are not set up as you're used to. Meaning that in order to get the F4 functionality you will need to click on the FN button+F4 instead on the other way around (just F4). This can be resolved in the BIOS setting, but very weird that it works like this.
2. The CAPS LOCK's light indicator isn't placed on the keyboard it self, but rather on the bottom of the computer which makes it almost impossible to see if you're a big Caps Locks fan or just want to know if it's on or off.
Beside that, the laptop is very powerful, and I didn't experience any wireless problems so far (bought this laptop almost two weeks ago)."
"I can't say anything good about this computer. Audio and video never seemed to work properly despite the fact that I spent many hours with Lenovo's tech support people on the phone. I am returning it right now."
"The G510 has performed very well with various applications. The screen is excellent. Battery life is better than average. The built-in Backup feature is great. The main complaint about this model is that there is no indicator light to show that Num Lock is ON or not. There is a light to show the status of Caps Lock, but the only way to find out if Num Lock is ON is to try to type a number on the number pad. After booting, Num Lock defaults to OFF (not that you can tell, though, until you try to use the number pad.) I haven't figured out how to get to the BIOS when booting up with Win 8.1 to see if there is an option to set Num Lock to ON as the default. Minor detail, but frustrating. Why have a number pad with Num Lock OFF as the default? And why no indicator? The right-hand Shift key is smaller than on most keyboards, but overall, the feel of the keyboard is excellent. Rather than on-line manuals, it would be nice to have a printed User Manual specific to the model purchased."
"The Elan touchpad and drivers are substandard. The touchpad is jumpy and periodically does not respond. This one problem, that Lenovo will not correct, makes these laptops almost completely unusable."
