DM4 laptop skip letter if you type fast
on November 19, 2011
If you type reasonbly fast (i.e. 45wpm or above), you want to think twice before you buy any HP DM4-xxxx series of Pavilion laptop.
I had a HP DM4-2070us and it skip letters like crazy after 3 months. Every 5-6 keystrokes you type will have one keystroke that is missed, that is, even though you did type that key, it will not appear on the screen. Or, you would hit the space bar or the Backspace key and it will not respond.
I had to call and deal with HP Technical Support. They wasted my time trying out all kinds of stuff: Windows system restore point, uninstall and re-install keyboard drivers, full system recovery (that's a fancy term for re-formatting your whole hard disc), etc., etc. All these attempts failed to fix the problem.
After struggling with all these for over two weeks, I have to ship it back to HP Warranty Repair Center and that took two weeks back and forth. During those two weeks I was out without a laptop to do my work. The Warranty Repair Center replaced the keyboard and ship it back to me. Unfortunately, that does not fix the problem. HP is kind enough to replace it with HP DM4-2180us but the whole process took another 7 days. I would be happy if that solve the probelm. Unfortunately, when I get the brand new HP DM4-2180us, it has exactly the same problem -- as soon as you type fast (over 45 wpm), the problem is obvious.
I am not the only one with this problem. Use the two links below to take you to the HP Support Forum website and you will see different people with DM4-1165DX, DM4-1127 sb, DM4-2015dx, DM4-2070us and most recently, DM4-2180us having the same problem:
