Have your machines serial number id (SNID) ready. If the machine is still within the warranty period, go to this link below and arrange for a warranty repair ASAP. Responses made using the middle row of keys were faster and more accurate than responses using the top and bottom row of keys. >Nevermind, resetted according to the video above, even not using WiFi, the BIOS still shows V1.08 and the keypad numbers not working > This suggests a hardware problem. Critically, participants' response times showed an interaction of stimulus format and keypad layout: participants were specifically slowed when entering numeric stimuli using a telephone keypad layout. If any key matches with the alternate numbers, then press it along with the. In addition, the results showed that participants were more accurate when entering stimuli using the calculator keypad layout. To activate the Numpad, look for the Number lock key (like Numlock, Num, or NumLk). The results indicated that participants' memory of the layout for the arrangement of keys on a telephone was significantly better than the layout of a calculator.
Stimuli were presented in either a numerical or phone format. Fifty-seven participants saw a 10-digit numeric stimulus to type with a computer number keypad as quickly and as accurately as possible. The purpose of this study was to determine if entering different types of numeric information was quicker and more accurate with the telephone or the calculator layout on a computer keyboard numeric keypad. Two commonly used keypad arrangements are the telephone and calculator layouts.
