Blue function keys


Theres no function key lock, just the blue Fn button on the lower left corner of the keyboard.

If you cant get any of the function keys to work and the keyboard just thinks that you are pressing the standard button without pressing Fn, then this could be a fault with the contacts in the Fn key.

You might want to try

http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-4YQKLQ

To help you troubleshoot your keyboard. I think you need to get a diagnostic utility running to be sure the key is faulty.

Fn+F4


If you are using hibernation mode it causes all kinds of problems, not working, corrupting window files so you are forced to do a fresh install. The reason is windows needs to be properly shut down, other wise it will become unstable to the point you won't be able to access files. I strongly reommend to disable this function or at the very least make a backup recovery disc.

I want to know how to use the function button


The function button, or FN button, is used just like the shift key or ctrl key. Hold the FN button down and press the key with the pre programmed function you desire to use. For instance, on an HP 1245 the function or short cut key to put the computer in sleep mode is FN+F5. The Keys with functions have that feature indicated by a symbol for the function in a squared circle. Most of these are your F keys at the very top row of the keyboard. Some are on the number pad keys.

Hi, My IBM ThinkPad R51 type 1829 will not come out of hibernation/sleep mode. I have tried using all the FN and F keys, removing battery, etc. I recall this happening about a year ago and I had to...


This is called an ATX reset.
Remove the battery and the power cable.
Press and hold the power button for 30 seconds.
Put the battery back in and power cable.
Turn back on.

Computer goes in to sleep/ hibernate mode and I can not wake it up without shutting it off, and restarting


Hi,
If we are talking "hibernate", then that's what the computer does - it saves the whole memory contents on the hard disk and shuts down. You then have to power it up and it boots like always on power up, but instead of loading the system the usual way, it reads the hibernation file and restores the state in which it was when hibernated.
"Sleep" or "standby" mode is different - the system stops execution of all the running programs, switches the processor into low-speed, low-power mode, executing only the basic functions of waiting for wake-up signal. Depending on machine and settings, it will be woken up by keyboard event, system event (like laptop battery running out - time to hibernate), network activity, or the power switch.
It should wake up when the Fn key on keyboard is pressed, the lid is lfted up (if it was closed of course), or when you momentarily press the power button. If it does not, then something is wrong with your ACPI/Power Management setup, and/or there are some drivers missing or corrupt. You can try going to IBM/Lenovo website and looking for updated system drivers for your model.

I need to activate my bluetooth in my IBM r52 model,how do i do


Press Fn+F5 to open the Wireless Radio Control and turn on the Integrated Bluetooth features.
Whenever you start the computer or resume operation after it has been in standby or hibernation mode, you must turn on the Bluetooth features.
