I had this problem before. It is either water damage or theirs a short in your I/O port.
My solution is to leave it somewhere warm for about a day to get the water to evaporate. Take all the batteries/ faceplates/ ect off so that it doesn't stop teh water from staying in. Then after a day. Put everything back in and if it is still slow blow really hard into the I/O port and that should solve the problem.

Can I restart Lenova laptop 100s as pointer not responding


You've accidently turned off your mouse pad.

On your func & key5 or func & key8 should turn it back on.
Hold both keys at the same time.

You said your eye site is bad but the correct key will have a tiny picture of a mouse pad on it.

If func key does work try alt key! Instead! I'm doing this from memory!

Tip

Programming remote control


DIRECT CODE ENTRY

Step 1:Press and hold the device key (TV, VCR, SAT, etc) you wish to program. The illuminated ON/OFF key(*) turns on and remains on. If you release the device key at any time during theDirect Code Entryprocedure, the illuminated ON/OFF key blinks 4 times, and the process is exited.
Step 2:While holding down the device key, use the number keys (0-9) on the keypad to enter your equipment's code. While you are pressing the numbers, the illuminated ON/OFF key turns off.
Step 3:After the 4th number is entered, the illuminated ON/OFF key turns on. At this time, release the device key. If the illuminated ON/OFF key turns off, you have entered a valid code and have followed the correct procedure. If you enter a code that is not in the Code Lists or you do not follow all of the correct steps for Direct Code Entry, the illuminated ON/OFF key blinks 4 times when the component key is released - an indication that a programming error has occurred. In that case, repeat the process from Step 1 and try the next code in the list.
Step 4:To confirm that remote is programmed with the correct code for maximum functionality, test it. If some of the features of your equipment do not work, try programming the remote with a different code in the list until you find the code that allows the remote to control the majority of your component's functions as different codes can provide different levels of functionality.
* some models like the RCR450 have a LED indicator light in place of the illuminated ON/OFF key.

AUTO CODE ENTRY

If your component's brand is not listed in the code tables, or if you have tried all of the codes for your brand and the remote does not operate your component, try the Auto Code Search method below. The remote will cycle through all of the codes, in the event that your code is listed under another brand. TheAuto Code Searchmethod may take a long time because the remote searches through all of the codes in its memory for the code that operates your component. Therefore, if your brand appears in the CODE LIST You should try first theDirect Code Entrymethod described above.
Step 1:Manually turn on the device you want the remote to control (TV, VCR, DVD, cable box, etc.).
Step 2:Press and hold the device button (TV, VCR, DVD, etc.) you wish to program. The illuminated ON/OFF key turns on and remains on.
Step 3:While holding the component button down, press and hold the ON/OFF key. The illuminated ON/OFF key turns off.
Step 4:After holding down both keys for 3 seconds, the illuminated ON/OFF key turns back on.
Step 5:Release both keys. The illuminated ON/OFF key remains on.
Step 6:Press and release the PLAY button, then wait 5 seconds to see if your component turns off. If your component does not respond, continue to press the PLAY key every 5 seconds until your component turns off. Each time you press the PLAY key, the illuminated ON/OFF key blinks and a block of ten codes are sent to your component. This process continues until all of the codes have been searched. If your device has not turned off after all codes have been searched, the illuminated ON/OFF key blinks 4 times and turns off. The Auto Code Search Entry method is exited.
Step 7:When your equipment turns off, you know'll that the correct code is in the last block of 10 codes sent. Press and release the REVERSE key, Wait 2 seconds to see if your component turns on again. If your component does not respond, continue to press the REVERSE button every 2 seconds until your component turns on again. This will isolate the correct code in the last block of codes sent. Each time the REVERSE key is pressed, the illuminated ON/OFF key blinks.
Note:If you accidentally press the REVERSE button after your device responds, press and release the FORWARD key. Wait 2 seconds to see if your component turns off again.
Step 8:Once your component turns on, you have found the correct code. You must save the new code by pressing and releasing the STOP key. The illuminated ON/OFF key turns off.
Important:You must press the STOP key to save the code or the correct code will not be stored!

MANUAL CODE SEARCH

Step 1:Manually turn on the component you want the remote to control and keep the remote pointed at it.
Step 2:Press and hold the component key (TV, VCR, DVD, etc.) you wish to program. The LED indicator light turns on and remains on.
Step 3:While holding the component key down, press and hold the ON/OFF key. The LED indicator light turns off.
Step 4:After holding down both keys for 3 seconds, the LED indicator light turns back on.
Step 5:Release both keys. The LED indicator light remains on.
Step 6:Press and release the ON/OFF key repeatedly until your component turns off. Each time you press the ON/OFF key, the LED indicator light blinks, and the next code in the list is sent. This process continues until all of the codes in the Code Lists have been searched. If your component turns off, you have found the correct code.
Because there are so many codes, you may have to press the ON/OFF key many times - possibly up to 200 times.
Step 7:Once you have found the correct code, you must save the new code by pressing and releasing the STOP key.

CODE RETRIEVAL

If you used one of the Code Search methods above to program your remote you may want to record the codes for future reference. Retrieving the actual code and writing it down will save you time if you ever need to program the remote again (when you change the batteries for example). If the codes are recorded, you can use the Direct Entry method to reprogram your remote to control your device, which is quick and easy.
Step 1:Press and hold the component key (TV, DVD, etc.) whose code you wish to retrieve. The illuminated ON/OFF key turns on.
Step 2:While holding the device key down, press and hold the INFO key. The illuminated ON/OFF key will turn off.
Step 3:After holding down both keys for 3 seconds, the illuminated ON/OFF key turns back on.
Step 4:Release both keys. The illuminated ON/OFF key remains lit.
Step 5:Starting with the number 1 key, press and release each number key on the keypad in the following order: 1 to 9, then 0. The number that causes the illuminated ON/OFF key to blink is the first number of the code.
Note:
TV codes begin with the number 1
VCR codes begin with the number 2
DVD codes begin with the number 3
Satellite receivers and cable boxes, codes begin with the number 5.
Step 6:Repeat step 5 until you have retrieved all 4 numbers in the code.
Step 7:After the fourth number is retrieved, the illuminated ON/OFF key blinks briefly, then turns off.
Note:To exit theCode RetrievalMode, press and release the "GO BACK" button at any time.

Alarm activated and is unable to deactivate


REMOTE KEY INITIALIZATION For this type of key.

The initialisation of the FZV keys is required to establish the Lock/Unlock signal synchronisation with the GM V. The initialization procedure provides the GM with a key identification number and a "rolling code" for each key. If the initialisation is not performed, the GM will not respond to the key signals. Up to 4 remote keys can be initialised. They must be initialised at the same time. Key initialisation is only possible with the vehicle unlocked.

Procedure:
1. Close all doors and have all keys available.
2. Using key number 1, turn the ignition switch to KL R, then switch off within 5 seconds and remove the first key.
3. Within 30 seconds of turning the ignition switch to "off" Press and hold button #2 .
4. While holding button #2 , press and release ("tap") button #1 three times within 10 seconds.
5. Release both buttons. The LED in the key will flash momentarily. The GM will immediately lock and unlock the doors signalling a successful initialisation.
6. If additional keys need to be initialised repeat steps 3 - 5 within 30 seconds.
7. Switching the ignition to KL R completes the initialisation.

SERVICE NOTE:
The key memory function of the GM responds to the key identification number of each key. If the keys are not initialised in the same order prior to initialisation, the key memory functions activated by the keys will not be assigned correctly. Always initialise the keys in the same order.

Found some quick solutions including the manual for you

first here is the link for hte code list and manual http://www.rcaaudiovideo.com/remotes/2-3-devices/?sku=RCRN03BR
which i got from various sites after researching your problem for about 30 minutes please let me know if this works i hope i helped i tried really hard

if that doesnt work try these methods PLEASE LET ME KNOW IF I HELPED

for this first method you need the direct code which is 04
  1. Manually turn on the component you want the remote to control.
  2. Locate the Brand Codes in the Code Lists.
  3. Press and hold the component key you wish to program. The illuminated ON·OFF key turns on and remains on.
  4. While holding the component key down, press and hold the ON·OFF key. The illuminated ON·OFF key turns off.
  5. After holding both keys down for three seconds, the illuminated ON·OFF key turns back on.
  6. Release both keys. The illuminated ON·OFF key remains on.
  7. Refer to the Brand Codes. Press and release the appropriate brand code key (Numbers 0-9), using the number keys. The illuminated ON·OFF key blinks once.
    • Note: If you do not press a valid Brand Code Search key, the illuminated ON·OFF key blinks four times and turns off. The last programmed code under that component key is retained.
  8. Press and release the ON·OFF key repeatedly until your component turns off. Each time you press the ON·OFF key, the illuminated ON·OFF key blinks, and the next code is sent. The Brand Code Search begins with the first code in the chosen brand list for that component and cycles through all the codes for that brand. If your component turns off, you have found the correct code. (If it cycles through and the illuminated ON·OFF key blinks four times and turns off, all codes in the chosen brand list have been searched and another programming method should be tried. The Brand Code Search mode is exited.)
  9. Once you have found the correct code, save that code by pressing and releasing the STOP key. The illuminated ON·OFF key turns off. You must press the STOP key to save the code or the correct code will not be stored!
  10. To confirm that the component key is programmed with the correct code for maximum functionality, test the component. Attempt to control a variety of the component's functions with the remote. If some of the features of your component do not work, program the remote with a different programming method.
if not try this for auto code search

  4. After holding down both keys for three seconds, the illuminated ON·OFF key turns back on.
  5. Release both keys. The illuminated ON·OFF key remains on.
  6. Note: If you press an invalid key during Auto Code Search, the illuminated ON·OFF key blinks four times and turns off. The last programmed code under that component key is retained.
  7. Press and release the PLAY key, then wait five seconds to see if your component turns off. If your component does not respond, continue to press the PLAY key every five seconds until your component turns off. Each time you press the PLAY key, the illuminated ON·OFF key blinks ten times and a block

My ti-84 plus it does not respond to the function + or - OR other function, & it come up to display very slow ,slow. thanks


Hi xvbanh,

You need to free up some memory. Try clearing your RAM. Your calculator should operate properly afterward.

Go to [2nd] [MEM] [7] [1] [2]

If your calculator still won't let you delete the RAM memory try the procedure below.

Remove one of the AAA batteries. Press and hold the [CLEAR] key. While holding [CLEAR],
reinsert the AAA battery and then turn the calculator on. The calculator should display the
message "RAM Cleared". Release the [CLEAR] key and then press it one more time to remove the message.

There are a number of reasons that may causing a Mac computer running slow, but generally two factors: hardware part & system part. For hardware part: I guess it's OK if your Mac is not that old. For system part: there might be a lot of junk files, caches, registry errors... about 80% slow Mac caused by this reason, if so, try cleaning the system.

I have a jbl spyro and the left speaker will just not work at all. I've checked the connection and it's pushed in as far as it will go!


1. Go to "Adjust Audio Properties". In Windows XP, you can get here by right clicking on speaker icon in system try.
2. Click on speaker volume push button.
3. Increase the left volume to maximum.
4. Now, play some music or some audio content.
5. Then reset L and R speakers default (L and R speakers will be at 50%).
6. Now, both speakers will work fine.

FDD2 used to balancing sound between two speakers was probably malfunctioning and it was reset by above exercise.
