Hi,
Please try following DIY
1.Please remove the battery and then press the power button for a minute without connecting the adaptor then refix the battery and check whether it is working.
2.Check after removing the battery with adaptor only.
3.If then also it is not working check whether the num lock is responding if yes then this is a RAM refixing or changing issue otherwise a motherboard issue if the adaptor is working fine.

How do I set coffee maker to shut off in 2 hrs and how to use clean cycle


Not knowing which model you have, here are the instructions for my model. Perhaps yours is the same.

"The Automatic Shutoff
Time can be programmed anywhere from immediate shutoff after completion of the brew cycle up to four hours. When the coffeemaker shuts itself off, two tones will sound. Two hours is the default time. The 0:00 setting shuts the unit off immediately after brewing is complete.
To check the current setting, press and hold the On/Off button and the Automatic Shutoff Time will be displayed.
To change the preset time, press and hold the On/Off button until the red power light and LCD display begin to flash. This signals that you have entered the Set Automatic Shutoff mode.
Press the Hours and Min buttons to scroll forward through the digits until desired time appears. The first setting which appears is preset at 2:00. When it's at 4:00, the next press key of Hour will roll back to 0:00, since four hours is the maximum Automatic Shutoff setting. Pressing and holding either button will allow you to scroll continuously, slowly at first, and then to accelerate to the rate of about three digits per second. As the desired time setting approaches, release the button and then press repeatedly to advance one digit at a time. The Automatic Shutoff Time (ASO) may be 8 9 programmed either before or during coffee brewing. You may also re-program the ASO time when brewing has been completed. If you do so, the Grind & Brew™ will automatically account for any time that has already elapsed after brewing. For example, if you set the ASO for 40 minutes and 25 minutes have already elapsed, the Grind & Brew™ will shut off automatically after 15 minutes (40 minutes minus the 25 elapsed equals 15 minutes)."

Mine doesn't have a specific clean cycle, but to decalcify the unit, add 1/2 vinegar to 2/3 water in a full cafree and run it through. If it's really calcified, turn off about 1/2 way through and let it set for an hour. Then turn it on and finish, Remember to run a pot of clean water through the wash out the vinegar taste.

Acer Aspire 5733 Series won't start


For this kind of issue, please follow up the following steps to check:

1.confirm the battery and ac adapter connect the laptop normally.Maybe the bad connect lead to this problem. If there are no lights when you turn on laptop, one of possible reason is that your adapter is malfunction.

2.the second possible cause is laptop dc jack failure. If the dc jack is broken or loose, you are required to replace it or repair it.

3.Another possible reason is that there is something wrong with laptop motherboard. For this situation, it includs two kinds of possibility,a failure in an electronic circuit and BGA malfunction.

For more detailed reasons and solutions, please have a look at the following article:http://www.ifitjams.com/lappower.htm

If you verify your laptop adapter is dead and you plan to order a new one, I recommend one for you on the basis of your laptop model:

It shut down automatically and won't turn on after that.


The computer/laptop is heated up too much on the same place. You have to wait about 5-10 minutes if it automatically closes, so it it gets cold.

Laptop just keeps shutting down and won't turn on


it may be one of the causes, but the main reason for it is the power supply keeps on fluctuating. You may call Acer for a possible replacement for it..

My acer aspire 6920g will shut down automaticly when i want to log in to my system, after the boot menu the cooler is turning off for 1 second.


When the CPU overheats then it will shut down (i.e. thermaloverload) and won't boot up again until it has cooled down. If this is theproblem is not fixed then the CPU will eventually fail.
A faulty fan causes the problem or the fan and heat sink assembly are cloggedwith dust.
Check the CPU fan to see if it spins freely, if not replace the fan.
If the fan and heat sink is clogged with dust the remove the dust and make surethe vents are clear and dust free. Use a can of compressed air to do this.

No instructions on programming auto shut-off time (feature listed on box).


You have to use the "Auto-Off" feature, which is located on the same button as on/off:
The automatic shutoff time (ASO) can be
programmed to shut off immediately after
brewing (0:00) or up to 4 hours later. The
default shutoff time is 2 hours.
Press and hold the On/Off button to display
current shutoff time. To change the preset
time, press and hold the On/Off button until
the red power light and LCD display begin to
flash. This signals that you have entered the
Set automatic shutoff mode. Set the time
you want coffee to begin brewing by
following the instructions in “Entering Time
Set Mode.”
When the coffeemaker shuts itself off, two
tones will sound.
NOTE: Automatic shutoff may be
programmed either before or during coffee
brewing. If you program the auto shutoff
time after brewing is completed the unit
will automatically account for elapsed time.
For example, if you set the auto shutoff for
40 minutes and 25 minutes have already
elapsed, the unit will shut off automatically
after 15 minutes (40 minutes minus the 25
elapsed equals 15 minutes).

Key board and touch pad do not work


Did it shut off on the keypad? Sometimes things are being so frustrating that we forget that the keypad has a shutoff that can get bumped. Make sure it's on.

How to clean the coffee maker & set warmer


In order:
1 and 2) Clean the coffeemaker by puring in 1/3 caraffe vinegar, and 2/3 caraffe water. Either use the self-clean light or brew it as if it were regular coffee - just press the on button and then press the self-clean button, and it will begin.
3)
The Automatic Shutoff Time can be programmed
anywhere from immediate shutoff
after completion of the brew cycle up to four
hours. When the coffeemaker shuts itself off,
two tones will sound. Four hours is the default
time. The 0:00 setting shuts the unit off immediately
after brewing is complete. To check the
current setting, press the “On/Off” button and
the Automatic Shutoff Time will be displayed.
To change the preset time, press and hold the
“On/Off” button until the red “power” light
begins to flash. This signals that you have
entered the “Set Automatic Shutoff” mode.
Press the “Hours” and “Minutes” buttons
to scroll forward through the digits until
desired time appears. The first setting which
appears is preset at “4:00” and the next
display will be “0:00”, since four hours is the
maximum Automatic Shutoff setting. Pressing
and holding either button will allow you to
scroll continuously, slowly at first, and then to
accelerate to the rate of about three digits per
second. As the desired time setting approaches,
release the button and then press repeatedly
to advance one digit at a time.
The Automatic Shutoff Time (ASO) may be
programmed either before or during coffee
brewing. You may also re-program the ASO
time when brewing has been completed. If you
do so, the Automatic Grind & Brew™ will automatically
account for any time that has already
elapsed after brewing. For example, if you set
the ASO for 40 minutes and 25 minutes have
already elapsed, the Grind & Brew™ will shut
off automatically after 15 minutes (40 minutes
minus the 25 elapsed equals 15 minutes).

Good luck!
