Try removing the main battery and the CMOS battery (ie the battery on the mb). If you don't want to wait for 1/2 hour for the CMOS to discharge then short out the CMOS battery connections with a bent paper clip.
Then without instralling both battery, power up your laptop, you should then get into the BIOS, power off and re-install your batteries.

The battery is fully charged, and the ac adapter is plugged into the laptop, when i push the on button the laptop will not start


Remove the battery and power source. Remove the RAM and hdd. Power up with the power supply and it should do something. If it does, replace the RAM and hdd it should now restart. If nothing, check the GPU.

Why doesn't my HP 4620 print black ink


Either the BLACK INK CARTRIDGE is out of ink of it's possible the ink jets (they eject the ink onto the paper) are clogged/dirty. Your software under HP in PROGRAMS from the START MENU should provide a 'cleaning' cycle. How to Clean Print Heads is a link to help you with how.

How to remove a bios password from hp 6720s


Why can't people put a problem in the right catagory?
Generally, you can remove the Bios backup battery or use the jumper on the motherboard to reset the bios completely.
Google "reset bios" to get an idea of how to do it, or do the same in Youtube for a video. Lots of them are out there.

How do I get the battery out of my acer laptop


Your Model of Aspire has a different battery release method, see attached pic on how to do it. This is a pic from your User Manual, you can download it from here Download Acer Aspire E1 572
Manual
. I suspect that the information you have been given regarding battery removal and passwords refers to removing the cmos battery as in a PC in the hope that it will clear Bios activated passwords.

Button keeps blinking


It sounds like it could be either the battery is going bad and not holding a charge or the adapter is. I have had really good luck with similar problems going to places like Batteries +, and large electronic retailers, and my favorite the small local mom and pop computer store; where I end up asking them If I could try one of the adapters from the floor model to eliminate if is a faulty adapter. Other then that I'd if its not out of warranty contact Acers online chat support at http://us.acer.com/ac/en/US/content/service

How do i reset my computer to an earlier date?


Most computers have a RTC or "real time clock" in the BIOS. BIOS (or "Basic Input Output System") controls how data gets into and out from the processor (via keyboard, disk, etc.). Be careful making changes. The BIOS is normally only accessable when the computer is powered on or reset, and then only while performing the POST (or "Power On Self Test"). At this time your screen may display text describing memory, drives, controllers, etc. Some machine have a "silent boot" enabled which displays a manufacturer's graphic or logo instead of this data. It is during this time the the BIOS may be accessed. Depending on the manufacturer of your computer, a key (Delete, Escape, F1 or some other) or key combination (ALT + F1, ALT + S, or some other) will be needed. It is required to press the key or key combination prior to the Operating System loading message(s). This can be done be repeatedly pressing the key (or key combination) once every second (or two) during the POST. Holding the key(s) down the entire time - or pressing them too often will result in an error, and require starting over again.

Once the BIOS screen is presented, you will have to scroll the entire page(s) to find the clock. Most BIOS brands have more than just a single page of settings. Using the the up, down, left, right, PgUp, PgDn & Enter keys - navigate to the clock hours and minutes and adjust as needed. Make sure that you SAVE changes before exiting the BIOS screen. Upon exit, the computer will reboot with your settings.

Your Operating System may also provide a way for you to change the system time (and date) as well. Try clicking on the time / date to see if it will bring up a dialog box that allows you to make the change.

I hope this helps and good luck! If my answer was helpful, please rate it "4 thumbs up" Thanks!
