My dyson Max 08-21663b WHEN FULLY CHARGED I TURN IT ON AND IT RUNS FOR 5 SECONDS AND GOES OFF AND DOES THE SAME THING REPEATELY I BELIEVE ITS MY BATTERY PACK WHICH IS A 6 CELL CAN YOOU ADVISE ME?


Yes the battery pack would be the most likely culprit here. Go on eBay and buy the correct battery cells and build one using the old one as a guide. This method will save you about 50% over trying to buy a make up replacement if available. This is an easy job, just take your time, buy batteries with solder tabs.

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.

Does it actually have a wireless network adapter? Check the network adapter settings. Does it show both LAN and wireless? If it does you may need to use one of the Function keys to launch the interface to turn on the wireless.

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

Freezes on the warm boot screen MC9000


This can be for a number of reasons.

First thing would be to try and cold boot the device:-

Remove battery half way, hold power button and trigger, push battery in fully until click and then release power and trigger

If that fails next thing would be to try and re-flash the operating system. This is done by using an SD card and loading the latest operating files onto it. The SD card slot is located under the keypad. A cross head screwdriver is required to remove the keypad. Search on symbol software download site for the latest. The download also has a readme with detailed instructions. Once the files are on perform a cold boot.

Remove battery half way, hold power button and trigger, push battery in fully until click and then release power and trigger. Drop the terminal in a cradle so that it runs on external power.

Hope this helps.
