    I have the same problem.. I've tried new AC adapter. I think the problem is with the internal power supply, possibly the mother board.

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.

Will not start up


hi , Reuben

I would suggest you try safe mode.
Safe mode is a troubleshooting option for Windows that starts your computer in a limited state. Only the basic files and drivers necessary to run Windows are started. The words "Safe Mode" appear in the corners of the display to identify which Windows mode you are using. If an existing problem does not reappear when you start in safe mode, you can eliminate the default settings and basic device drivers as possible causes.
If you don't know the cause of the problem, you can use the process of elimination to help you find the problem. Try starting all of the programs you commonly use, including the programs in your Startup folder, one by one, to see if a program might be the cause of the problem.
Follow the steps to boot the computer in safe mode with networking:
1. Restart your computer if it is powered on.
2. Tap the F8 key after your computer initially powers on.
3. Once you see the Advanced Boot Options menu you can stop tapping.
4. Use the up/down arrow keys to highlight your selection.
5. Select Safe Mode with Networking and press Enter.
6. You should see drivers loading, and then please wait.
7. You should then be at the Welcome Screen.
8. Logon to your computer using an account with Administrator privileges.

What is the difference between windows 7 editions: starter, home basics, home premium,ultimate, professional,interprice?what is the difference between service pack 1 & 2???pc


Since October 31, 2013, Windows 7 is no longer available in retail (except for the Professional edition preinstalled):[6]
Windows 7 Starter Windows 7 Starter is the edition of Windows 7 that contains the fewest features. It is only available in a 32-bit version and does not include the Windows Aero theme. The desktop wallpaper and visual styles (Windows 7 Basic) are not user-changeable. Microsoft originally intended to restrict users of this edition to running three simultaneous applications but this limitation was dropped.[7]This edition was available pre-installed on computers, especially netbooks, through system integrators or computer manufacturers using OEM licenses.[1][8][9] Windows 7 Home Basic Windows 7 Home Basic was available in "emerging markets", in 141 different countries.[10] Some Windows Aero options are excluded along with several new features.[1] Home Basic, along with other editions sold in emerging markets, include geographical activation restriction, which requires users to activate Windows within a certain region or country.[11] Windows 7 Home Premium This edition contains features aimed at the home market segment, such as Windows Media Center, Windows Aero and multi-touch support.[12] Windows 7 Professional This edition is targeted towards enthusiasts and small-business users.[1] It includes all the features of Windows 7 Home Premium, and adds the ability to participate in a Windows Server domain.[1] Additional features include support for up to 192 GB of Random-access memory (increased from 16 GB),[13] operating as a Remote Desktop server, location aware printing, backup to a network location, Encrypting File System, Presentation Mode, Software Restriction Policies (but not the extra management features of AppLocker) and Windows XP Mode.[1] Windows 7 Enterprise This edition targeted the enterprise segment of the market and was sold through volume licensing to companies which have a Software Assurance contract with Microsoft.[1] Additional features include support for Multilingual User Interface(MUI) packages, BitLocker Drive Encryption, and UNIX application support.[1] Not available through retail or OEMchannels, this edition is distributed through Microsoft Software Assurance (SA).[1] As a result it includes several SA-only benefits, including a license allowing the operating of diskless nodes (diskless PCs) and activation via VLK.[14] Windows 7 Ultimate Windows 7 Ultimate contains the same features as Windows 7 Enterprise, but unlike the Enterprise edition, it was available to home users on an individual license basis.[1] Windows 7 Home Premium and Windows 7 Professional users are able to upgrade to Windows 7 Ultimate for a fee using Windows Anytime Upgrade if they wish to do so.[1] Unlike Windows Vista Ultimate, the Windows 7 Ultimate edition does not include the Windows Ultimate Extras feature or any exclusive features as Microsoft had stated.[1] All editions will receive Mainstream Support (new features and bug fixes) until January 2015 and Extended Support (security updates) until January 2020.[15]

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

Removing bluetooth chip


Without knowing what the desktop computer motherboard is, I\'d only be guessing as to location of Wi-Fi chipset.
However even if I knew the motherboard manufacturer name, and model number; the point is Moot.

A) You remove that Wi-Fi chip, and kiss the motherboard goodbye.
It\'s designed into the circuitry of the motherboard.

Isn\'t going to be jumper wires taking it\'s place, and making connections to circuit traces on the motherboard.

B) Do you have a wireless router?
Dunno.
Do you have a wireless connection set up?
No.

You can use just a LAN connection. (Hard wired)

C) Suggest if having a Bluetooth option on your motherboard is not an option then use a different motherboard that doesn\'t have that option.
