Acer Aspire M1100 no signal to monitor when starts
I bought this Acer computer one year ago from Future shop. Now there is a problem to start the computer. Sometimes the monitor shows "No signal" when I start the computer. However the computer is running, HDD is working, DVD-ROM is working. When I reboot, it works nomally without doing anything.

Any time a monitor says "no signal" that message is originating from the monitor itself, and not from the computer. A monitor in a room by itself with no computer will say "no signal" for a brief time, if it is turned on. So, if you have tried other monitors also with no luck, then the problem is either the video adapter of the computer, or something that is keeping the computer from booting in the first place (power supply, hard drive, memory, motherboard). A power supply can be tested with an inexpensive tool. Everything else needs either a swap out with a known good stand-in, or else an expensive tool to know if it works.Does the fan come on when you turn the computer on? If so, maybe more likely to be the motherboard, hard disk, or memory. If not, more likely to be the power supply.
My Acer Aspire M1100 would not boot and had no signal to the monitor. I thought the video card or motherboard had gone bad. I tinkered with it for over 2 years (yes I'm hardheaded) and finally realized the processor had worked itself loose. Reseated the processor and it works fine again. Hope this helps someone.
by default the hard drive should have a recovery partition. go to the support section of the manufactures website and you should find detailed instructions of how to boot to the partition. if that option has been corrupted, you can purchase a recovery disc directly from acer. i've ordered nearly a hundred for customers in the past and have never paid more than 20.00 for a disc or disc set.
below you will find a link that will allow you to enter your product serial number and direct you to the purchase of a factory recovery cd/dvd.
Check the cable at both ends for a loose connection. Thats all sounds like it came loose. If you have a good connection at both ends than the computer video card is bad, but sounds like a loose connection.
Unfortunately Acer no longer has recovery media available for this model Aspire. However they still have the drivers available for download so, the easiest way to get this machine as close to it's original condition as possible is as follows;
First and formost: Make backup copies of all file, pictures, music, videos, etc. that you need to keep.
Next: Download the drivers for this system by going to www..acer.com. Once you're there, select USA and click on the Service & Support Tab and click on the driver download link.
Then, make the selections for you computer i.e.; desktop, aspire, m1100, and windows operating system.
Now download all of the drivers you need for your computer and put all of these drivers on a cd, dvd, or flashdrive for later use.
Re-install Windows and allow the installation process to re-format the hard drive during the installation.
Finally, re-install any programs and data that you have and install the drivers.
Take your time and it should all fall into place. It should all take you a good half a day or less. Good Luck!
If you can connect your VGA output to a regular desktop monitor and it works during the startup process, then it is probably you LCD screen. There is no way to know for sure that it is the backlight unless you replace it.
