I have an e-machines M6811 laptop. Powers up and I get cd-rom activity but no post, no beep errors, no HD activity, and no video. Tried new memory but no luck. Can't even get into the bios. Just get a blank screen. I'm sure it's a system board issue but since I don't have the $$ for a new board I'm hoping someone can come up with another possibility.

Thanks

Rich, remove all memory, the battery, the hard drive, and pop open the cd rom tray; plug in the ac adapter and push the power button. If the power light and the fans come on but the system still does not post, then the problem is either the mobo or the cpu.
I feel for you brother. Best of luck.

i have tried the above and the same happens
does this mean the mobo or cpu is no good
i do have 2 laptops the same (GATEWAY MT6825B)
obviosly one working and one not working
i did swap over the batteries/ram sticks/and hard drives in both laptops
the working laptop still worked with the broken laptops hdd/ram and battery
and the broken one still didnt work with the good laptop bits in
what happens is
it powers up and hdd light comes on and so does the fan
but the hdd light goes out and fan stops, this is normal as i have tried it on the working laptop but on the working laptop it comes up with the press f2 for settings and press f10 for setup or what ever it says.....
cant remember the exact words
but it doesnt do this on the broken laptop
is there more than one fan on laptops as i cant see any more
someone did tell me it could be the cmos battery
but cant get into laptop to replace it
are they normall under the keyboard
any help would be apreciated

I have to disagree. I have repaired hundreds of laptops, and a cmos battery was never the cause for those symptoms. I have had units beep, complain and hang with an error, but there were signs of life. How many lapotp cmos batteries have you replaced?

by richard_lehr

I'll check the battery but I have to agree it seems doubtful. I used to be a repair tech back in the day and I've changed one cmos battery. I just wish I could find a schematic for this motherboard but I've come up empty on that.
