The symptoms you described are normally common motherboard failure signs.
Try removing the ram and hard drive from the computer and then try booting the computer.

does it run with the power cord plugged in? if so your batterys dead, otherwise harddrive/bios/motherboard fault? is your power supply charging the battery?

After a normal restart yesterday, my Aspire One booted into just a black screen. No POST, no BIOS, no hard drive light activity, just the power button LED on and the fan running fast. I was not very happy…
I went to the Acer Aspire One User Forum and started looking thru the Hardware section. I found this thread Dead aspire one and it looked like many others had a similar experience. After reading many stories of warranty repair or replacement, I was just about to dig up my receipts when I found this post: Re: Dead aspire one.
It seems that a lot of people had success reflashing the BIOS from a USB drive using tools provided by Acer. I don’t know if it’s officially supported by Acer or if it will void your warranty, but if the computer’s a paperweight now anyway, what the hell?
It’s very easy to do, but the steps are a bit unclear so here’s my attempt to make the whole thing painless. This worked for me, but it might not for you, so do this at your own risk.
A working USB thumbdrive you can erase. I used an old 64meg.
UNetbootin. Download from here: http://unetbootin.sourceforge.net/
The files to flash the BIOS. I used the most recent version from here: http://sites.google.com/site/maclesblogspotcom/
Download all the files to an easy to find location.
Steps to prepare the USB drive:
Format the USB drive using the FAT file system, not FAT32.
Start UNetbootin and choose FreeDOS as the distribution. Screenshot here.
Unzip the BIOS files and copy them to the USB drive
Make a copy of the BIOS file and rename it as ZG5IA32.FD (this appears to be very important - my reflash failed until I did the copy & rename)
Reflash the BIOS:
Make sure the AAO is turned off, the battery is attached and the power adaptor is plugged in.
Insert the USB drive
Press and hold FN + ESC and press the power button to turn it on. Release the Fn & ESC keys. The LED in the power button will flash.
Press the power button again once and wait. Mine took ~3 minutes, but I’d advise that you let it sit there for at least 5 minutes just in case your’s takes longer.
When the reflashing is done, the AAO will reboot and, hopefully, you’ll be back to normal.
If it doesn’t work, try reflashing again. The keypress sequence is a little tricky.
If the second try doesn’t work, then you’ll probably have to send it off for repair.

Looks like you've had a bad day with computers! Let's see if we can take some of this on today...
On the first laptop (these ideas may work for both, but I'll address them the way I would my own, and we'll go from there), it looks like there is too much stuff being loaded into memory during system startup. This is not uncommon, particularly in computers which have teenagers as primary users.
I would restart the computer, and after the manufacturer's splash screen and before the Windows splash screen, hit the F8 key on your keyboard. This should bring you to a startup menu, which will be a black screen with white writing on it. You will be able to make your choice by moving up and down with the arrow keys on your keyboard. Choose SAFE MODE and hit enter.
If you do not see this screen, then you did not time the hitting of F8 corectly. You'll have to restart and try again.
Once in safe mode, click Start, then RUN. With Run open, type this command MSCONFIG and hit enter.
The next screen that opens is the configuration utility, which allows you to change the things that start with your computer. The last tab on the top should be STARTUP. click this.
Because we are shooting in the dark here, and we are not sure what is stopping the startup process, in the lower right corner of the window is a button that says Disable All. Choose this and click APPLY.
When the mouse comes back, click the next tab, which says SERVICES. Under the first window, you will see a small check box next to a line that says Hide All Microsoft Services. Place a checkmark here.
Again, in the lower right corner, click Disable All. Then click OK. When asked to restart, chose yes. This time the computer should start normally.
Now, this should start your pc, but you still have trouble with no AntiVirus software on your computer. The programs are there, they are just turned off. You'll have to open the program from the program files list, and enable it once again.
I'll comment on the other one after I eat dinner with my family.....

SOURCE: Compaq Presario F700 wont boot
I had the same black screen problem with my Compaq Presario f700.
I went to the HP website to troubleshoot and found that a hard reset fixes the blank screen issue.
To perform a Hard Reset, unplug the AC power adapter and remove the battery, and then press and hold down the Power button for about 6 seconds. This will drain any residual charge in the capacitors and reset the power management controls to their default condition.
This fixed my problem.
I hope it helps you.
