First disconnect anything connected to the laptop not necessary for booting.

Next, when you boot start slowly tapping F8 function key after the BIOS loads, but before you see anything that says Windows.

A menu should pop up. Select Last known good configuration that worked from the menu.

If it still reboots, use F8 to get to the startup menu and select Safe mode.

If you can get to the desktop now in Safe mode, try running a System Restore back to before the problem occurred.

Go to Start > Programs > Accessories > System Tools and select System Restore.

Follow the prompts and select a bold date before the problem began. After the reboot the problem may be resolved, but you may have to re-install any recently added software.

If still no go, boot to the Windows CD and choose to run a repair.

Let me know if you need more help.

Acer Aspire AX1300-E1820A will not turn on. even if hot wired, I didnot back up my files Help please


Worst case scenario: extract the hard drive from the Aspire (usually its just 2 tiny screws holding
the HDD), and plug this PCMCIA-bus drive into another (functional) laptop. Windows will
mount the drive (but not load the OS). Extract the files using the functional PC's operating system.

In future, always back up your files, or even better - keep no files on the laptop at all - do this
by storing ALL your files to a flash drive. That way, the system can crash an any time (and they do),
and you lose nothing.

Laptop wont turn on


What I suspect,is that the at the exact DC Port where you have to plug the adapter when you want to charge your laptop, some of the internal components are burnt. It might not be more than 2 though, if you can trace it very well. So don't consider changing your motherboard yet, until you have explored ALL possible options.
I wouldn't know if you can actually do this by yourself, or through a VERY good technician, who can help you to test the components inside the laptop, just at the tip of the DC Socket Port (but Inside the laptop). I handled a case like this before where I just had to change a very small capacitor inside the system at the exact point where the DC Current enters the Motherboard panel inside...and the laptop started working perfectly well...funny enough the owner was so happy and is still using it till today!
I would suggest that you get a good technician to try that for you...I really wished I could do it for you...but I'm sooooooooo far from your country...lol :)..(Nigeria). Hope this helps you better.
Sorry about the problem...trust me I understand!
Goodluck!

No power


HI,
you haven't mentioned clearly is the laptop in on state or are the batteries able to give power to laptop to start

try this solution if you have checked that the Ac Adapter is finr

take out the battery from the laptop and then plugin the AC adapter and then try to start your laptop

if your laptop starts without the battery by getting power through the Ac adapter, most likely your battery is Bad, get it replaced, if it doesn't start then it can be power circuit on the motherboard or the connectors you should get it checked from a technician.

If you think my solution was helpfull please do rate me

Acer Laptop Does not power ON At All!


Either the laptop has gone bad or the power supply has gone bad. You could buy a universal power supply at Best Buy, test your unit and then return the power supply. Not very moral thing to do but it will tell you if its the supply or the laptop. If it is the supply then you'll have a spare.

Power supply


Eric, your battery is probably falty, prompting the circuit to report fault, until power from the main substitutes the battery. I would get it tested and replaced.
