Question about Acer Aspire 5100-5022 Notebook

2 Answers

Acer 3100, NO Boot, keyboard locked out,

I have a Acer 3100 Aspire Notebook. w/ AMD Turion 64 x2, 512mg ram, XP-Pro Media Center SP-2. At present the system is all but dead.

Power-on OK
HDD & DVD appear ok
Getting power to USB ports
No boot screen
Keyboard dead

A few days ago I was hit by a backdoor virus. and believe this is the reason for my problem as it is a utility to tweak CP. I got the system back up one time and got rid of tha virus. After removing infected program II tried to restore my system to a point before installing the program. At this point the system locked and was forced to do a hard shutdown. My Acer notebook has never booted again.

I have re-seated memory and HDD Have swapped out HDD, removed battery and recycled power. and no luck there. I even powered up without HDD and got same results.

I want to know if I removing the CMOS battery would help? I can see the battery and have no problem trying, however it would be nice to have a case diagram for accssing the battery.

Help is needed in a big way!

I have acer 5020,hard shutdown,no power,no boot, keyboard locked, do you have the solutions?

    I have a similar problem.

    It powers on, the fan starts, heat sink heats up, optical drive and HDD spin up, just no video, no response to keyboard or touchpad. I tossed it in the closet for about a month because I was frustrated with it and I brought it back out again today.

    I hooked up an extra monitor to it and still nothing. I checked connections and went through everything but was coming up empty handed. Don't ask me why I tried it, but I tossed a Ubuntu disk in the drive and restarted it and after a few minutes I got a quick splash screen (acer one, but very fast to pass) then it gave me a messege like "last boot did not complete", and asked me if I wanted to continue or restart or something like that. I continued and it booted in to XP (after about 10 minute, and even then it took about another 10 to become useable). Everything looked just fine after though. All the hardware was working and running just fine.

    After I discovered everything was OK I rebooted and.... same thing as before, no screen. I tried to reproduce the same thing I did before, but nothing.

    I'm gunna take a shot in the dark and say that something isn't seated properly...

    The mb is dead. A very common problem, unfortunatley no research in the problem.

    I doubt the virus had anything to do with the computer not booting... sounds a little bit more of a hardware issue rather then a software.

    Have you tried taking out the battery and hooking up the AC adapter without the batttery hooked up?

    The battery on the laptop being dead doesnt really have anything to do with if the computer will turn on or not.. it just wont save your bios settings, which will reset everytime you turn off your computer. You could have a dead motherboard... but that is the last resort...

I have the very same problem. I think that my motherboard may be dead... The problem happened while listening to music through the sound output. Maybe the speakers drained too much current. I don't know... I'm just worried about my HD. I dont want to loose everything.

It is possible for a virus to infect the cmos chip, but i didn't think it was possible unless you were performing a bios flash. however, it may be possible that the virus found a new vulnerability through your tweaking program, if this brogram can change motherboard hardware settings such as front bus speeds...

Won't hurt the motherboard, just won't work if it isn't supported.

The 64-BIT Processor has nothing to do with it, it serves a different purpose specifically, to the OPERATING SYSTEM.

Acer 3100, NO Boot, keyboard locked out,

For my case I think its a bad BIOS.Normally its a hard step to reprogram a BIOS.But first try thet step you said about removing CMOS battery and leave it for atleast 1 day(Without Notebook battery or AC) if its doesn't then try to read this one.No harm in reading even thought its a HP website..
Best of luck,takecare.
