Acer laptop powers on - no screen, no processing

I don't know what happened, but my laptop's not working.

I was using my laptop as a desktop computer (no battery) when I accidentally switched the switch off. After switching it on, I tried to turn on my laptop and the first thing I noticed was the blank screen. Then the power turned off, and then turned on again. The fan is working, but nothing else is. I don't hear or notice any processing, so I'm pretty sure nothing's working right except for the fan and the lights indicating that it's on.

I tried to reset the laptop by disconnecting it from power and then turning it back on after 30 seconds - but no luck.

Can anyone help me? I have an Extensa 4230 by the way.

 

you can try removing your ram sticks. a friend of mine had a similar problem and finally he found out that a ram stick was to blame for that

 

No luck on the RAM sticks. Thanks for the suggestion anyway.

 

There is few options left to try ..

First , the external power supply , could be damaged from overheat , as you operate it all the time .

Next , could be the power plug on the laptop.

I those two , does not do the trick , could be motherboard damage ,
due extreme use , with out extra ventilation .

laptop working as a desktop , needs cooling pads 100% ,
no one ever told you that ?

 

Fourth, could be a damaged BIOS. Search for an emergency flashing procedure for your notebook.

 

As far i know , Bios does not fail by it self .

Any way , lets hope that is something from the list , of the other three.

 

I've heard of some that did. Might be this newfangled EFI stuff.

 

If we get at hardware level , most issues comes , because the power plug ripped off , not supplying enough current .

Or , because the power plug ripped off , near by components , got burned.
and they do not supply some voltages .

In this extreme case we replace the MB , there is no hope for cheaper fixes.

My Laptop are healthy , but still got a space power jack ,
it feels better to have one near by , even if costs as 4 GBP = 5 EUR

Not sure about what you guys suggested, but here are some observations I've made when trying to diagnose what's wrong:

1. When plugged in, the laptop powers on, then turns off after a few seconds. Then it turns itself back on and stays on.
2. When using only the battery, the laptop powers on, then turns off after a few seconds. It stays off.
3. The DVD drive works (it even reads DVDs), fans work, LED lights on, but no processing.
4. When battery is attached, it charges when the laptop is plugged in.
5. Keyboard does not work.

I'm not about the emergency flashing procedure, but I can't get into BIOS since I'm pretty sure no processing is happening.

 

This thing happened to my friends Acer Aspire One. Try a BIOS update if possible, because that's how he fixed it apparently.

 

How do you do that?

Anyway, I just noticed that I still have warranty, should I just send it in? If so, does anyone know whether Acer will do a factory restore if they fixed the problem? I really don't want them to do so...

 

Just send it in. They'll fix it.

 

ACER are obligated to load the default OS .

Remove or backup , any files you consider as useful .

 

Not that easy on a dead notebook

So removing the HDD and putting it in an other computer or using an external HDD housing is the only way to do a back up in this situation.

 

I placed a 1GB RAM on my laptop. Is that still OK for warranty purposes? I read in the document they sent me that it is up to the repairer's discretion... I'm not sure if I should remove it or not...
