Acer 5920g shutdown after 1sec at startup

April 22, 2011 at 10:36:01
Specs: Windows 7

The Problem:

Yesterday my 3,5 year old 5920g died completely. I tried to boot, the power light around the power switch lit and so did the multimedia key lights, i heard a faint noise (probably the harddrive starting) then after about 1 sec all lights went off and nothing happened anymore. The screen was black the whole time. No beeps.

After several attempts the problem is allways the same.

I havn't installed any new drivers, fidelled with BIOS or anything like that lately. This was completely unexpected. The only other problem I have had with this laptop was with the LCD backlight power cable and I very much doubt that that has anything to do with this.

I've tried:

Reading forums and the user manual (Didn't find much relating to my problem.)

Hard reset (Take out battery & power cable and press start button for ~60 sec)

Starting with/without battery/power cable

So, what I want to know is:

Where should I start looking for the problem?

Is there any way this could be BIOS related or is it definately a hardware problem?

Any advise on how to diagnose the problem / rule out causes? (preferably without taking the machine apart)

A big thank you in advance for those who care to give some advice!

... does it stay on if you can [enter] your bios?

... if it does not "stay-on" while you're in the bios it maybe power related, take a look at this thread.

Like I said it stays on for 1 sec. So there is no time to get into BIOS.

About the power supply: The L-shaped light that indicates that the power cable is plugged in lights up as it should when I plug the power cable in. Also the battery charge light works as it should, indicating that the battery is being charged (orange light) and that it is fully charged (green light). This makes me belive that if the problem is indeed power related the fault is located after the power cable & battery, perhaps in the power supply - motherboard connection. Or maybe the mobo is busted alltogether.

I'm not too eager to open up the laptop and fiddle with the insides because I would'n really know what I am doing or what to look for. Also I don't have a voltage meter so I can't test the output of the power cable or the battery.

I've been doing research for the entire day now, and it seems there is a huge amount of things that might be wrong. (Power, CMOS/CMOS-battery, Mobo, corrupted BIOS and even broken CPU) What I hope to do is somehow narrow down this list to the most probable causes before I start opening up the laptop or ordering parts etc.

But thanks for the answer anyway.

... sounds like you can "rule out" a jack plug problem as you say it charges up the battery.

... strange that it'll stay on for 1 sec, guess you've tried without the power adapter hooked up(?)

... and vice versa, battery removed just off adapter(?)
