Toshiba Satellite A305 Sudden Power Failures

As stated I have a Toshiba Satellite laptop. It is pushing about 2 years old now and I have started to get small intermittent problems but none of them have really been issues until now.
(I am running Vista, SP2. I am a college student (digital forensics as it were) so she gets some bumps and bruises from being hauled around but overall I try to take really good care of my computer. Aside from one incident with a very small spill of juice and being moved around so much, I keep everything maintained - updates, security, keeping things dust-free and so on.)

Today when I started up my laptop (plugged in to the charger because it had been a while since it was plugged in so the charge was getting low I figured) I noticed it wasn't actually booting, it was off. At first I thought it was me not hitting the button but when I watched the whole process it was turning itself off - even the LEDs for the power connection and battery and so on.
This occurred several times at different points in startup - sometimes I couldn't even get to my BIOS password prompt; sometimes it was just after that, sometimes after the Windows login and so on. Of course it was also popping up those little ''Windows was shut on'' screens but I couldn't keep power long enough to scan anything anyway.
I tried taking out, air-cleaning and replacing my battery which helped for a while. Then it happened again while I was net browsing.
I tried starting up with the battery completely out, just on the power cable...worked for about ten minutes.
I tried starting up just on the battery, same thing.

I'm running low on ideas shy of taking my computer in and letting someone else mess with my baby. Has anyone else got ideas or seen this happen''

It's the " small intermittent problems" part that bothers me..It sounds to me like a BIOS virus..

second to that

check the power cord, sounds like it's running on battery, and the battery is low or bad and the computer is shutting down to preserve data..

check that your unit is not overheating, vents are clear-intake and out..overheating will shut it down

then your settings in the control panel- powersaver options- be sure full power is selected..

Hope one of these sugestions help and if it doesn't write back in, someone else has more ideas- I'm sure.

Good luck

How long ago? As the water in the juice evaporates, what is left-behind is the sugars, which could be creating short-circuits on the motherboard.

> letting someone one mess with ...

It might help to get a certified technician to disassemble it, clean it (Q-Tips and denatured alcohol), and reassemble it.

Probably, all your files on your disk-drive are intact.
So, a technician could copy all the files to either DVD-writable disks, or a USB memory-stick, or to an external disk-drive.

It works good on battery but when AC adaptor is plug in the laptop cuts out and restart by itself.

Problem description: The laptop shuts off when AC power adapter is plugged in. The laptop works fine on battery power but as soon as you connect it to AC adapter, the laptop turns off.
Possible cause: 1. Power adapter failure.
2. Motherboard failure.
Possible troubleshooting steps and repair solution: First of all, test the power adapter. Make sure the adapter outputs correct voltage. It's possible that the output voltage is not correct and the laptop shuts down to prevent the damage. Test your laptop with another known good power adapter.

If the problem still exists, even after replacing the adapter, most likely it's the motherboard failure. Replace the motherboard.

Toshiba satellite A305-S6857 - how to replace the power inlet (jack) that is broken

Replacing the DC Power Jack on this model of Toshiba Satellite A300 series, is SWEET!

{The Toshiba Satellite A305-S6857 Notebook PC, is part of the Toshiba Satellite A300 series of Notebook PC's}

No de-soldering, or soldering is needed.
The DC Power Jack is a DC Power Jack Harness.

The DC Power Jack is connected to a cable (Wires) that end in a connector, and the connector plugs into the motherboard.

To repair the problem you just replace the power jack harness.

A) Guidance given with instructions, and a pictorial guide, (Click on each photo to enlarge),

The above is Page 1.
To go to Page 2, and Page 3 ,click on the white page number at the top, or bottom of the page.
{Page 1::Page2::Page 3::Find another model }

Page 2, Step 17 shows you the DC Power Jack Harness, and where it connects on the motherboard. (Small white rectangular connector)

B) This is a link to a free Service Manual for the Toshiba Satellite A300 series of Notebook PC's,

Go down to the 11th line. The one that starts with Satellite A10.
Scroll across, and click on > A300

This is a PDF file.
Allow up to 30 seconds after you click on the file name A300, for the first page to come up.
It may also take additional time for the file to fully download.

C) Remove ALL power to the laptop before you begin.
Remove the AC adapter (Charger) and Battery

D) Observe Anti-Static Precautions

It is Advised to buy and wear an ESD wrist strap, and connect the alligator clip to a good ground source.

{For one example I connect the alligator clip to the metal frame of an empty desktop computer case}

Your body carries Static electricity.
Static WILL fry out (Short Circuit) the hardware components inside a computer.

Using an ESD wrist strap, and connecting to a good ground source, will relieve your body of Static, and help to ensure your laptop is safe from Static shock.

E) Use a multi-compartment container for the various screws you will remove.
Mark each compartment for the area the screw/s come out of.

There may be as many as 60 screws, and 12 different types.
Do NOT mix them up!

If no multi-compartment container is available, you can substitute with a clean egg carton.
Mark each egg holder.

F) Make a record as you disassemble. It's nice to have a record you can go back to in case you are interrupted, and to have a record that YOU understand.

Make notes and drawings, use a camera, or video cam if available.
{Use Good lighting}

From a quick search,
