Hi everyone,

I have read some of the threads and none of them really answers my issue.

Current Hardware:

Toshiba Satellite A135-S4437 15.4" Widescreen Notebook PC (Intel Core Duo Processor T2250, 2 GB RAM, 160 GB Hard Drive

If you need more info just ask.

Ok so here is the problem, I was working on the laptop the other day and then decided I didn't need to have it plugged in, so the battery died and then I decided to go to bed...I woke up and then plugged the laptop in to recharge the battery, (which I do like every time it dies) I know the plug works and I know the battery was fully charged, when I got home after work I decided to take the laptop and use it to do work.

Then when I pressed on the turn on button it strts to boot up for 3 secs and then shutsdown, I ususally hear the fan start and then the hard drive kick in but nothing this time, it just died, I tried it with the adapter in and without, I tried taking the batterie out and the hard drive and it does not seem to work.

I am just stumped at how to start this computer, I do not have a floppy drive so cannot make a disaster recovery disk unless I can burn it on a cd which for that I have my desktop.

I am very confused as to what is happening, I do have a intermediate knowledge of computers and how they work, but nothing too fancy....If someone guides me through a troubleshoot process I will be able to do it.

I appreciate the time you guys will take to help me.

I am probably not the best person but several issues will need to be answered at some stage and that may get others involved. there was nothing on the Toshiba site

We are assuming that the computer died from a battery failure could it have been a virus?

the 3 second start and close suggests a possible hardware problem. the only way to check this out is to obtain any boot disk just to test the system. I note you are in Cambodia and I imagine it gets quite hot there and you may have a hardware failure from heat stress. was it hot at the time as often the specified operating temp for these laptops is 40oC not to be confused with the CPU operating temperature.

Just some thoughts to get you started so any boot disk will do to eliminate hardware.

The most common cause for a laptop computer not turning on is because there is no power supply. When you are connected to the power adapter then the battery will re-charge but the computer will also power on even if the battery has no charge. There is a very vulnerable connection to the MOBO where you plug in your power adapter. Knocking it can break the connection to the MOBO and so the system will not get power nor will the battery charge. You have said that your computer turns on momentarially. This is probably just because you have a very small residual charge in the battery. However this is not enough to start up the fan etc. and the IO systems.
Sometimes you will be able to notice that the power plug is loose?
My advice to owners of laptops is 'never move the computer when the power jack is plugged in'.
The only fix for this is a new MOBO, or a very clever electronics technician who may be able to use araldite to glue it up again..

Only read the manual as a last resort.

Alright, we have taken it apart and checked the battery, power pack, hard drive, ram and CPU...all of them work fine...

Now we think it's the motherboard...eishh i know those are costly and crappy to get fixed...any ideas at what it could be?

Note jules comments. There is an extensive thread on Dell inspiron 1150 elsewhere on the HWA forum with MOBO and power issues. there is good info there on repairing the board VERY carefully with solder and sparing use of araldite if physical repairs to connector bodies are required keep it away from any electrical connection.
