Will not start up, windows tryes to start then nothing. what is the problem?

no, there is no internal fuse, unfortunately- because this sounds like a dead motherboard. the aftermarket power supply could have been over-volting, or delivering unsteady power- burning the motherboard.

OR the old power supply shorted, and blew the motherboard's power circuitry, and you were just running off battery power when you first got the replacement.

please keep in mind that, at times, the physical power input jack on laptops can also break, or come loose from the motherboard.

remove the power cord, remove the bios battery, short the two contact together in the battery holder for a few seconds, replace the battery and power cord and try again.
if that doesn't work, start removing items/plugs (not the big 20/24 pin one) from the motherboard until you get beeping noises.
if still nothing then put everything back and try a different power supply.
if that doesn't work, your motherboard is probably dead.

you might need to change the battery, you can order them. here is amazons http://www.amazon.com/s?ie=UTF8&page=1&rh=i%3Aaps%2Ck%3Aps3%20controller%20battery

That is a signal that your battery is almost dead or drained. If you have the power cord plugged in and the battery is not charging at all, that means the battery is dead and you need to purchase another one.

In windows xp you should be able to click Start/Control Panel/Power Options. When the power options window opens click the Power Meter tab. It will tell you if your battery is charging.

Now to isolate if it's really the battery that's dead or if it's the Power Cord that's bad. You might really be operating on battery power even though you have the power cord plugged in.
1) Turn the laptop off and remove the battery. Turn it back on with only the power cord plugged in. If it comes and and boots up ok, then your power cord is ok.
2) Turn the laptop off and this time put the battery in, but leave the power cord off. Now hit the power button and see if it boots up. If it does that means you might have a little power still left in the battery, but since it was not charging when the power cord was plugged in, the battery is bad because you verified in step one that the power cord is good.

Your problem is far more than the battery. Your problem is the power cord. Laptops for the most part will work off the power cord even if the battery is dead or even if the battery is not in the laptop. Your power cord charges your battery and if it is bad it will not charge it. You've been working off your battery even though you might have had the power cord plugged in, but if it's bad and not charging the battery, the battery drains and then you can't get the laptop to power on at all. Go purchase a ac adapter and power cord that is designed for your system. Don't buy one that some of the big box stores sell that has a an interchangeable plug at the end designed to fit just about any laptop. Those will eventually burn *********** board out.

Your battery maybe out of charge. Thats why nothing happens when you press the power button. The battery may not be charging because the power cord might not be working. Try another power cord.

Try removing the battery and plugging the power cord and switching on the computer. If its the problem with the power cord the computer wont start. If it starts, the power cord is working fine.

yes it would need charging but as you have a cord it should work of the main electric. try taking out the battery and just using the mains

The Transport T2300 has an internal battery that will run the laptop for several minutes after the main battery goes dead. This feature allows you to save your work and shut down safely. If you run the laptop until both batteries are dead, even a brand new battery can't start the unit again. You have to follow this procedure:
1.Unplug power cord

2. Remove any attached periphal components including the cd rom and/or floppy disk module if you have one. Both remove with a push button switch located on the bottom of the unit.

3. Plug in power cord and charge the unit for a minimum of 24 hours straight. 30 hours is better. This whole time will be spent slowly recharging the internal back up battery.

4. Once that is done, unplug power cord again and reinstall any floppy/cd drives. Plug power cord back in now and charge for at least 24 hours again.

If your backup battery is dead, you can't charge the main battery or turn the unit on. The longer you charge, the better. We had one unit here that had to be on the initial battery backup for 72 hours before it finally took hold. Then, one overnight recharge on the regular battery and all was well.
If you need drivers or manuals for the 2300, all are available on cd at [email protected] for around $9.50 including shipping, handling, and owners manual

this will be easer than you think.
first unplug power cord,pull out your battery and test it by pushing the button on the battery. It will be dead. leave it out. plug in power cord, nothing should work. test your power cord. if nothing than test lower on the cord it might be the plug in that plugs into the laptop. what happens is the battery get to low and the lappy goes into a safe mode . you will need a charged battery to get it to boot.
