Computer won't switch on

Hi,
Your computer may be in sleep mode and have a software or resource conflict, when this happens turning the power on returns you to the problem instead of restarting the system. To clear the condition, press Ctrl, Alt, and del simultaneously for 10-15 seconds. Then shut down the computer via software....

Just try this and i will give you the next step if this doesn;t work... Please let me know.

From what you describe , it appears that there is a fault on power circuit on motherboard.
That is a technician's job and most repairre will go for changing the motherboard. That is very costly. In that case you would be better off buying another laptop.
As for your data on hard disc, you need to remove the hard drive connect it to another laptop or desktop computerby means of a connector.This can be achieved by 2.5" IDE to USB 2.0 Hard Disk Drive Caddy HDD Enclosure. These can be bought for about £5 in U.K.
Once connected you will be able to lift the data on to CD or USB memory stick.

First of all, since you mentioned that you haven't backed up your data, you can remove your hard drive and slave it to another hard drive or using a variety of methods like an inexpensive 2.5" hard drive case with a usb connector and then just connect it to another computer as a removable drive. After saving your data you can return to the problem with the computer in our free troubleshooting forum where you are less likely to receive so many wayward proposed solutions. Thanks for using FixYa and repost when you are more relaxed. This is not a power supply or battery problem. Steve Medley 

As soon as you press the power button, press f10 a few times which should take you to a boot screen describing the ram and other things about your computer. If you are able to get to the screen, you should be able to save and load your computer to the normal screen. If you can not, you can get your hard drive backed up which will save all of the information that was on there before to another hard drive so you can have all of your old stuff saved.

 remove the battery from the laptop and see if it will start up on ac power only a bad battery will give you a similar symptom.

Try a new power supply.if thats not it let me eknow i have a couple other ideas

As far as the data back up is concerned you can back up by removing the hard disk and put it the laptop external drive casing then attach to a system, and for system not working try removing the RAM, its on the back of the laptop with a comb like sign above them, if this also not solve your problem its better take it to the technician, then its the problem of motherboard

In very rare cases, the battery pack of your PC may stop accepting a charge, i.e., the battery stops working and no longer supplies power to the computer. To minimize the risk of ever experiencing this problem, we strongly recommend that you download and install the latest BIOS by clicking the 'Downloads' link that will appear when you are finished reading Support News.

i would suggest replacing the battery pack either through toshiba or a third party battery maker. There are several battery-pack recalls out for this model.
Regards.

Hi,
    There could be two problem related to this situation No. One- RAM could be malfunctioning and the second one is that change the cell of baiso which need to replaced.
    If you can open it by your self then open it unplug the RAM and then re-adjust the RAM again.And if you are not able to open it then contact any expert nearby to you.
  Thanks

Hi,

Initially, a couple of things you can try:

• run the laptop on the AC adapter only (batteries removed);
• re-seat/clean the memories. Invert the laptop. One of the squarish panels with locking screw(s) would hold the memories. Reference this page for illustrated instructions;
• remove any of the other devices attached to the laptop both internal and external (printers, wifi, networking). For the WiFi and networking, pls reference the same page as above;
• Worst case scenarion, remove the Toshiba's hard disk, gain access to a 2.5 to USB adapter and backup your important files.

1. Disconnect the power cable, battery and all external device conected.
2. Then press the power button for 5 seconds
3. After a minute connect the power cable and check if the system turns on.

The above step is known as power flea.

If the above steps do not work, turn the laptop upside/ down and towards the centre unscrew the cover and reseat the memory module. The card will be green in colour, Take it out and then push it back in.

If you are not very familiar with how to reseat the memory module, I would recommend you to contact some local tech shop.

Thanks

If the power LED lights up it indicates that the laptop is getting power from the AC adapter. Most likely there is nothing wrong with the adapter but just in case test it with a voltmeter to make sure the output voltage is correct.

Also try this. Unplug the AC adapter, remove the battery and wait for 1-2 minutes. After that plug the AC adapter ans try starting the laptop again. Sometimes this trick helps.
It also could be a memory related problem. Try reseating the memory module, just remove it from the slot on the motherboard and install it back. Try installing the memory module into the other slot (if it’s available). If you have two memory modules installed, try removing them one by one and start the laptop just with one memory module installed.

If the laptop starts fine with one memory module in both slots, but will not start with the second memory module in both slots, the second memory module is faulty. Replace the module.

If the laptop starts fine with both memory modules when they are installed in the slot A, but will not start with both memory modules installed in the slot B, the slot B is faulty and you’ll have to replace the motherboard or use only one memory slot.

Try plugging the adapter without the battery inside.

If it starts you have a faulty battery.

If it does not start at all , no light or power at all, then you have a faulty adapter, and the battery is drained.

If you get lights and there is power, then the computer has an internal fault.

Try removing RAM modules and restarting the computer with only one RAM module.

If it still does not start the computer must be taken apart and tested by a technician, probably it has a faulty motherboard.

Just remove the battery for some time around (30 minutes ) and reinsert it and switch on your system .

If this doesnot work you need to dismantle your notebook to check for any loose connection .

There might be sum losing of data bus (wires) so remove all data wires and plug them again or remove the RAM and plug it again that will fix your problem 
Thanks
