Question about Toshiba Satellite M45-S331 Notebook

1 Answer

My toshiba m45-s331 laptop keeps shutting off by itself... I was told by an IT tech that with the power or front lite being amber then turning to blue that it is a sign of my motherboard malfunctioning. It will not come on with the battery attached, I can remove the battery then plug in ac power an it comes on... It may fully boot, then it shuts off; what would you analyze this problem to be?

It may be a battery problem ...(the battery no longer holds the power values needed for it to work ..or may be a physical issue a bad wire contact or so .... If you think this is not the case and the battery is good..try to default the bios settings ..maybe you messed up and something enabled in bios case this..
Also try to look at the power management and see if it is not something caused by a setting in that area..I suggest to set them all to never shut down ..
Pay attention on the hard disk setting of the bios ..if you do not have the raid capabilities enabled..when you default them it may make changes that will affect your boot-up //(set them back to ide compatible if this is teh case ) ..
Also try another battery if you can borrow one or so ..and see if this will make any changes..
If t has any drivers for battery functionality ..try to download them from the support site and install them, ..This may fix the mode battery is charging ...or at least will give you a status info ..
If it works with the adapter in ..t may be nothing wrong with the motherboard. but a contact being loose or so ..and usually due to a heating issue ..

if you have an anti-virus and an anti-malware prog. installed, then update them and run them! you might be surprised at the amount of junk you have slowing your system down! also, click 'start', then 'all programs', then accessories, then 'system tools', then 'disk clean', after that runs and you clear out the 'dead-wood' (junk temp. files, etc.), then run 'defrag' hdd, next down from 'disk clean'. run 'analyze', if defrag. % is high, run defrag. may take a while, but will 'glue' your progs. closer together! and get rid of 'fragments' of older files.
if you don't have an anti-virus, i recommend 'a2'- google it and download. save it and install it. make sure you update the virus definitions before you run it. if you don't have an anti-malware- then i recommend either 'ad-aware' or 'spybots&d', make sure you get the right site for it, there are sites that have very similar names! as 'a2', update definitions before running!! you will be shocked at how many 'baddies' you have messing with your OS! these are all free! for the basic service. you can try them, and if satisfied, upgrade ( for a modest price), for expanded coverage- but the basics work quite well.don't fail to 'immunize' on spybots&d, after you download new definitions! you may have to click on immunize a second time to finish the process! this helps protect against future installations of these 'mal-wares'! quite a bargain for free-ware! i've used them for several years, and find that they work quite well!
good luck!

When we talk about laptop won't boot up it is a hardware failure.

First of all, most of the hardware failures that are going to be presented in this article require you to disassemble the laptop and work on its internal components. Because of this, you need the required components to take the laptop apart (such as screwdrivers, etc.) and space, lots of space. If you don't have a workbench, then working on that large table in the living room should do it.

Second of all, you need to be extra careful about ESD (electrostatic discharge). Sure, this is important when working with a desktop system too, but you really shouldn't consider this as some sort of overreaction or waste of time. A few anti-static conductive bags should suffice. These are going to be useful when you take apart components from the laptop and you need a safe place to put them down.

If the laptop does not power on using the batteries, then try to power it using the AC adapter. Pay attention and see whether the LED on the laptop lights up, signaling that the adapter was detected. If yes, then your power jack works. If the notebook still does not power on, disassemble the laptop and remove the batteries. Look first for the CMOS battery and take it out.

Your best bet is that the problem is memory-related. What you need to do is re-seat the memory modules. If there are more than one, then try swapping them between each other and try different slots. Try booting again. If it does not work, then try running with only one module - this way, you can tell whether one is faulty.

Disassemble the laptop and remove the HDD, CD/DVD drives, and the modem and/or wireless card(s). If possible, take out the sound card module (if separate). To minimize the possible causes, you may disconnect the LCD panel as well. Try running this way. If it does boot, then try connecting each connector one at a time, booting up in between to localize the problem.

Good luck and take time to do a hard troubleshooting this trouble is not easy as well. You need to be care full in removing the some parts so that the other will not affected and being damaged.

SOURCE: how can i reset my bios on a toshiba m45 s331?

If you have access to your BIOS, try this first to avoid opening up your notebook.

1. Turn on your computer and press the relevant key to enter the BIOS. I think with Toshiba, this is one of the function keys, but it could also be the Del (delete) key.
2. Go to the last tab or page of your BIOS.
3. Select an option similar to "restore factory settings".
4. Save your changes and confirm your selection if necessary. This will often be combined with the process of exiting a BIOS. Some BIOS types may have this as a separate option such as "F10: Save Changes".

There are two other procedures you can try, but I don't have enough space to write them here. Please contact me if this method doesn't work. If it does, please rate, thanks.
