I have a Toshiba Satellite M45-S331 laptop. Started experiencing power issues. Whenever battery gets below about 95% it shuts off. I am running with ac cord connected. Also, the keyboard/touch pad will freeze just prior to shutting off. I attached a usb mouse and that seems to work even when keyboard freezes.

Hi,

Your concern (auto shutting down) with Toshiba could be caused by excessive power drain by some of the attached devices such as the WiFi, LAN among others. On the other hand, it could also indicate that the battery is already weak and constantly requires charging and at times eats up most of the power from the adapter leaving nothing for the motherboard to use. In some repairs I have done, switching off / or removing entirely unneeded devices correct the problem. In some instances, auto shut down is caused by dirty/clogged airducts/heatsink of the processor, failing blower/fan and/or poor ventilation.

Of course, it could not be ruled out that internal problem with the power supply/regulator to have caused the shut down. Alternately, there are some viruses and malwares that could trigger shutdowns.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

if its not under the laptop, it can only be under the keyboard.

SOURCE: I changed the inverted in my toshiba satellite

Sounds like the screen itself is bad or possibly the plug is bad to the inverter or motherboard.The videocard sounds like its ok.

Testimonial: "I tighten up the inverter connector and the screen worked, but for a little while. This helped me in the process of elimination"

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.
