20 Most Recent Toshiba Satellite 1805-S274 Notebook Questions & Answers

I had this problem for a LOONNGG time. I couldnt figure out what the heck was going on or why it was overheating. I almost resorted to buying a new computer, but thankfully I didnt. About 1am this morning it did it to me again. So i decided to clean the bottom and make sure it was clean. I cleaned it, and just out of curiousity, took apart the exhaust fan housing, and O. M. G. was there a TON of dust and junk in there. It took me about 45 minutes to clean it out thuroughly because I am not very computer savy when it comes to taking them apart and putting them back together correctly. But I would be my paycheck that if you took of your exaust fan housing, and then the individual covers for the fan and inspected the fans, and the exhaust ports themselves, you will find your problem. Since i cleaned it, it hasnt turned off once and the fans hardly run at all! I hope this helps guys!

mostly keyboard issue.

Surf to the Toshiba manufactures website and enter your model number so you can pull up your drivers and BIOS updates. Toshiba Laptops often require more BIOS updates than the avg laptop.

i dont think its the hdd. its most likely the cpu. clean the heat sink and see if the fan is still working, you may even want to clean it a apply new thermal paste

if this helps please take time to rate

Overheating When the CPU overheats then it will shut down (i.e. thermal overload) and won't boot up again until it has cooled down. If this is the problem is not fixed then the CPU will eventually fail.
A faulty fan causes the problem or the fan and heat sink assembly are clogged with dust.
Check the CPU fan to see if it spins freely, if not replace the fan.
If the fan and heat sink is clogged with dust the remove the dust and make sure the vents are clear and dust free. Use a small brush and can of compressed air to do this.

The problem may be related to a capacitor called NEC/TOKIN Proadlizer which loses its capacitance with time and causes such issues when AC is plugged in. One needs to replace this cap as shown here: http://gs138.photobucket.com/groups/q251/S1BXDWUERU/

If you are the original owner, Toshiba will unlock the bios code for a fee $100.00 a cheaper approach, go to www.ebay.com Type: bios password this will take you into a list of sellers to choose from, I suggest one that deals with Toshiba, "better chance of success"

make sure the battery is connecting properly and has charge

one bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect your hard drive boot up

test all leads that attach to your hard drive including electrical extensions SATA

the leads from your ((motherboard to your hard drive)) make sure they have a secure connection and are not faulty or just replace them they could be faulty

make sure all leads that are attached to your drives dvd\cd have secure connections and are not faulty or just replace them they could be faulty ?

make sure the CPU central processing unit has thermal grease and a dust free secure seating

even something as small as an electrical extension or a faulty fan lead can cause this problem computers need all of the data and electrical current to travel through every working device and to have an end for a computer to be able work properly

motherboard and a hard drive any leads between them will fail before your motherboard or your hard drive check all electrical extensions make sure they are securely seated even the cd/dvd drives need to have current go through make sure these devices are working

also check your computer ram and cmos battery to make sure they are securely seated and the battery has plenty of charge

some motherboards cmos batteries are soldered in

hope it helps

Toshiba keyboards are very easy to replace and they can be sourced easily from loads of suppliers. just browse the net and you will find them.
To fit, just turn it over and look for two screws usually in the centre of the machine. they will have a tiny picture of the keyboard next to them. Remove the screws. Turn the laptop back up the right way and the keyboard should just lift up. there will be a large flat ribbon cable holding it to the motherboard, (so don't pull on it as you will break the connector) unclip the connector and the cable will fall out.
To fit is just the reverse.

Good luck.

This is quite a tricky problem to fix unless you know what your doing. It sounds to me like an inverter problem. But it could be the LCD screen, the backlight bulb, or the motherboard. All can cause similar symptoms. Unless you want to try to change the inverter I found a website telling you how to: http://www.irisvista.com/tech/laptops/Toshiba-Satellite-A105/remove-replace-LCD-screen-1.htm If you are not comfortable in doing so I recommend not to change it as you may cause an even worse problem - In which you may want to hand it in to a repair company and tell them that you may think the inverter is faulty. To prepare you you may have to buy a new inverter.
PCHELPSTER from youtube, all the best.

because it's old sorry. this is just the way of many laptops. the only "light" in the tunnel is that it may be repairable and it might even be relatively cheap ($100 U.S.) but you will have to check the yellow pages and/or the news paper etc to find the guys that do it because the big computer stores will charge you ALOT more. hope this helps and good luck:)

It may shutdown when it gets too hot. Toshiba Satellite had some problems with this a few years back which involved a class action lawsuit. I had one of the computer that experienced problems and lost a lot of material which had not been backed up yet. I received compensation as part of the class. The lawsuit was settled, but I notice that the Satellite that I purchased since then will shut down automatically when it gets too warm. It helps to put it on a cooling device and I also turn on a regular fan and point it toward the computer when I can. If it is inconvenient to do any of this, I turn it off periodically to let it cool down. That way, I don't lose any data. Of course, I back up all data frequently.
