I purchased this laptop 9 months ago. Over the past few months the fan has been getting louder and the thermal shutdown more regular. It doesnt cause a problem if the laptop is not on charge. But the moment I use it and charge at the same time I get about 15 minutes before it goes off on me. I wait 5 minutes for the cool down , then start again.

That was until I read the postings here.

A 10 minute job has saved me many headaches. I took the srews out from the plate near the back air outlet, popped it off, took four screws in each corner (black screws) from the brackets underneath. The copper heat defuser then pops upwards with a bit of encouragement. Attached to this was a three inch long band of dust/fibres, this was half covering the front of the defuser. No wonder it kept overheating . A quick blow through and I just fitted it back.

Now the fan is quiet whilst it runs, the bottom of my laptop doesnt get hot near the back and I have just spent 2 hours using it WHILST on charge. Just happy I aint got to send it off to TOSHIBA....

Thanks to all especially Fran Fernandez for his clear instructions.

I thought I was going to have to bin this Satellite A30 - now it is working as good as ever, and the fan isn't even on all the time like it was. My tuppence:

1) Problems finding a T6? Me too, so I used a 2mm flat headed precision screwdriver instead, which worked with no problem at all.

2) Yank out the heatsink/processor. Well, I got away with it, but yanking it back in? Ha ha! It turns out that there is a locking mechanism for the processor, which needs to be turned to unlock before "yanking" it out, and back to lock when replacing it... Luckily it didn't break when yanking it out.

3) Compressed air - you gotta be kidding. It didn't take much effort to peel off the thin layer of carpet that was attached to the back of the heat sink, totally blocking the airway...

Hi everyone
First of all I am so happy that I have found this site and specifically this forum.
I've got a Toshiba Satellite A30 roughly 15 months ago. After 10 months of being used, my laptop started to shut down after running intensive process. Specially when I was running any CDV/DVD media my system crashes without any warning message. Other than intensive processes, the laptop can run for hours and hours...
Because at the time of having problems with my laptop was still under warranty, I send it for repairing. Toshiba Service Center's report stated that they had to change the motherboard?
The problem was solved but after 3 months the laptop started to have the same issue. Shutting down after intensive activity.

Of course because right now my laptop is out of warranty and not crazy to pay to having changed the motherboard again, I began to look for any other solution up.
Reading this forum, I found among to many posting with the same solution, I followed one of the first one posted by Erol.
I removed the little back cover of the cooling system, yanked out the heating sink and blew compresed air through the fan casing.
The hardest part was to find a T6 Torx. For anyone living in Canada, I found it in Canadian Tire store.

Apparently the issue has been solved. After almost four hours of intensive activity inclusive reproducing a CDV the system keeps up and running. The system is running connected directly to power supply and with battery with no problem.

I hope this will be a permanent solution. I am scared to buy other Toshiba Satellite.

Thank you

I have a Toshiba 1905-S303 bought Dec 2002 and had the overheating problem 2 months ago just after 2yr extended warranty. Thanks to the advices on this board, I bought the Torx T6 from Home Depot, opened the CPU case and cleaned the heat sink. That improved it. I also have a BYTECC laptop cooling stand from Micro Center, which helped a bit, but now mainly serves as wedge-like base for better keyboard angle.

Two days ago, the laptop went dead suddenly. When I turn it on, I could see the power light on, hard disk light on briefly then no sound -- only the fan comes on after 10 seconds. I removed the battery, memory, HD, etc. in sequence -- no luck.

Last night, I tried turning it on while wiggling the speaker grills as if I am pulling them up. Suddenly it booted ok; so I backed up the entire hard disk. I am wondering if the speaker grounding problems reported for the later models (A65,A75) are in the 1905 series also.

This morning, same problem while booting it. Called local authorized center and was told about a 5-day turnaround. I tried gently pulling each speaker grill with the top lid closed; it came out easily. I see the speaker unit in black plastic connected by wires from below. There is a phillips screw on one side and a plastic tab on the other holding this speaker unit. Near the screw, there appears to be quarter inch wide flexible copper strip connected to the aluminum base on the laptop. I am wondering if this is the grounding mechanism.

Could anyone shed a light on how to properly ground this or fix the statis problem? With the speaker grills out, I still can not boot the computer right. Whatever I did yesterday to get it working, I cannot reproduce it now. Perhaps I should just give it the repair center technician.

Will appreciate any help.

Thanks
Srini

Hello Satelite users, (this is an easy fix. It hasn't happened again)
Bought the Toshiba, because of their tremendous reputation in laptops. Was blown away when we had the thermal shutdowns. Also, the retailer started slashing the price on the Satelite A60. Went to Toshiba support site for our model. Toshiba knows there's a problem. They posted an updated bios the day before. Didn't fix it. Boy, was it ever hot. But, the shutdown seems intentional. To prevent any damage to the hardware. Tried the vacuum cleaner to the vent (heat sync) underneath. Reduced the frequency of shutdowns.
This fixed it. Made a tray for the laptop from a piece of plywood. Wider than a laptop for a mousepad. But, at the end away from you, the back; a strip of wood to elevate the back and allow air in. Also, cut a hole in the plywood under the heat sync and fan. I put another strip of wood across the back underneath. Its nice to have a little elevation on the keyboard and you only have to slope the monitor to see it.
Good Luck all. I was never any good at micro screws and angel hair wires. And I have been a tech in a computer shop.

A quick and easy solution to elevate the notebook is to use 2 large door stoppers, cheap and works great!

Where do I begin??? :) First, I must wonder why there are so many questions about problems with Toshiba laptops in this topic that have absolutely nothing to do with shutting down, when this topic is clearly lableled "Toshiba Satellite Shutdown"....

Anyhow, I am an ex-laptop engineer that now repairs laptops, and I can tell you all(as stated here before by others) that forced-air cooling eventually causes blocked cooling passages on all electronic equipment, not just "Toshiba" laptops. It can even happen after only a few months, if the fan runs alot and there is alot of dust and/or hair in the environment. Cleaning the collected debris from the heatsink should correct the problem, and should be considered occasional system maintenance by people that use their laptop in dusty environments. Other people that only use their laptops in dust and hair-free environments would likely never have these problems.

Disassembling and re-assembling a laptop is very easy, if you are good at surgery and can remember where every screw goes, or at least are good at labeling each screw type and location. If you are not good at surgery, then do not attempt to disassemble a laptop, have a friend with the proper skills do it for you.

I wouldn't expect Toshiba to go around telling everyone that their laptop isn't working because the heat sink is clogged, because many people would blame Toshiba(just because they already knew that dust can collect on heatsinks) and would improperly expect Toshiba to fix this for them for free, when Toshiba is not the one responsible for clogging up the heatsinks of their customers laptops. Any reputable community repair shop would clean your fan for you in about 30 minutes, and shouldn't charge more than about $50US for doing so. Any shop that charges more or tells you that you need a new motherboard should not be considered reputable.

As far as quality goes, I can tell you that Toshiba makes some of the best laptops that money can buy, but before anyone shakes an angry fist at Toshiba, make sure that you are actually using a REAL Toshiba laptop(identified on older models by their 15 Volt AC adapter) as opposed to a Toshiba labeled laptop that is actually made by Compal(identified by a 19 Volt AC adapter). Even Compal laptops are very good, and I still own and use my old 1905 Compal built Toshiba, but also enjoy even more my newer Toshiba built 5205-S119. Every manufacturer of laptops will create units that don't work properly on occasion, it is just the nature of the beast, and is a fact of life. A bad experience with a particular model can usually be resolved by simply getting a different model of the same brand, usually not necessitating a switch of brands and string of four-letter words. You can bet that any fault done by one manufacturer(such as not admitting a known problem) has also been done by every other manufacturer, too, so if you scream at one, scream at them all.....

My Toshiba Satellite has a similar problem, but even worse. The battery itself cannot charge anymore because of a malfunctioning of the ac adaptor connection. My dad says he can fix it if we can disassemble it. I've removed all the screws but am afraid to do anything else. I might crack or break the shell. Anyone mind helping me out on how to disassemple one correctly? Maybe with use of pictures or what not?

I know getting this repaired at a store would be very expensive, and I'm a starving student, so I'd rather have my dad try to fix it for free.

Thanks!

Ryan, you are probably missing the screws underneath the translucent plastic cover above the keyboard, which is released by a sliding a retaining rod that can be slid by inserting a thin object between the edge of the keyboard and the translucent panel above it, and moving the object sideways until the plastic piece releases. There are then more screws to remove underneath....

Hitek

EDIT: Be sure to read my warning in the post above about disassembling your laptop. You will have to completely remove the motherboard to repair the socket, so make sure that you remember exactly where everything goes. As a general rule, If you can't figure out how to get it apart, then you probably should not be taking the laptop apart in the first place.... :)

It is interesting to note, that heat problems are generally more prevalent when a manufacturer is using the newest, fastest chip available at the time in a newly designed laptop, as if they have to get accustomed to the quirks of cooling the new chip. After designing the second or third different laptop model using the same processor, they seem to get things sorted out... :) Maybe it's not a good idea to buy a laptop with the newest variety processor, and instead buy a laptop that not the manufacturer's first attempt at using a given chip??? Anyhow, DVD and CD burners get very hot all on their own, without needing a nearby hot-running processor to help them get hot. Place that hot burner drive in the same small space with a CPU whose hieatsink may be slightly clogged, and things can get really hot, really fast. I don't know how updating firmware, drivers, or software is going to make your hardware run cooler, unless the new versions just change default settings to slow the devices down, making them run cooler. It it in this spirit that I will suggest to everyone having overheating problems to open your power management settings, and make sure that your processor is not always set to run at full speed. This makes your laptop's fan run much more often than normally needed, making dust and debris collect even faster. The more dust and debris that the heat-sink collects, the faster the fan has to spin to cool it, making dust collect exponentially faster again, until the heatsink is quickly clogged..... I have removed complete blockage from the heatsink of every forced-air cooled laptop that I have owned, which has been many, and every one ran faster and cooler after removing the standard build-up....

Help
I have had nothingbut troubles ever since i bought a laptop 2 years ago. My first laptop was a Hp it died within the first year. they sent it away and they couldnt fix the issue
Since i had warrenty they showed me this toshiba A70 .. said it was a great computer and exchanged it. Well now every time i try to transfer a movie to a dvd The computer completely shuts down. Its been happening even when im on line surfing the net.
Not only this But i also can barely hear the sound coming from the speakers. The volume level is utterly low... I have the settings set to full but still hardly any volume.
So between the shut downs and the volume It is starting to aggravate me.
Is it because its a toshiba? I cant believe they make computers like this.

Hi all, i bought aToiba A70 oow laptop around 4 months ago, and last night i turned it off, realising i had to turn the machine back on, i pressed the power button, it glowed blue, the fans started. But before it got any futher ie. the bios screen, the fans turned off and all went quiet, the LED light stayed on and the screen remained blank. I held the power button for a few seconds to turn it off, and then on again, the same thing happened, after slapping the desk a bit (not wanting to wreck the LCD screen) i tried again, and again, and again... after what seemed about 40 times it flashed and turned on OMG yes! BUT... ...upon reaching the password screen, everything froze, the mouse, EVERYTHING! I yelled and turned it off. grr. after that it has not turned on. I went and talked to the supplier and they gave me the toshiba number, which i rang and they put me onto a group named Future, im seeing them this arvo. But after reading this forum im guessing it has something to do with the heat sync, and/or, static electricity.

If anyone can help it would be greatly appreciated, Thanks in advance.

I bought Toshiba A70 one month ago. Now I have a memory disk San Disk which when is pluged in to the notebook makes it restart. I also tried with a digital camera - the same thing. Oce I get to the removable media my notebook just restarts (prior showing some blue screen with white letters for half sec). My San Disk memory stick works fine on other computers with win98 and winXP.
One more thing: when I format the memory disk on the notebook it leave about 80 Mb free space only (memory stick has 256 mb). Formatting on other compauters works fine.
Anybody know why my Toshiba restarts when using removable media through USB2?
