Question about Toshiba Satellite M45-S169 Notebook

1 Answer

Shutting down without warning

The problem persists. It is not a overheating problem nor a motherboard/cpu. all that checks out. we exchanged power supply, but it still just shuts down. Was thinking about wiping the hd, repartition and reinstall, not sure if that would solve the prob. Definitely need info/input. Hubby to leave for deployment in a few days.

Shutting down this way is usually loose or ill fitted hd,sometimes mem or conflicting software.
take out hd refit making sure housed properly.start up pc and see how it goes.
check mem.take them /it out of housing check for dust.. refit.
some tech's suggest taking mem out and swapping them around ..this has no impact the mere fact thet you remove clean and refit is all thats required.

NEW HP Spectre 13T-3000, 13.3" Touch will not run with the battery and shuts down randomly


you can use the unit without the battery. Remove the battery, plug in the charger/power supply and turn on the unit and wait for the result. if the problem persist?..... maybe the fault is in CPU fan. check the fan...overheating the processor. Cleaning the heat sync and reapplying silicon compound on CPU's can cure the problem.

The system shuts down suddenly after every 45 minutes or so without any warning and there are horizontal lines at the bottom of the screen where the selection bar is located.


Overheating problem. What is happening is that the laptop is getting too hot and the graphics chip is suffering as a result, which is why you are getting the display problems. if you persist in using it, the chip will eventually die on you.

Solution:

You need to dismantle the laptop until you can access the motherboard heatsink and fan assembly
You also need to have some thermal grease to hand.

Remove the heatsink and fan, clean out the dust and lint from the fan housing, the heatsink and the cooling grille. Clean the top of the cpu and apply clean new grease (about a 2mm ball of it will do). Also clean the heatsink pad that touched the cpu.

Check the thermal pad (if present) that sits on the graphics chip is not damaged and make sure it is in place before refitting the heatsink and fan assembly.

Rebuild the laptop (you can get some good instructions off google if you look for your model)

Lenovo T61 keeps shutting down for no reason. Repair shop took out fan and checked it, works fine. They also blew out dust from vents. Problem still there. I installed a CPU temp utility pgm and shows temp...


Automatic shutdown is always cause of overheating, busted heatsink/ fan/motherboard. if the fan and heatsink wasnt replaced yet though they check it fine i would still recommend replacing it. if the problem persists a mainboard replacement would be the last part needs to be replaced.

“My Toshiba laptop suddenly shuts down by itself without any warning. Sometimes it works fine for hours, sometimes it shuts down in 10-15 minutes.” This complaint we hear from our customers over and over again. About 15-20% of all Toshiba laptops we get for repair, suffer from an overheating problem. Yep, OVERHEATING!
This is one of the most common problems with Toshiba laptops we deal with.
Indications of laptop overheating problem:
  1. The keyboard and the bottom of your laptop are very hot when the laptop is working.
  2. The CPU fans are working all the time at maximum rotation speed and operate much louder than before.
  3. The laptop suddenly shuts down by itself without warning. When it just started, the laptop was shutting down after 1-2 hours and how it shuts down after 5-10 minutes of operation.
  4. The laptop works fine when it runs idle, but shuts down as soon as you start using any memory demanding applications (DVD player, image editing software, video editing software, etc.).

Solution:
If the CPU heatsink is not clogged with dust and lint completely, you can use canned air and just blow it inside the laptop through the openings on the bottom and on the sides. It’s nice as a precaution measure, but it might not work if your laptop already has a problem and the heatsink is completely clogged.
  1. Open the laptop case, so you can access the CPU fan and the heatsink. In some cases you can access the heatsink through the latch on the bottom of the laptop. Sometimes (for example Toshiba Satellite A70/A75) you have to open the laptop case all the way down.
  2. Carefully disconnect the fan cables on the system board and remove the fan. If the fan makes unusual sound when it spins (grinding sound), I would recommend to replace the fan.
  3. Clean the fan and the heatsink with compressed air.
  4. I would also recommend removing old thermal grease from the CPU and applying new grease for better heat conductivity.

5175 acer aspire auto shuts down as if it short-circuits....


it is possible that it is overheating - check to see that the fan is working correctly and if it does, try to put something below the laptop so it will have some air flowing below it

My laptop swithces off itself every 40 minutes


This is typical of a overheating (thermal shut down) CPU problem.
When the CPU overheats and shuts down, it won't bootup again until the CPU cools down. If this is not fixed then the CPU will fail.
This problem is caused by either a faulty fan or the fan and heat assembly is clogged with dust.
Check the fan to see if it spins freely, replace if faulty and clean the dust off the fan and heatsink assembly.
Also apply fresh thermal paste to the heatsink/CPU.

Dell Latitude D610 Shuts off with no warning...


the problem is not the battery; what has happened is the coolant paste that pulls the heat away from the cpu (main) chip to the fan has dried up. you must remove the fan/heat exchanger off the motherboard and, put new paste on the chips that the heat exchanger sits on
radio shack sells the paste

Dell latitude c640 laptop


This could be caused by a number of thing, bad battery, bad power supply, bad memory chip, bad processor, and a bad component on the motherboard. Start by checking the output of the power supply with an ohm meter. The output rating will be on the power supply or you can go by the input in the machine. Then try starting without the battery. Then remove the memory and try with one chip then the other. At this point, if the problem persists, you will need to take it for a professional diagnosis. They will be able to test the processor and motherboard to find the exact problem component, and tell you whether it's replaceable.
