Question about Sony VAIO VGN-N250E/B Notebook

1 Answer

The laptop seems to work completely fine often for several hours sometimes only for about 20 minutes and then with no warning it just shuts down. Have reinstalled OS and am using fan tray to guard against over-heating. Event viewer reporting no errors. Guessing it could be RAM but it has passed diagnostic testing, and seems too infrequent. Running (sadly)Vista Home Premium. Does anyone know of any common faults with this model that could be causing this problem? Thanks.

Identical Problem here, I Managed to make it do it much less frequently by placing on a flat hard, surface and only moving it once in a while, if you listen carefully most people who have this problem hear the fans go a little faster for a second before it shuts down, it has been reported to be solved by buying a new charger that is from the same brand as your original

Projector shut down


happened to me something similar to what reported, only the small fan sometimes went off within minutes and sometimes seemed to work for hours
The room temperature was around 20 degrees, so the problem was software or hardware, but on the internet I did not find other people with this problem or fix
I did not update the firmware for the loss of the warranty, which I am thinking of claim

Fix OVERHEATING Notebook


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 A135) 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.

Toshiba A205 laptop charges fine, but freezes when adapter is plugged in.


Identification
  • Computer shops say that up to 20 percent of Toshiba laptops brought in for repair have issues with overheating. Symptoms may be as simple as the keyboard and bottom of the laptop being very hot while the computer is working, or the fans running at maximum rotation while the system becomes very slow for several minutes at a time. More inconvenient issues are common, such as the system completely seizing up and having to be "killed" with the battery pulled out, or the computer may shut down all by itself with no warning. Sometimes the laptop works fine until the user starts any significant memory-demanding applications, like photo editing software, several Internet windows being open at the same time, or an Internet video stream.
Significance
  • A common problem with the Toshiba laptop is that dust becomes clogged between the cooling fan and the heatsink, a device which lowers the temperature by dissipating heat into the surrounding air. Now heat produced by the processor is trapped inside the laptop, and the fan cannot blow it out.

E-machines E-527-2537 laptop Windows 7. when I turn it on the "starting windows" screen comes on then the screen turns black showing on the mouse pointer. Can you help?


Allow it to boot - sometime it takes several minutes. An unfinished process is possibly trying to complete because it was interrupted when it was shut down during the last session - please be patient. If it takes more than an hour to complete, then there might be a valid problem. Otherwise, wait.

Toshiba p205-s6347 notebook pc shuts down without warning


Your laptop is probably overheating due to an obstructed airflow path or a failed fan. Get some canned air and thoroughly blow out any dust and debris that may be blocking airflow. Sometimes the heatsink cooling fins get matted over with fibers and a lint ball will form in the fan-cage obstructing the fan rotation. If this happens it is often necessary to remove it with tweezers which may require some dissassembly of the notebook.

Good luck!
