Toshiba C55 Not Booting Fan Speeds Up and Down
"My Toshiba laptop suddenly shuts down by itself without any warning. Sometimes it works small for hours, sometimes it shuts down feather in 10-15 transactions." This complaint we hear from our customers over and once more. About 15-20% of all Toshiba laptops we beget 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:
- The keyboard and the bottom of your laptop computer are very live when the laptop is workings.
- The CPU fans are functioning all the clip at utmost rotation belt along and operate much louder than before.
- The laptop computer suddenly shuts down by itself without warning. When IT just started, the laptop computer was shutting down afterward 1-2 hours you said it it shuts down after 5-10 proceedings of operation.
- The laptop computer whole shebang precise when it runs bone-idle, but shuts down as soon atomic number 3 you start using any memory demanding applications (DVD player, image editing software, telecasting editing software, etc.).
Solution:
If the CPU heatsink is not clogged with dust and lint completely, you can use canned flying and just blow information technology inside the laptop computer through with the openings happening the bottom and happening 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.
- Open the laptop computer case, so you tail end access the Central processor fan and the heatsink. In some cases you can approach the heatsink through the fasten on the bottom of the laptop. Sometimes you hold to open the laptop case wholly the way down.
- Carefully disconnect the fan cables connected the scheme board and remove the fan. If the fan makes unusual sound when it spins (grinding sound), I would recommend to replace the fan.
- Clean the fan and the heatsink with compressed air.
- I would also commend removing hoary thermal dirt from the CPU and applying new grease for better heat conduction.
UPDATE: I just acceptable a nice hint from Megacycle N'Colorado. I imagine it could be useful for all of you with guys:
I distinct to use a browse vac to suck the dust tabu and information technology worked. I tested it by letting the machine bleed all night and it worked. It's been a few weeks now and I'm grateful I did it. I was ready to take the machine apart, now I'm glad I didn't. I'd suggest you use a heavy duty shop vac to clean out the lover and estrus sinks first.
I agree. Test to fix the problem without taking the laptop computer apart first but I would recommend using a powerful air compressor as an alternative of a vacuum cleaner.
If your laptop is still under warranty, you can admit it to any Toshiba Authorize Service Provider and fix the job at nary charge to you.
