Sony :: 2010 F Series Makes Buzzing Noise

Jan 15, 2010

I just purchased the new 16" F Series. Right out of the box, the unit makes a slight buzzing noise on the right side.

It starts after the unit has booted. It tends to happen when the machine is idle. It's the same if the battery is in or out.

Dell :: My Latitude E4200 Starts To Make A Buzzing Noise

Jan 1, 2010

Recently my laptop starts to make a high frequency whining noise, almost constantly and rarely stopped.

I tried to locate the component which the noise was originated from, I can only figure out it's somewhere below the memory module, but there is no moving component there, so my biggest suspect is the fan, because if I put my ear to the back of the laptop, except the whining I also heard very minor "clicking" noise.

Another weird thing is, this noise only starts after Windows is loaded, not in BIOS or during booting, although the fan was running at those times.

Dell Latitude E4200 :: Backlit Keyboard Noise - Slight Buzzing

May 4, 2010

I just picked up a e4200 with backlit keyboard and whenever the back light is turned on there is a noise (slight buzzing or hum) that can be heard. As soon as the back light turns off the sound goes away. It's kind of bugging me because you wouldn't think that the back light would add to the decibel level of the laptop..

Sony :: FW Series Hi-Color Nits, Screen Quality- Fan Noise

Mar 20, 2009

The FW has a CCFL screen even if it's hi-color, full hd, right?

Notebook check says it's 357 nits! Is that really the case, b/c I thought the Sony Z would have the best screen and it was something like 280 nits. 357 is just ridiculously bright and the brightest that I've ever heard of.

1920x1080 hi-color screen vs the Sony Z's screen?

Is it audible when surfing the web, etc and not under load?

Lenovo P/Y/Z Series :: IdeaPad Y510p Fan Buzzing

Dec 17, 2014

I bought my y510p brand new from Lenovo about 11 months ago. About 2 days ago, my fan suddenly started making a very loud buzzing/grinding noise. Prior to this, it was perfectly quiet. The fan makes this noise inconsistently, and at this point, leaving it on a flat surface keeps it quiet. However, any tilting or jostling of the laptop makes the fan start buzzing again. I have noticed that running the dust removal utility will stop the fan from buzzing, and this seems to be the only way to return it to producing a regular sound after it has started.
 
I really don't think my fan needs to be replaced, but I am unsure what is causing this problem. I have never dropped my laptop--and its spent almost its entire life on my desk. The only thing that's changed is I moved it after it had remained in the same spot for several weeks--because I am currently traveling.
 
The inconsistency of the noise and the newness of my computer tends to make me think the fan hasn't worn out yet.

Sony :: VAIO AW Screen's Buzzing!

Oct 25, 2009

I have Sony VAIO VGN-AW360J.
About two weeks ago I noticed something weird with the brightness regulation of the display. When I tried to change the brightness

(always set up to the maximum) to a lower degree using the keys (Fn F5) a high pitch noise can be heart coming from the screen (to be more exact -

from the lid of the laptop, below the VAIO logo), and it is very noticeable in a quieter environment. Continuing lowering the degrees of brightness would cause higher or less noise. The nosier setting is at 90% of brightness

Lenovo U/S Series :: U530 Loud Whirring Noise

Jul 16, 2014

I purchased the lenovo ideapad u530 about 6 months ago. Recently, there has been a loud whirring/buzzing noise coming from the laptop (possibly the fan?). It is most noticeable at the bottom near the vents. There seems to be no correlation between what I do on the laptop and the noise.

Lenovo P/Y/Z Series :: IdeaPad Z500 Brightness Can't Increase

Nov 24, 2012

I have a new z500 that I've downgraded to Windows 7 64bit. For the most part I have everything working. I accidentally hit the brightness + (yes, +) and it instantly dimmed the screen to where it is barely viewable. It seems that hitting that one key decreased the brightness to the minimum amount. I've rebooted, looked for a setting in the BIOS, hit the Brightness +/- and can't increase the brightness. It is interesting because the other hot keys work correctly. I've even upped the brightness in the Control Panel, but nothing seems to work. The screen is extremely dim whenever the machine is powered on (including the BIOS), not just in Windows. I tried a lot of intel chipset drivers, the available Intel HD 4000 drivers in Win8 and win7 too, but nothing working. How to up the brightness?

Lenovo B / G Series :: G500s - LCD Brightness Non Adjustable In Windows 7

Nov 11, 2013

I had lenovo g500s recently with windows8 64bit preloaded. I got bored from windows8 and downgraded to windows7 home premium 64bit (a difficult procedure by the way)....
 
Windows 7 worked very fine after installing the device drivers, except for the LCD brightness that doesnt respond to any fine adjustments...
 
In the main page of windows power management, as well as the keyboard hotkeys, the slider either goes to the maximum or minimum brightness (no stages in between though in windows 8 there were > 6 stages)....

In the advanced settings screen, as far as i adjust brightness (for example to 50% on battery, 70% plugged in) this doesnt lead to any change in the brightness practically....

Lenovo P400 P/Y/Z Series :: Touch Screen Brightness Won't Adjust

Apr 13, 2013

I used my brightness down button once and now it won't go back up. I can't adjust the settings at all, despite the graphic on the screen showing me the meter going up and down. I've checked all drivers, tried uninstalling and reinstalling lenovo energy management, and I've still got nothing. I've stopped short of a factory reset because that's super annoying having set everything up and then a couple weeks after purchase have to do it again.

Lenovo U/S Series :: Can't Change Screen Brightness Anymore - U410

Jun 27, 2014

For some reason I can't change my screen brightness anymore. I've already tried a HD 4000 driver rollback to version 9.17.10.3223 and I also disabled "adaptive screen brightness" at the power management. For some reason I can change the brightness by using the "microsoft basic display adapter" driver instead of the HD 4000 but that isn't a real solution.

Lenovo G505 B / G Series :: Screen Brightness Not Adjusting On Laptop

Jun 16, 2014

My lenovo G505 recently had to be reformated because there was a blue screen that came up one day that said there was problem with my PC and the error was critical_service_error, something like that. So my dad had to reinstall windows 8 for me using a cd he had that didn't come with the computer I don't believe. So now for some reason my screen brightness isn't adjusting and it's driving me crazy! It's staying on full brightness which I hate! I tried changing it from the personalization screen and nothing happens.

Lenovo P/Y/Z Series :: Screen Brightness Flickering When Z570 Plugged In

Jan 5, 2014

When plugged into the adapter my Levovo Z570 screen flickers between bright and dark when on certain webpages or doing certain tasks. I have changed the battery and this makes no difference. This doesnt happen when on battery power.
 
Note that the brightness is flicking between the battery brightness setting and plugged in brightness setting. So if there is a large difference between the two the flickering is very noticable and distracting. If I make the battery brightness the same as the plugged in brightness the flickering doesnt happen.

Lenovo IdeaPad Z570 15.6 inch Laptop - Gunmetal (Intel Core i7 2670QM, RAM 8GB, HDD 750GB, NVIDIA GT520M 1GB, Blu ray, WLAN, BT, Webcam, Windows 7 Home Premium 64 Bit
