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..

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.
I called dell part department today and the rep told me e4200 backlit keyboard cost 180USD
there are no backlit keyboard on ebay for a while. I usually checks it once a week since April.
anyone have an idea to get a affordable backlit keyboard for e4200?

Latitude 6430u: Is there a setting to keep the backlit keyboard ON?
Mine times out @ 10sec.
Original Win 8 Pro, then updated to 8.1 Pro, the back lit keyboard works OK. However since I refreshed the system due to the hangs up problem at start up, the back lit key board stops working. Re-updated the OS back to 8.1 Pro again still not solve the issue.Does the backlit key board need special driver ? The device manager shows the keyboard as standard PS2
View 7 Replies View RelatedI was recently given a Latitude E6530 and I wish to upgrade the standard keyboard to a backlit one after coming from a MacBook Air. I was wondering, does E6530 (or it's similar models) requires an additional cable to power the backlight or does it just feed off the single cable? I've scoured YouTube and Google to try find out if an extra cable is required for this model however wasn't able to.

View 2 Replies View RelatedWhen I am burning a cd or dvd, the drive makes a really loud buzzing noise that sounds like its coming from some sort of vibration.
If I push the drive in and up just a bit while this happens, the vibrations stop and the noise goes away.
It's recently been making noises, it happened before and I thought it was not a big deal. Until now, it keeps making noises and then freezes the whole laptop. I had to press power button and waited like 2 or 3 minutes for it to restart. It always happened while i'm playing online games then it freezes... i don't know how to check the fan or temperature of my lap top all i know is when i touch it sometimes its hot...my laptop is dell xps 15 (L502X).

I am seriously considering purchasing this laptop. I have read reviews concerning a constant high pitched "buzzing" noise on this model.
View 4 Replies View RelatedI 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.
I have been see-sawing between the Sony Z and the E4200 (two very different machines) but being a Dell customer for the past decade, and having access to Premier and EPP, tipped the decision in favor of the the smallest E in the new Dell portfolio.
I thought I would start this thread as a 'catch all' place for all the folks who are ordering the new E4200. I have been looking for info on the E4200 in particular but there isn't much to be found though a few folks have indeed received their E4300s.
There seems to be some disappointment with the E4300. I am holding out until the backlit keyboard as well Latitude ON (hardware-based) are widely available. It does seem that some of the kinks still need to be ironed out from the lilliputian E-class Dells. Here's an early review that pretty much sums up the disappointment that some new owners are feeling:

There are two different LED Panels used for E4200.
Toshiba is not a good one, which has some bleeding issue.
Samsung is the best, which is soft.
You can figure out which panel you own on your E4200 via looking at the bottom of LED panel (Golden color means that you have a Toshiba one, and Silver one will be Samsung. Toshiba one also shows a lot of small bulbs at the edge, bad, bad...
Windows 7 seems to be running fine on the Dell Latitude E4200 other than the fact that the Ambient Light Sensor is not working,
did anybody find a fix for this, I know you can find the Windows 7 driver for the Dell Latitude E4200, but still same issue,
A few days ago a couple of keys from my dell e4200 (non-backlit keyboard) were broken, and I think is timely to upgrade (myself) to backlit keyboard. I was wondering if anyone has done the same and if it's worth.
Another issue is how to activate the lights on the keyboard, because i use linux, do you believe it is a problem
I am on to my 2nd Latitude e4200 now ...
the first one had the fan come on straight away at the start and then never turn off. Regardless of what temperatures the ACPI and cores were running at.
it was running bios A03 and we upgraded it to A04 and that didn't fix it. We think the thermistor was buggered so we replaced that but then the Dell service guy basically couldn't remember how to put it back together and buggered it so it wouldn't boot!..........................................
I think the E4200 is a great machine, and I can probably get one cheap off Dell Outlet. My only real concern here is hard drive capacity. The standard options of 64GB or 128GB SSD aren't going to cut it for me...
I'd want to have at least a 256GB SSD or one of the Toshiba 250GB 5400RPM 1.8" drives.
I know that the E4200 has a 1.8" hard drive slot, so a standard 2.5" notebook hard drive will not work at all.
But its 1.8" slot should mean that regular 1.8" hard drives should work in it, no? Surely the computer can use either a 1.8" SSD drive or 1.8" hard drive
Two days after my warranty expired, both USB ports on my E4200 and the fingerprint reader stopped responding. The USB on the docking station work fine.
I have since tried to update the bios and uninstalled the USBs in Device Manager. All to no avail.
When I plug a stick into the USB port, it lights up (i.e., some power to the port), but the computer does not see anything plugged in.
2 days ago I was given a new work laptop - the E7440 (its brand new).
Straight away I noticed some loud buzzing noises which a fellow colleague said was the fan. It's quite annoying. I soon noticed however when my laptop was idle these noises would stop, and when I clicked they would start again. Whenever I ask the Laptop to do anything these noises start up, and considering im active on the machine all day.
There are high pitched, buzzing noises. And as mentioned are aligned to when the laptop is processing something. They also make sounds when I scroll the mouse for example.
I've recently taken delivery of an E7240 with the FHD touch screen option. I am generally quite impressed with the laptop except for one thing, the touch screen buzzes. The sound is similar to a hard disk working, a bit random .. not a constant noise. The sound will immediately stop when I put a finger on the screen though which makes me think it's related to the touch screen itself.
Rebooting etc. makes no difference... shaking the laptop, smacking it (gently) etc. has no affect.....
I realise these laptops are new so perhaps there isn't much experience out there...
I have an older e4200 (roughly late 2008) and want to let my child use it. Before I hand it down, I want to completely clean the hard drive and start from a "brand new" perfectly clean hard drive with Windows and all the appropriate drivers installed. How do I accomplish this?
View 7 Replies View RelatedI got a Dell Latitude E4200 with a Samsung SSD PB22-JS3 TM 64GB drive. Does anyone know if its firmware can be upgraded to support TRIM in Windows 7? Current
firmware version is VBM19D1Q. Seems like the version that support TRIM is VBM19C1Q. Doesnt that seem like a downgrade? I've had my notebook since October 2009 so I dont think it has TRIM support from the factory.
Firmware location I think is here: http://www.samsung.com/global/busine.../business.html
I installed Windows 7 64 bit on a Dell E4200.I had two yellow exclamation points in device manager for unknown devices.
PCI Serial Port
PCI Simple Communications
I went to Dell support site and to the drivers and downloads page for my Service Tag.Under the Chipset section there is an Intel driver for AMT HECI. Installing that driver solved the PCI Simple Communications item.
Also under Chipset there is an Intel driver AMT SOL. I installed that driver but the PCI Serial Port was still showing Unknown with the Yellow..In my case I had to then manually Update the driver as follows:
Open Device Manager > right click on PCI Serial Port and choose Update driver > choose Browse my computer and browse to the driver folder for the AMT SOL just created when you downloaded and installed the driver mentioned above. Location for me is C:DellDriversR279202.
I’m testing some E4200s (with SED SSDs and regular SSDs) and have run into a possible bug with the HDD password “bypass” option in the BIOS. The “bypass” option in BIOS allows you to specify if the HDD password needs to be entered during warm boots (restarts), standby, etc. I’ve set it to “disable”, which means that the HDD password must always be entered (even for restarts). However, the E4200 does *not* prompt for the HDD password during warm boots (restarts). It correctly prompts for the HDD password during cold boots and standby/hibernate only. I’ve tried upgrading the BIOS to the latest version (A13 to A20), but that didn’t work.
At this point I think it's a bug in the BIOS. I've tried this with different e4200 laptops and different drives (regular SSDs, and self-encrypting SSDs).
