Dell Precision M3800 :: Power On Sometimes Works

Mar 28, 2014

Shouldn't I be able to simply press and release the power button to power on the laptop for a cold boot?

I'm not sure if I'm powering on my M3800 properly or if it's a problem.

All scenarios are after the laptop had been completely shut down and powered cable attached.

(1) Just pressing and releasing the power key powers it up sometimes
(2) When 1 doesn't work, sometimes pressing and holding the power key (for ? secs) will power it up
(3) When neither 1 nor 2 will work, sometimes double-pressing the power key will power it up

The times it doesn't power up, the power button lights, keyboard lights and goes off, then power light goes off.

It eventually always powers up (so far) but would like to make sure it's not a hardware problem.

Dell Precision M3800 :: BIOS Does Not Recognize Samsung MSata

Apr 6, 2014

I'm trying to install an extra Samsung 840 evo mSata in my new m3800 but the BIOS does not recognize the disc. I tried 2 840 msata both with same result not recognized. 

Changed several settings in BIOS:

- disabled Intel Smart Technology- SATA operations to AHCI- Secure boot disabled- load legacy option enabled

Does the Samsung mSata is supported in an m3800?

I'm on windows 8.1.

How do I disable clicking on the touch pad? So that when I just tap it without depressing the button it  doesn't click.

Dell Precision M3800 :: Strange Static Noise When SSD Is Accessed

Jan 12, 2015

I have a new M3800 Precision Workstation that is making a really annoying sound when it is plugged into power and when the SSD is being accessed, mostly when it is being accessed randomly such as search, VM running, or just random file access test from benchmarking software. The pitch of the scratchy sound varies with screen brightness.

I've made a video of it here [View:youtu.be/jbEkRDrPTdA:550:0]

Dell Precision M3800 :: Mouse Pointer Will Jump Over Text Boxes

Dec 11, 2014

Got an issue with new Dell Precision M3800 + HD 3100 Dock.  My issue with with the mouse pointer.  After using the laptop for 2-3 hours, I'm getting an issue in which the mouse pointer will jump over text boxes (does this in any browser, when trying to click in the formula field in excel, even when clicking in this dialog box to type).  Basically what's happening is the mouse pointer thinks the text box is higher than it really is. 

So, if I go up to the address bar from under, as I pass over the bar, the arrow changes to a text cursor, but jumps above the actual address bar...if I click, I can type in the bar.  If I keep going, eventually the arrow pointer will come back, but it will jump back down to the actual top of the address bar.  In the case of typing in this box for posting, in order to get the cursor here " ", I have to click where I have the star above (in the word "can"). 

It just seems like something is very out of sync, and I'm thinking it has to do with the graphics card or some resolution setting.  I have an Acer V246HL set to 1920x1080 + a Viewsonic VA2746M set to 1920x1080 as well.  Only fix I've found so far is to reboot.  I've messed around with the resolution numerous times.  This issue only appears when connecting multiple monitors (which is a necessity).  I did not have this issue w/ my previous laptop, which leads me to think this is not a monitor issue either

Assuming the battery had died, I plugged it to the charger, pressed the power button, and nothing happened.I got up to assure that is was firmly connected to the wall outlet, And it was.So my laptop has shut-off and will not power on at all.It's acting as if it's not receiving power at all.The green light on the Dell charger is green until plugged into the laptop. It goes out immediately.The battery is fully charged for the battery indicator shows so.What's going on?Is my CPU bad?

Acer Aspire V3-772g :: Won't Boot - Power Works / Lights Work

Dec 10, 2014

I have an Acer Aspire V3-772g, a relatively new laptop (8 months old), which randomly decided to stop booting.

Windows 8.1Core i7 2.2ghznVidia GTX 760m8gig's of ram (2x4gb)7200 RPM SATA

Was playing a game just fine. Shut down as normal, went to work, came home 8 hours later, attempted to boot - nothing.

Exact problem: Hit power button, power button comes on. Light next to the lightbulb (power light?) Comes on, stays solid. Charging stays solid orange/blue.

HDD light? Flickers. Screen flickers a dark grey color that may be the very initial part of a startup. No acer logo.The screen and HDD light flicker in synchronisation, at the same exact time. You can hear the fans fire up, and the HDD spin up. Screen just flickers about once per second (it's very faint.)

--Heres what I've tried---

-Removing power cord/battery, holding button for 60 seconds 3 times, plugging back in and powering up.
- Almost every varation of that, I have attempted.
-Inserting a new harddrive. Same result.
-Plugging in an external monitor. (Tried VGA and HDMI)
- Power does not transfer to external monitors. Screen still flickers on laptop, no change in behavior.
-Removed 1 stick of RAM - No **BUT** behavior changes slightly. Flickering of screen and HD light reduced to about once every 45 seconds rather than once every second.
-Removed both sticks of RAM - no flickering, no HDD light flickering. Pure black screen.
-Rotated the sticks of RAM - No change.

Also interestingly, with everything normal, if I hold Fn+Esc, the computer will do a new startup process (Screen still black), then after about 20 seconds goes into the normal screen flickering/HDD indicator flickering. Different behavior, slightly.

Dell :: Precision M6400 : Is It Possible To Put The GPU Into A Low Power Mode

Apr 11, 2009

Precision M6400 : Is it possible to put the GPU (2700M) into a low power mode ?

Often, when I'm on battery, I do low GPu work, like text editing and compilation, or giving presentations. Also I use XP 64 bit; all low GPU work.

Can I downclock the GPU or undervolt it or do something to conserve energy ?

Dell Precision M4800 :: Slow Performance Without Proper Power Adapter After BIOS A8 Update?

Sep 19, 2014

I recently updated my Dell m4800 to BIOS A8 with Windows 7 64. I had been using a collection of older power adapters from my previous Dell m4400 without any issues. After the update, wow. A huge performance hit if I do not have the 19.5 volt and 9.23 amp adapter connected.

The m4400 power adapter is 19.5 volt and 6.7 amp. Pretty close right? Not any more.

I do have it connected to a Dell docking station almost all the time. Just checked. They are both 6.7 amp.

What changed in BIOS A8 and what the deal is with the performance? Looks like I need to request a new docking station, but I'm not sure IT will believe my story.

I found several mentions of Ending Process in Safe Mode, but this did not work. I tried to format the drive and reinstall windows, but it wont erase the partition with XP on it

Dell :: Microsoft Works 9 Crashes On My XPS 1530...

Jan 5, 2009

I try and paste large amounts of text (several pages worth) into a new word document, and it crashes, saying problem was with DEP security.

I try and turn that off for works and it won't let me.

I talked w/Dell tech support and they had said to uninstall and reinstall. Which didn't work.

Which they then advised to call a different department at Dell, something more associated with software issues...

Dell :: M1530 Dropped, UNMOUNTABLE_BOOT_VOLUME, But Works In Other PC

Feb 4, 2009

Looking for some help here and don't know where to turn.

My M1530 fell, it worked for a while, but then it crashed. On Vista startup, it will bluescreen with either an UNMOUNTABLE_BOOT_VOLUME or that IRQL_IS_LESS_THAN_OR_EQUAL (something like that anyway) error.

Dell's diagnostic tests gave an error on the Hard Drive DST Short Test of 2000-0142. Dell says that means a broken hard drive and they are sending a replacement.

I tried putting the M1530's hard drive into a Latitude D620, and it booted! Slowly, but it booted. I was able to see the drive and use it for a good 12 hours before I shut it down.

Dell :: Inspiron 1420 Only Works On External Monitor

Nov 2, 2009

i have an inspiron 1420, and want to bring it around school, i usually use it as a desktop at home using an external monitor(FN + F8), for some reason my laptop only works when plugged with a monitor, the laptop monitor is blank but you can see light at least, but no images whatsoever. I got it to work after reformatting the second time but not the 3rd 4th or 5th time.

I've noticed something strange though when formatting with xp, the letters were both gray and red, and when it gets to the page with the estimation(usually about 30 minutes) the picture quality was crap like 4bit.

I've noticed that when i successfully got the laptop monitor working the picture quality ran at a full 32bit

Dell :: M1330 (Windows 7): Two Audio Outputs, Only One Works

Dec 11, 2009

I recently upgraded my M1330 from Vista Home Premium to Windows 7 Professional, and I've lost the ability to use both audio outputs at the same time.

For example, on the front of my laptop, there are two audio outputs, so that two people can listen to something at the same time.

However, after going to Windows 7, I've lost that ability. Both of the outputs work, but you cannot use 2 headphones simultaneously.

I used the SigmaTelHD Vista drivers and no luck.
