Inspiron 3650 - Disable USB boot

$
0
0

Hello,


We use Inspiron 3650 at work. Some of the users are developpers, and aware of techniques to get admin rights on the PC.


So to block them, I want to block USB and CD booting (the last one had booted on his USB key to replace the virtual keyboard of Windows with cmd... The trick is, when you run accessibility tools from login screen, they are run as administrator, so he had modified his account to become an administrator...)


I can't find a way to disable USB booting, and I can't use "secure boot" as the desktops are migrated to Debian 8, which don't provides a signed UEFI (and it would be useless as the UEFI provided with Ubuntu IS signed... and so could be booted from USB)

Thanks in advance.


Runaway Fan, Thermal Shutdown but CPU Temps Normal

  • Found my T3500 had shut down. On start-up, got thermal shutdown warning. Once I logged into Windows 7, fan started running at max RPMs and soon shut itself down again.
  • Opened the case, cleaned the fan grates (there was a moderate amount of lint).
  • Left the case open, started up again, fan at max, but CPU temp app indicates normal (under 50C) temps. Does not shutdown, but did lock up eventually.
  • Started up again with fan disconnected. CPU temps normal, but locked up fairly quickly.

Seems like it's whatever is controlling the fans, not actual overheating. OTOH, still locking up with fans disconnected. Any suggestions? Thanks!

New Dell Computer Restarting by Itself

Hello,

I just purchased a new XPS 8900 desktop delivered on 5/25/2016 and is restarting itself.  No new hardware installed or program except World of Warcraft and Ventrilo.   Just really started using this machine late last week since I was really busy after it arrived. 

I research the web and it said it maybe PSU related issue.  It is under warranty but any idea why a new computer is restarting it self?

Thank you.

Yesterday I replaced the cdrw drive that came with the system with a liteon dvdrw drive, after booting into windows the first time no issues all drives show up and work in explorer, when I needed to restart the system and everytime now I get this error with the number of the drive changing each time. " drive 2 not found serial ata sata (0),(1),(2) . I have an optiplex 755 running bios version A22 unfortunately cannot get support from dell because the system is too old for them to allow me to pay for a contract with them, so how do I get rid of the message it always appears when it is doing pxe?

Connect S2716DG monitor to Alienware x51 r3

Hello,

what's the best way to connect S2716DG monitor to Alienware x51 r3 so that 

- G-Sync is functioning

- monitor works at 144Hz

I know G-Sync requires DP but x51 r3 doesn't have one so I can't use DP to DP cable.

I've tried HDMI to HDMI and HDMI to DVI-D cables - only 60Hz as a result.

usb ports not working

I logged onto dell.com today around 4:30 pm est, to try to fix an issue with my desk top which is only a couple of months old. I started a chat with Mohammed and he said that there would be no problem he would fix my issue which was my USB ports are not recognizing anything that is plugged into them. He ask for my phone number just in case we get disconnected he will call me. He remotes into my system and starts downloading Dell click to fix during the reboot we get disconnected, so I wait for him to contact me since I don’t have his contact info he has mine. Checking my phone and email nothing, this guy just downloaded something on my computer then disappears. So I get back on dell.com chat and get Venkata which it like we are starting over again I told her to look at my account gave her my service code and then here we go she give me a link to reconnect with her in case we get disconnected. 2hrs later she is searching for drivers I asked why it takes 2hrs for drivers, she then down loads chip set again updates bio’s nothing works so she deletes all of my drivers including access to internet which that is how we are communicating. Then the system restarts it a good hour on the restart to try to configure, so I click on the link that she told me to use to reconnect to her. I click on it and I get a message wrong access code. I am thinking she has my phone number she will call. Nothing. So I go back on line and try again to chat and I get a message chat not available at this time please call. So I call I explain my issue the guy apologies takes down my number again in case we get disconnected, he states that he will stay on the phone with me until a service tech retrieves the call, then the phone goes to a busy tone then hangs up. It is now 11:30 pm my issue has not been resolved and have not received any emails or call backs. This is a very bad experience I have been a long time dell customer, still looking at my first dell inspiron 9100 that I bought ages ago it a paperweight now. I have never had such a bad experience as I had today. Your outsourcing your tech support leaves no one accountable for their actions. My computer is down and I need it fixed ASAP.


Failed Hard Drive

We have a Dell XPS One 2720 that was setup at our Rescue Squad and is out of warranty. No problem, I can replace the hard drive but non on created system discs or backups and my look at Dell.com for drivers will not allow me to download the drives ahead of time so I can install them when I install the new drive and install Windows 10. It appears I may be able to order the system discs from Dell that I think will have Windows 8 Pro and hopefully the drivers/programs that would bring the system back to where it was when new.

Is there a way to download just the drivers that won't try to auto install or expand when downloaded? I want them on a USB memory stick ready to install after loading Windows 10. Suggestions welcomed. 

Thanks,

Steve

Wifi problems with Windows 10

I have a new Dell Inspiron 3650 i5 preloaded with Windows 10 (which I like).

However, following a recent update the Wifi keeps fading, disappearing all together and when the Desktop is turned on it regularly cannot connect at all and cannot find any Wifi networks to connect to at all. If I leave it running it eventually connects, but still fades in  and out making internet surfing erratic and email downloads lock out frequently. I know its not the Wifi router because I have my trusty old Dell Inspiron laptop with Windows 7 sitting on the desk next to the Desktop and its Wifi connection is absolutely fine and sound. I have tried unticking the power saver option as mentioned on some Windows 10 forums but it makes no difference. I also notice that my Google link no longer works (moved away from Edge as I couldn't stand the adverts / news feed. Can someone help me as W10 came with the system so Dell must be aware of the issue?

Survey request from TNS

Today I received a request from a company from TNS asking me to share my experience with Dell. The email references a case number 930607863. I have not had any interactions with Dell support recently, so I'm concerned that there may be something fraudulent going on. I did recently post a query in the Dell community forums about an Alienware keyboard, but as far as I know no support ticket was generated from that request. Is there any way to look up that support ticket and make sure that the survey was issued in error?

BuPXE-E61: Media test failure, check cable. Dell Optiplex 9010 USFF

$

I have a Dell Optiplex 9010 USFF. I installed Windows XP Pro x64 on it and I keep getting the following message when it reboots:

PXE-E61: Media test failure, check cable.
PXE-M0F: Exit Intel Boot Agent.
No Boot Device Found...

I tried the following so far:

- Tried a different hard drive: It gave me the same response on the second hard drive.
- Dell Diagnostics: Everything checked out,
- Replaced CMOS battery
- BIOS Boot sequence; Hard drive is on top and disabled "Diskette Drive" (just in case).
- Lan with PXE boot is already disabled.
- Had BIOS A13 and updated to BIOS A20, then A22.

This was a known problem since BIOS A04 but installing the latest BIOS doesn't fix it. Here's the link:

www.dell.com/.../EN

Now, the only thing that I haven't been able to try is to disable PXE in the BIOS because it keeps reverting itself back to enabled. It's just stuck on "Enable with PXE" and every time I change it to "Enable" (which would disable PXE) and reboot. It reverts back to "Enable with PXE".

Does anyone know what I can do to fix this?

Update: I reverted back to BIOS A15, still same PXE message. Then I tried A16, got the same PXE message. Only this time I was able to boot to the hard drive by pressing F12 and selecting it. I tried A18 thru A22 but I still have to go thru F12 to access the hard drive or else I would get the PXE message.

T7500 Riser Card broken ?

$

Hi,

I have a T7500 server (or is it considered still a workstation?) which stopped one day with  "uncorrectable memory error in Riser DIMM 3". I tried reseating the memory without success (same error) and after a few changes to the memory ( it has 12x 4GB modules from Hynix 2Rx8 PC3L-10600R) it turns out it runs just fine when I remove all Riser Memory and only keep 6 Motherboard modules. My understanding is that this is not such a great memory configuration and so this morning after an overnight job which ran just fine, I removed DIMM4, 5 and 6 from the MB and moved it to Riser DIMM 1 2 and 3 which I believe is an acceptable configuration. A crash happened after about 10 min.with "Uncorrectable memory error has been previously detected in RISER DIMM 3" - This means that since the memory chip came from the MB that previously worked well overnight, it is not the memory that is broken but the RISER Card perhaps ? Is this right ? If so, can I plug a new one right in after I transfer the memory and the CPU from the old one ? Can this work ?

BTW, when this error occurs, the system offers me to hit F5 for tests: the memory tests run for a while until they freeze without any additional error message. At this point I can do nothing but reboot the hard way.

Thanks,

Lothar

Optiplex GX755 - how do I access my network backup image?

$
0
0

OK, I think I've wasted enough time, now, so I'm turning to "more capable" expertise than mine (obviously)..

As the subject line implies, I've been backing up Windows 7 Pro (64-bit) to a network drive dedicated to backups (in fact, this 5 TB drive is named"PCBackups"...).  And since it made sense to have Win7 also create a 'backup image' as it performed the weekly backup, my thought was that if this scenario was to happen to me (first time with this Dell Opti, I might add...), I could save myself the 'grief' of having to install Windows "from scratch", the 400+ updates to both Windows and MS Office, all my software, all my documents, all the 'mapped drives', the network printers...etc.etc. ... ad infinitum...

So, two nights ago, the SSD I had installed in this 'rebuilt' OptiGX755, took a nose dive, so I picked up another at the local retailer (IMHO, it's amazing how inexpensive these have now become..Wow!) and I've been trying to figure out how to get this image back on the new SSD as 'easily' as possible.  But, after wasting WAY too much time trying to figure this out myself (with no success), I just have to ask for some help...  No matter what I've tried, I simply cannot 'boot' from the "System Repair Disk" that was created, and then successfully access the network-shared resource (which is this 5 TB disk) in order to make this happen..  So - uh - please... help a guy out...?

Just how the heck is this performed with this Opti GX755..?  It must be something as simple as needing the network drivers in the 'Advanced' radio button so it can 'see' and access the network .. or am I totally 'off the wall' here?.  I ask because, when I do an "IPCONFIG " command from the command line, it does not appear to receive a DHCP assigned IPv4 address,..  So that's why my 'hint' is that it's a 'network driver issue' ... and IF that's the case, then those who might be familiar with the Opti GX755 may already know it uses an Intel 82566DM-2 gigabit Ethernet interface.  I've downloaded what I consider every driver I can find, but "try as I might", I guess I am unable to 'install' the proper network drivers so I can access the server where this image is held...  BTW: I have had to do this on another PC, but the 'system restore disk' must've been able to supply the necessary network drivers, because it 'saw' the network almost immediately and I got to the backup disk with no problems.   But that's obviously "not happenin' " with this Opti GX755.

Anyone care to "lend a hand' in helping me to get this 're-imaged'...? By this time, I'm certainly not saving any time or frustration, but I would like to know how this is accomplished since we have two more of these Opti GX755's around the office, and I have no doubt that we'll be so lucky as to NEVER have to do this again...  And it'd be really great to have this done pretty shortly - like sometime this month? (sorry, my facetiousness is showing, again ... ).  Uh - "step-by-step" would be a GREAT help, here...  And thanks in advance to anyone who can give me 'the clue'...


Inspiron 3847 USB issues

I just purchased 4 Inspiron 3847's with Windows 7 64bit for my office and they are all having the sane USB issue.

When a scanner or printer connected via USB goes to sleep, the machine will not recognize the device and wake it up. The only way to get it to see the device is to turn the device off and then back on.

I've tried plugging them into different ports and tried updating the USB drivers from the Dell site and neither worked.

If I cannot get this resolved quickly, I am going to have to return them all. This is unusable in our office environment.

Any suggestions would be appreciated!

I have just set up my new All in One PC:  XPS 2720.  It has an NVidia GeForce GT  750M graphics card.  So why is Support Assist asking me to install the Intel HD Graphics driver?  Would installing this not disable my Nvida graphics card?

I got offered updates from MS today for Win 7+SP1, 32-bit, including one that's related to upgrading to Win 10 (KB3123862)  - No Thanks!

Another on the list is KB3156417, but when I click the More Information link on the update page, the MS site says "This page doesn’t exist."

Not going to install it unless somebody explains that one to me.  Google didn't help...

Thanks!

Dell Zino 400 Lid button missing

Hi there,

I recently got a Zino 400 HD off ebay and as advertised the button you press to pop the lid is missing.   I was hoping it was going to be easy to get a replacement button however I can't locate a supplier anywhere.


It appears to be a plastic insert that latches to keep the lid on, does someone know where i can get one for the UK?


For clarification the missing part is the button on at about 10 seconds into the video "How to dismantle and upgrade Dell Zino HD" that he presses to "Pop The Top"

(Please visit the site to view this video)

Your held would be welcome.

Thanks in advance.
