All-in-One M93Z - Powered through MSW Inverter?

Q: All-in-One M93Z - Powered through MSW Inverter?

Would any significant problems be expected if I was to try to run my M93Z off of a modified sine wave inverter? I know that pure sine wave inverters are recommended, but it also sounds like a lot of desktop computers have components that monitor and smooth out the power input anyhow. I don't intend to use anything too heavy like video games, just a lot of Excel. Any thought woukd be greatly appreciated - thanks in advance!

I have a Toshiba Laptop... A week ago, my screen has started going black and coming back. Just two days ago, my screen went black and did not come back. I thought my screen was dead but then I figured that the back light of my screen was gone because when I look at the screen carefully, I barely see the things on my desktop....When I turn on my laptop, I can see my screen for 3-4 seconds, then it goes black again. Same thing happens when I log on after log off... It again gives me the light about 3-4 seconds after just logging on, then it goes black again. I finally opened up the screen, and found the display inverter... and it again gives me the light 3-4 seconds after I plugged out and plugged in the inverter cable. I am not sure whether the problem is the inverter itself of the inverter cable. I really need help.
 

A:Distinguishing between display inverter and inverter cable problem.

It sounds like the inverter may be sensing an overload on its output(s) and shutting down after a few seconds. Some possible conditions causing it could be 1) the backlight lamp(s) failing, 2) arching of the inverter output cable to itself or the frame of the LCD panel, or 3) a failure of the inverter's overload sensing circuit that makes it think it is being overloaded, when it really isn't.

WARNING: Use extreme caution when working around a CCFL inverter with power applied to it. Portions of it will have hundreds of volts of electrical energy on it. You could receive a nasty (and possibly fatal) shock if you come in contact with the high voltage.

Hi there

Intuitively one might think using Powered (from the mains) external USB HDD's would require more power from the computer as well compared with those small self powered units.

I've no way to measure this but I'm sure the small units might consume MORE power as the computer has to supply all the power for Disk rotation and the USB I/O controller.

I only ask this because I need to put two large powered USB units (both with 2 X 3 TB Raid 0 HDD's in each unit) on to a USB 3 Hub.
The two HDD units seem to perform perfectly well whether connected to the chargeable port on an HP laptop or the "non chargeable" ones.

The RAID 0 is powered by the HDD itself (internal Hardware RAID) --used RAID 0 for speed -- don't need to mirror etc - I've enough backup if the whole thing goes bonkers. !!

The files on these HDD's are serving music and video so not intensive used -- don't seem to have any problem streaming media from the laptop.

Any engineers out there - curious over what is the actual load (power wise) on the computer if a POWERED USB HDD is used compared to a Self powered one. Note the Hub I'm using is not also powered.

I'm trying to find out if I can get a digital surround sound output from my M93z. As far as I can tell there is only one digital audio output native on this PC - the DisplayPort audio connection.  This shows up as Intel HD Audio in the driver list.  I am running Windows 10 x64 and have updated all of the drivers and utilites from Lenovo using their tools. I have had my DisplayPort connected to my TV through the Lenovo supplied DisplayPort to HDMI dongle.  I recently purchased an HDMI audio extractor, one with a switch where you can have it request the PC to provide it with 5.1 audio output.  Even with the TV disconnected from the audio extractor the PC sees the audio extractor device, so this should eliminate the TV from the setup. I know that the PC will only output the audio format that it has to play from a particular program.  However, when I go to Playback Devices and check the properties of that audio connection it states that the maximum supported channels is 2.  I would expect that if everything is being detected correctly that it would state 6 or 5.1 or something like that. (Yes, I realize there are other options to try and get this to work.  Before anyone suggests to purchase a USB sound card please try to answer my question below or help solve my problem.  Changing to a USB sound card is not what I'm asking about here.) So my question becomes: Does the Intel HD Audio device that is built into the M93z...

We got in office new AIO ThinCenre M93Z. When turning on the PC, there is no noise at all; however after working 2 hours, the noise of fan drives everybody in room crazy. It not so loud, however it sounds like wind around the blocks in autumn and the noise is not at same frequence but always going up and down, depending on speed of fan.We already checked internet for ours, nothing helped. The CPU temperature is about 40 degree celcius. The tool fanspeed cannot detect the fan, in bios we already put to "acoustic" (sounds like a joke for this setting).We would be so happy if anybody could help! For Thinkpads, there are special tools for fan control; however there seems to be nothing for Thinkcenter AIO PCs. If it would be a private PC - no problem to open the case, put better fan inside; however it is new brand new PC from company and we cannot do hardware modifications.

Hi all, We are having issues applying Thinkcentre M93z BIOS update.  The update itself completes successfully but the following reboot produces the error: "Error 0162 - Setup data integrity check failure"?Press F1 to enter Setup, F2 to resume? At this point it doesn?t matter how many times you press F2 you always receive the same error during POST.  The workaround has been to enter the BIOS and press F9 then F10 to save and exit.  Once this has been done the machine boots without displaying the 0162 error.  If we were manually walking around updating the BIOS on each machine it would be less of an issue but since we are carrying out the BIOS updates via SCCM, visiting each machine is not an option.  It doesn?t matter if you apply the BIOS manually or via SCCM, you see the same error.  For reference we are updating to the latest BIOS revision: FEKT50AUS. Any ideas? Many thanks

Here's the problem -
4 year old Gateway laptop, LCD went dark suddenly (could just make out screen in certain light.)
I figured out it was the inverter, order a new one, and installed it.
Hooray, everything worked fine. Bright clear screen.
I'll say here that the drive was wiped, so when it boots it boots to "No OS found."
Booted it up and left it alone for it to charge battery. Sat for 1/2 hour with no problem with "No OS found" bright and clear.
Re-booted to begin install of OS and it lit up, showed 'No OS found" for 60 seconds, and then goes completely black, not even faint.

So I can't tell now if this inverter went, backlight is shot, or ????
Since it starts every time bright and clear I have no idea. It just goes black 60 seconds after I turn it on.

Recently my Inspiron 8600 started booting with a black screen. Shining a flash light on it, I could see login prompt then XP desk top. This kind of thing usually points to the Inverter; however, both the CCT (Cold Cathode Tube) and wiring could also be the source of my problem. I have dismanteled the display down to removing the bezel and freeing up the LCD panel. Where do i go from here to be sure which component is the cause f my problem?

Thanks in advance
 

A:LCD inverter?

To be honest, the best way is by substitution of the inverter or the backlight. Whichever fixes it is the problem.

The high voltage produced by the inverter could be measured with an appropriate meter, but as it is effectively a ballast the results could be affected by the CCT backlight, it may be hard to deduce just which is the problem. Open circuit voltage would also be inconclusive, it could still be a defective inverter that falls over with the load and fails to strike the CCT.

if inverter is bad, you can still see the image on the screen. if you don't see, so there's lack of LVDS signal from MB to LCD screen. in this case, you should check connection between MB and LCD, and if your laptop has nvidia geforce7200/7300/7400 videochips or nforce 6150go video, you should repair this laptop via warranty service.

I have a DCL LCD19A 19" LCD Monitor. It went dark and when I unplug then plug it in it lights up for a few seconds then goes dark again. I paid $139.00 for the monitor, and when I queried the manufacturer, they said they won't sell me the part, but for $99.00 plus shipping they will repair the monitor. Since this would probably end up costing me more than the original cost of the monitor, I am surely not going to ship it to them. I have opened the monitor (I am fairly technical and a Ham operator), and I cannot find a separate inverter. It appears that the monitor has a single board.

Are they integral with the system board or separate components?I ordered an X61 tablet on 9 Nov and received it on the 27th. The backlight kept crapping out so it went back to Easyserv on 4 Dec. I got it back on the 20th and the info sheet said they'd replaced the system board and restored the HD to as-shipped state.Yesterday the backlight started going off again, and today it wouldn't come on at all. Obviously it's got to go back again, but I'm curious if replacing the system board was the right thing to do.

If you have a problem with a laptop screen is there a definitive way of telling whether it is the inverter that has failed or the screen? I have seen a number of forums mention the possibility of either but no way of actually definitively telling.

I have a HP NX9105 where the display is extremely dim but is just visible in light and an inverter will cost a third of the price of a screen but I don't want to buy both if only one needs to be replaced. Have tried the Fn buttons and the screen button.

Any help greatfully appreciated.

Regards, stucuk

I was given a slightly beat HP laptop when one of my customers upgraded. The video chipset still works (i.e. works fine when attaching an external display) but the screen itself is acting up. When the computer is powered up, the backlight turns on but there is just a single vertical line of colored pixels. I know all of the pixels work because if I tap the side of the screen they will display normally at any given time, but then the picture seems to get distorted or slowly burns out. So I'm thinking the inverter is junk, which is an easy enough fix... but I wanted to ask someone who has a bit more experience with this sort of thing. Any ideas?
 

A:HP dv5000 bad inverter?

The LCD panel itself might be bad, but you can check all cable connections before you purchase any parts. i really don't think it is the inverter

I've had my laptop for around 3 years now and just last week, the lower half of the screen flickered for a few seconds. I never thought much of it but over the last few days, the problem has become more noticeable. I have done some searching around and this isn't an uncommon problem, across all makers of laptops.

I have been advised to hook up an external monitor to see if it flickers in sync with the laptop, if it doesn't then it is most likely a failing LCD Inverter.

Does anyone know how much one of these would cost over here in the UK, or if they are all compatible?

Best regards

Gavin

A:Satellite Pro P - New LCD Inverter

Hey,

The exact price is depending on your notebook model and display. Different notebooks have different hardware so there is no common inverter for all displays.

An exact answer you can get from an authorized service provider in your country. The guys have access to all Toshiba databases so they can tell you the part number and how much it would cost.

If you have more questions, just post again! :)
