Power supply: The computer does not turn on after an electrical failure

Subject: On the right side, the light was turned on, when the light was turned on, I decided to turn on the computer by pressing the button and the cooler started spinning, the lights turned on, the light turned on, the light turned on, everything was working, and there was nothing on the monitor, just a dark screen and I was seeing the problem. shiv let's come with rank. The computer is vibrated, the cover of the system unit is opened and the chassis jumper on the motherboard is felt, it is pulled out from position 1-2 and inserted into position 1-3, the computer is turned on through the quill, and it is repositioned back to position 1-2. Bulo, turn on the computer and EVERYTHING was requested!!!

Power: After turning on the electricity, RAW system on disk

Having first read this topic, I have already tried different options. chkdsk /f tried. It didn't help. testdisk scanned, but did not correct anything.

What’s so great, there are two identical screws in the computer, in the sour future there was a wealth of information, films, games, etc. saved. And the other practically did not vikorist, well, there is no need for so much space. 33 giga with 2 TB maximum amount of vikorist. When you follow SMART, this one has the same body as the first one. And when the trash was scanned, the sectors were the same.

Ale vin is still working and there is no important information at all, but first of all I would like to remove the photos, everything else can be re-entered. Can you tell me what you can try? Yuck!

Power supply: The printer loses its adjustment due to regular electrical failures. What can you earn?

The robot is equipped with an HP LaserJet 400 M401dn printer, which, through electrical connections, requires manual adjustment of the boundaries (IP, mask, gateway) and, as a result, it is not possible to work on it. We hope for the stability of the work and the exchange of information among all computers while fixing the IP, like the printer. How can I overcome the description of the failure in the printer settings, so that after the electrical failure, it will be possible to repair it in the future?
There are two important points in the troubleshooting instructions:

2. If the device is installed behind another standard HP TCP/IP port, please be sure to contact your printer before changing the IP address.
3. If the device is installed behind another standard Microsoft TCP/IP port, use the hostname rather than the IP address.

It seems that they have a strong desire for confirmation, but that’s not enough.
2. What is the standard TCP/IP port for HP?
3. How can I verify that a device (such as a printer) is installed on a different standard port for Microsoft TCP/IP? Is it checked on a computer or printer?

Subject: The message on the other hand is absolutely obvious: marvel at the power of the port; from the first meal - as you haven’t found 10 cows in 3 years to Google the answer - check back until you have time for active participants to copy the answer from the side of Google to the side of those.

Power: Vibir UPS, which turns on when the electrics are turned on

PS. Needs are the cheapest

Subject: These uninterruptible machines, which I previously bought from a great deal - “IPPON Back Office 400”, definitely do not go online on their own. If I found out about this, starting with the brothers of uninterruptible Cyberpower. The stench turned online when the electrics were turned on, but it had never been lost on one important server. So I started shukati and placed food here. Even if I then ran a test of the uninterruptible server on that server (Cyberpower standing there) - I couldn’t solve the problem - DBZ I feel like turning online. Anyway, I don’t care about all this, I was glad to hear about it here and bought an APC, the axle is “APC Back-UPS BX650LI”, which is the cheapest price for APC, which I know. And they gave the purchased brand simply “about every incident,” so that one episode of inaccuracy is the basis of great incompetence. Ale APC is obviously more expensive.

Power: acer v5-551g (DAOZRPIB6B0 REV: B) does not turn on after ram is turned on

Subject: So I don’t understand, and that there is a stink for the RAM reconnection, only from the removal of the pins (you can see in the photo), I understand that the resistors there are culpable are 10 kOhm, but how to determine where the contacts are from the pins don't go To my understanding, I can’t confirm that. Is there still more r614-r613 than duplicated r626-r625?

Power supply: PC Powered on only after connecting to 220

I have this problem. Gravity at the gru, the computer froze, the blue screen of death popped up,
Then the obsession set in and the computer became re-enchanted.
When I called again, the same thing happened again.
And from this moment, when the PC is re-engineered, the fans are all humming,
and the monitor is black. I turn on the life 220. I press the ON button on the computer all the time.
I turn on the 220 computer, it will switch to Windows and work normally.

Windows appears again and then freezes (black screen, instead of logging into Windows)
It only helps to have an external 220V connection.

max1488, there are “jokes” with the electric lance, that with a single power supply and electric lance, the computer can turn on without changing the wiring, but you can try the axis with another later reference power supply.

At first the joke started in the fact that a blue screen appeared... then the computer stopped turning on after rebooting. Then, after hibernation mode, it went out completely. (The MB has cooled down the percentage?) If the problem is in the “power supply”, then why did you restart the computer after removing the battery?

I'm sinning on the hard disk chi vids.

Now the computer has been restarted 6 times normally without any jokes)
Ale Varto put Yogo into sleep mode. It is already possible to bring it out there without removing the battery.

The computer does not turn on after the light is turned off, please help!

1. For starters, try sniffing the smell of burnt food from the life block (BP).
   If there is no smell or you don’t feel it, do this:
   1) Pull out the power cable from the computer (the same one that goes with the power supply) and insert it back, and the same there, where this wire connects to the outlet.
   2) If that doesn’t help, open the system unit and remove the small round battery on the motherboard, and then try to start the computer without it through the coil.
   3) If that doesn’t help, try downloading all the files from your computer that you can’t do without. For example, remove one RAM memory, and remove another strip, including a memory card, a sound card, a hard drive and a video card. Try starting your computer without them.
   4) If nothing helps, put everything back in again and check all the sockets in the middle of the system unit and all the arrows that go into the system unit and socket.
   5) If it doesn’t help, borrow some kind of life block from a friend and try to start your computer with it.
2. BP is dead. If the computer, which previously worked normally, suddenly stops blinking (so that after pressing the button nothing comes up at all, it’s stupidly quiet), then the reason may be 100% due to a dead life block
3. life block melodiously zgorіv

Just because the computer doesn’t boot up doesn’t mean that someone’s joints are broken, otherwise they need a call from the driver, and the case needs to be repaired. The computer does not turn on for other reasons. Let's, as per tradition, look at this point using a number of examples from practice.

Let me just say: everything that will be described below needs to be considered as the simplest version of the situation if the computer does not turn on. It is quite clear that the reason for this may be blamed on something else: or we think it is something else. If you have, then for this reason we have the same article on our website.

Here I want to talk about those that, behind all these wicked “thorny” problems, people who spend time not making the most elementary and obvious speeches and who do not use the computer can create a lot of unnecessary work.

For starters, let's take a look at the widest episode, if the computer doesn't get stuck, which throws the average student into a catatonic stupor and urges him to press the "power" button to no avail, and then call the master :) This is what we see on our work regularly when the rapt is connected and electricity.

The master arrives, puts one hand behind the system unit, to work there and start the car. The seller of joy and joy distributes inexpensive tsukerki and stove :)

With song periodicity after that, as The light goes out and the computer won't turn on. Let's understand why this is happening. At the moment of a sharp drop in voltage, the life block shuts down. The voltage drops quickly, but behind the shell of the capacitor capacitors near the block itself - there is not enough voltage to prevent the device from reacting.

Note: In a clear block of life there are different stages and types of healing. The axis is the widest of them.

• OCP (Over Current Protection): anti-stress;
• OVP (Over Voltage Protection): against voltage surges;
• OPP (Over Power Protection): sometimes called OLP;
• OTP (Over Temperature Protection): overheating;
• UVP (Under Voltage Protection): for low voltage;
• SCP (Short Circuit Protection): short circuit protection;

In this case, the computer does not turn on due to protection against voltage cuts. Vaughn controls the supply of the jet by life lines. This requires additional charging of a special capacitor in the protection circuits, which, when the charge is accumulated, prevents the system from drying up. For the system to turn on, all we need to do is pull out the power supply cable (220 V) from the life block for 3-5 seconds and install it back (with a discharge capacitor).

In this manner, we “throw away” the protection of the BP and the wine can proceed further.

This, as they say, is a “classic of the genre” :) Now I would like to talk to you about more atypical episodes when the computer does not turn on. In my practice, they have occurred a number of times, and I wonder what is sufficient to know about such a possibility.

Well, of course there is a “guessing session” :) One of the working office machines had a USB mouse installed with the following adapter for the PS/2 port:

Perhaps, this same adapter, within an hour, started to trigger a local short circuit (short circuit) in the socket, which automatically led to the activation of the power supply circuit to the life block. As a result, the computer didn’t get used to it, not getting used to it at all, but after connecting the mouse itself through the adapter, it didn’t understand, but after connecting the device directly into the USB port, everything miraculously requested.

So - please respect.

Another example: call the management - The computer does not start". I arrive - it’s working, it won’t start. I try a couple, which I sort out, call the place. No result. I pick up the system unit before us in IT for “poly analysis” :). I bring it home, connect the cables and input devices - everything works!

Using the trial method, it was revealed that the reason that the computer would not start was the keyboard, which did not work (more precisely, the microprocessor). The keyboard has been replaced. It may happen that when the keyboard is not working, the internal system speaker will hear three short beeps.

And here’s another outburst from my practice. Please refrain from bringing your home PC, even: The computer won't connect, I don’t know the reason, marvel, be kind. Why not help a good person, let’s do it!

I bring it to my office, take it out of the box, put it on the table and conduct a thorough visual inspection. What should I tell you? Rather, I’ll just show you a bunch of photographs:

Why did the people bother with the car!? And this is a mysterious phrase: " won't turn on, I don't know why?..." :)

What do I want to increase your respect for? During the diagnostic period, try to look at all possible options. Think broader, don’t get too hung up on the “standard” range of problems. Since the computer does not connect, you know, all its external peripherals and input devices, is the reason for this? Well, since the computer is not yours, do you vouch for the level of technical adequacy and literacy of your authorities? :)

I sincerely wish you good luck in this painstaking task!
