Question: Toshiba satellite l850, black screen after BIOS changes

After the changes in the BIOS (I don’t remember exactly what I changed), I pressed the restart and now at startup the black screen (The screen stopped showing signs of life) At the same time, Windows loads (I understood this, by sound). I tried to reset the BIOS by removing the battery, the result is zero. I took out the RAM, changed places, etc., it didn’t help either. I tried to connect to the TV set via HDMI, the image was not displayed. I saw in the video a method with closing the cooler hole (the laptop seems to warm up and start up), but also without result.

Answer: So it really works, but why the picture does not display, you need to figure it out, you can really only switch to an external monitor from under a loaded system, through the video driver settings. Since it was after changing the BIOS settings that such a problem appeared, then of course its glitch is possible, since removing the BIOS battery and de-energizing the laptop did not help for a while, then it makes sense to do it again, just wait a little longer, if it doesn’t help, then flash it with another, old save in advance. Moreover, I do not rule out problems with the matrix itself, the cable and the video output, but for starters it’s easier to flash, saving the old dump, if it doesn’t help, then you can already return the old dump and look for problems in the matrix, cable, video output.
It does not interfere with voicing the model of the motherboard and the full model of the laptop.

Question: Samsung NP355V5C (QMLE4 LA-8863P REV 2.0) Won't Start After BIOS Changes

It is required to reinstall Windows on a samsung laptop, for this, according to the instructions, it was necessary to go into bios and change fast bios mode to "disabled" and secure mode to "disabled" as well. After saving the settings and rebooting, the computer turns on, but the screen is black, it does not react to anything, the cooler turns to the maximum, the boot does not even reach the BIOS, just a black screen.
I tried to reset the BIOS by closing the contacts - zero reaction. I climbed the forum, the video chip died for people with the same laptop and a similar problem, but somehow strange, except for the settings, I didn’t change anything, and after a reboot, nothing works anymore.

Answer: Flashing the BIOS on the programmer will solve the problem!

Upd.
I managed to run Dell backup and recovery and try to find and solve errors through it. The program stood running for about an hour, there were no changes in the status bar. Then I turned off the laptop and turned it back on. Fully launched but in a temporary profile. Comrades, how to return to the human state?

Thread: Laptop won't turn on

Hello! I have an Acer Aspire V3-571G laptop. The problem is this. My laptop shut down while I was at work. The indicator that the battery is charging is on. When you try to turn it on again, the indicator goes out for a long time, the indicator next to it (light bulb) immediately lights up and also goes out. The laptop does not turn on. After a second, the battery indicator will light up again.
P.s. the laptop battery has not been working for a month, but everything worked without it. Give advice, maybe you need to solder the nest. I want to fix it myself. Thank you.

Answer: power cable as an option to try to change

Q: Backup BIOS settings

How can I copy BIOS settings to a file or device so that they can be restored later? Motherboard MSI b350 PC MATE, but also interested in whether at least some boards can do this at all.

Answer: Does this menu save/load only overclock settings or all settings?

Question: After repeatedly entering the BIOS, the computer stopped turning on

Good afternoon, dear experts. The problem is this: there is a monoblock Acer Aspire z3-605. I decided to install Windows 8.1 on it, but before booting from a USB flash drive, I had to try different settings in BIOS 20 times. everything is too complicated, well, or I'm not at that level yet.
So, after repeatedly entering the BIOS, changing the settings and then saving, the monoblock stopped starting altogether, namely: the fan starts, the power button is on, but the screen is black and the speaker does not emit a peak, as it did before. I tried everything: I juggled the RAM, reset the BIOS by removing the battery for a few minutes, turned off the hard drive, closed the contacts of the battery socket. I tried to insert a USB flash drive to flash the BIOS, but the light on it does not light up, which indicates that there is no voltage on the USB ports. I need your help, what could have happened, maybe the firmware has crashed or the BIOS chip burned out altogether?

From the last actions, except for installing Windows, updating the BIOS version (was version 5xk).
We have:
When you turn it off, the laptop then does not boot, it goes into a cyclic reboot, after the bios splash screen it turns off, then it starts.

You can go into bios. On the sysinfo tab sata port: not installed. In boot Sata HDD- null. Those. bios doesn't see it?

When you log in via an Acronis bootable USB-DVD - you can see the disk and partitions! Like this? When you turn off Acronis, Windows starts normally and continues to work normally. The disk is in disk management. The laptop normally goes to sleep and wakes up. It is loaded normally. On another computer in bios, though I didn’t look, this HDD works fine as a second disk. Rearranged the loops.

It is worth turning it off - it does not boot into reboot either.

Please diagnose and help fix the problem.

If you got to this article, then you had to face a problem when the laptop does not turn on and a black screen appears. This is the most common problem associated with the laptop hardware, and to be more precise with the hardware settings.

We thank the FIXIT.BY laptop repair service (Minsk, Belarus) for their help in preparing this material.

Below we will look at how to perform a hardware reset. This method helps when the hardware settings are off, but it will not help if your laptop has been flooded with water.

Reset BIOS settings

If the problem “the laptop does not turn on and a black screen appears” appeared after changing the BIOS settings, then you just need to reset and roll back to the factory settings. This action is performed in several steps.

You can learn more about the information “how to enter BIOS on Windows 10” or “How to enter BIOS on Windows 7” in our articles.

If these steps don't help, check out the next step.

Reinstalling the RAM module

The image may also not be displayed due to improper installation of the memory module or problems with contacts (very often this method helps to get rid of the problem “the laptop does not turn on and a black screen appears” after water or moisture gets on it, but before that, make sure that your laptop completely dry and in any case do not perform any action if it is not dry).

To do this, remove the RAM module, purge the connectors.

- If you have one stick of RAM installed, and 2 slots are available for it, just swap them.

Now let's figure out how to extract the RAM.

Hello everyone. Today's article will be, to some extent, a continuation of the story that we started in the previous one about HDD layout styles. It so happened that a computer with a rather interesting malfunction came in for repair. When you turn on the computer displays a picture of the BIOS, and further silence - just a black screen. Having gained experience and knowledge from the last article, I decided to experiment a little and solve the problem not by the usual reinstallation, but somehow in a tricky way. The ultimate goal is to get a working, starting computer with all the data. Read on to see how I did it.

How to fix black screen after BIOS splash screen?

Well, the first thing I decided to start with was to actually examine the computer for hardware malfunctions. I started by scanning the RAM. The RAM was a single 4 GB DDR-3 bar. I scanned with such an interesting program, which was already automatically built into the BIOS, as it turned out later (due to UEFI). Unfortunately or fortunately, but the scan did not show anything terrible, everything is in order. Next came the turn to scan the hard drive. This took a little more time. But even here the result was positive, there are no broken sectors. It turns out an interesting picture, the main tested parts are still working, but the problem with the computer has not yet been solved, so we turn on our heads and think about possible options. Then it occurred to me to try resetting the BIOS settings, but it happens, albeit not often, that he is the culprit, but as it turned out later, not this time. The reset was carried out as through the BIOS itself

and with the help of a special button on the motherboard.

The settings were all reset successfully, but did not lead to anything. And at this stage, I decided to spit on everything and just install Windows 7 from the disk. I insert the original image, at first everything loads quickly, but suddenly, at the moment when I need to select partitions, the installer throws me such a picture.

And this is where it dawned on me. It turns out that on this computer the HDD is placed using the GPT style instead of the MBR and perhaps all the problems come from this. Minutes of thought began .. the most mysterious thing for me was that Windows 7 was somehow installed on this very computer. Then, of course, I remembered that Windows 7 x64 can see GPT, which means that it is installed here. Now the further way to solve the problem for me loomed as follows:

Copy using LiveCD all the necessary data to an external drive, then delete all partitions and make an envelope according to the previous one;
Check BIOS settings, UEFI support, devices in Boot Order;

And as you might guess, I went the second way. I went into the BIOS, checked all the settings, it really supports UEFI, then I went to the boot device section and this same boot-order was interestingly divided into two parts, on top of the device (but under the UEFI block), just below almost the same devices ( but under the Legacy block).

In the search, I found the necessary information, and then an insight awaited me again 🙂 In the last article, I even touched on this a little. In general, in short, how these two blocks differ (UEFI vs Legacy). You can boot from your external device in the same way, either from the UEFI block or from the Legacy block, only in the first case your BIOS will apply special algorithms that will allow you to see! HDD partitions in GPT style. In the case of Legacy, you will see partitions only if your hard drive is partitioned using the old MBR technology. And that's exactly the whole gag. Because my attempts to enter the "System Restore" section (installation disk) for some reason always failed. Now, being a good judge of this, I again cling to the Windows 7 x64 installation image, boot from it. Continue to "System Restore"

Black screen when turning on laptop.

This is the most common problem associated with the laptop hardware, and to be more precise with the hardware settings. Below we will look at how to perform a hardware reset. This method helps when the hardware settings are off, but it will not help if your laptop has been flooded with water. In the article " Laptop does not turn on, causes and solutions"We looked at the physical problems associated with the appearance of a black screen.

You perform all actions at your own peril and risk, if you are not sure about something, it is better to contact the service center. Typically, the cost of repairing a laptop is significantly different from the cost of repairing computers.
How to perform a hardware reset
To perform a hard reset, follow these steps:

1. Disconnect the laptop from the network or other power source. This includes disconnecting the laptop from the charger, as well as removing the battery.
2. You need to press and hold the power button for about 20 seconds
P.S. Why is this necessary? Everything is very simple. The laptop stores the residual charge of the capacitors to save the settings. When you turn on the laptop without a power source, this charge disappears and all settings are lost.
3. After that, insert the battery and connect the laptop to power.
4. Turn on the laptop and select, using the arrows on the keyboard, the normal boot of Windows.

If these steps do not give any result, go to the next step.
Checking the health of the laptop screen

Checking the health of the laptop screen can help solve the problem with "Laptop does not turn on and a black screen appears." This method is recommended to be used if, when you press the power button, the laptop shows signs of life, i.e. power indicators, railway operation, etc. I start to blink, the cooler starts to make noise. In this case, it is recommended to connect an external monitor and restart the laptop. If the laptop turns on and the OS boots up, then there are problems with the screen and you cannot do without a service center.
Reset BIOS settings
If the problem “the laptop does not turn on and a black screen appears” appeared after changing the BIOS settings, then you just need to reset and roll back to the factory settings. This action is performed in several steps.

1. When you turn on the laptop, wait for the f10 key for 10 seconds to get into the BIOS.
2. Then you need to press f9 and enter to return to the factory settings.
3. Press the f10 key and enter - this action saves the settings and restarts the laptop.

If these steps don't help, check out the next step.
Reinstalling the RAM module
The image may also not be displayed due to improper installation of the memory module or problems with contacts (very often this method helps to get rid of the problem “the laptop does not turn on and a black screen appears” after water or moisture gets on it, but before that, make sure that your laptop completely dry and in any case do not perform any action if it is not dry). To do this, you need to remove the RAM module, blow through the connectors (if you have one RAM stick installed, and 2 slots are available for it, just swap them). Now let's figure out how to extract the RAM.

1. When disassembling a laptop, the very first step is to disconnect it from the power supply, and also remove the battery, and then only proceed with the disassembly itself.

A little advice before you start to disassemble the laptop. The bolts have different heights, so group them and put them in different boxes.

2. Many laptops have a dedicated RAM compartment that needs to be unscrewed. If you are unlucky and your laptop does not have such a compartment, you need to completely unscrew the back cover of the laptop.

The figure shows what the RAM compartment looks like and how it needs to be unscrewed.

The RAM is held with the help of 2 latches on the right and left sides, therefore, from the beginning it is necessary to bend these latches, and only after that remove the RAM. In the figure, the number 1 shows where it is necessary to bend the clamps.
4. Reassemble the laptop, insert the battery and connect to the mains. Turn on your laptop.

If these steps do not give any result, you need to reinstall the BIOS. To do this, you need to go to the manufacturer's website, find and download the latest BIOS version. The archive will contain a readme file with detailed installation instructions. Reinstalling the BIOS must be performed in the very last case, but in general it is better to contact the service center, because the problem may not be in the BIOS at all, but, for example, in the north or south bridges, video card, etc.
