[Kernel-packages] [Bug 1637031] Re: In cold startup there is dark/blank screen
The real problem is grub. When I ran boot-repair, this tool gave the following answer: "The boot files of [The operating system being used - Ubuntu 14.04.5 LTS] are far from the beginning of the disk. Your BIOS might not detect them. You may want to retry it after creating a / boot partition (EXT4,> 200MB, beginning of the disk). This can be done with tools like gParted. Then select this partition via the [Partition / separate boot:] option in [Boot Repair]. (Https://help.ubuntu.com/community/BootPartition)". This problem is problematic to find because when I turn off the computer and then startup again several minutes later, the computer works very well, but if I startup the computer several hours later, the computer fails miserably. I think of that this problem is a bug because the manual in /usr/share/info/grub.info.gz says: "GRUB understands filesystems and kernel executable formats, so you can load an arbitrary operating system the way you like, without recording the physical position of your kernel on the disk.". If this is true, what: The boot files of [The operating system being used - Ubuntu 14.04.5 LTS] are far from the beginning of the disk, means? I do not know. ** Changed in: linux (Ubuntu) Status: Incomplete => Invalid -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1637031 Title: In cold startup there is dark/blank screen Status in linux package in Ubuntu: Invalid Bug description: When I startup my computer, I can see very fast screen given any information.

[Kernel-packages] [Bug 1637031] Re: In cold startup there is dark/blank screen
Answer to:Joseph Salisbury (jsalisbury) Firstly I want to say thanks a lot! Before I test the latest upstream kernel, I want to give more information about this problem 1) I was reading a web page: PC Repair and Maintenance: In-depth Look at Power Supply, that it was reading By Scott Mueller Feb 28, 2003 (http://www.informit.com/articles/article.aspx?p=31105) 2) In the page 2, I found the following paragraph that describes the problem: If you find that a system consistently fails to boot up properly the first time you turn on the switch, but that it subsequently boots up if you press the reset or Ctrl+Alt+Delete warm boot command, you likely have a problem with the Power_Good timing. You should install a new, higher-quality power supply and see whether that solves the problem. 3) The unique difference is that I need to push reset button case not Ctrl+Alt+delete because keyboard is death 4) I changed the power supply for another with 650 W output 5) But the problem continues: startup+reset to keep the computer running 6) I was reading carefully the following paragraphs: "The Power_Good Signal In addition to supplying electrical power to run the system, the power supply also ensures that the system does not run unless the power supplied is sufficient to operate the system properly. In other words, the power supply actually prevents the computer from starting up or operating until all the power supply voltages are within the proper ranges. The power supply completes internal checks and tests before allowing the system to start. If the tests are successful, the power supply sends a special signal to the motherboard, called Power_Good. This signal must be continuously present for the system to run. Therefore, when the AC voltage dips and the power supply cannot maintain outputs within regulation tolerance, the Power_Good signal is withdrawn (goes low) and forces the system to reset. The system will not restart until the Power_Good signal returns. The Power_Good signal (sometimes called Power_OK or PWR_OK) is a +5v (nominal) active high signal (with variation from +2.4v through +6.0v generally being considered acceptable) that is supplied to the motherboard when the power supply has passed its internal self tests and the output voltages have stabilized. This normally takes place anywhere from 100ms to 500ms (0.1–0.5 seconds) after you turn on the power supply switch. The power supply then sends the Power_Good signal to the motherboard, where the processor timer chip that controls the reset line to the processor receives it. In the absence of Power_Good, the timer chip holds the reset line on the processor, which prevents the system from running under bad or unstable power conditions. When the timer chip receives the Power_Good signal, it releases the reset, and the processor begins executing whatever code is at address : (usually the ROM BIOS). If the power supply cannot maintain proper outputs (such as when a brownout occurs), the Power_Good signal is withdrawn, and the processor is automatically reset. When the power output returns to its proper levels, the power supply regenerates the Power_Good signal and the system again begins operation (as if you had just powered on). By withdrawing Power_Good before the output voltages fall out of regulation, the system never sees the bad power because it is stopped quickly (reset) rather than being allowed to operate using unstable or improper power levels, which can cause memory parity errors and other problems." 7) My motherboard is a GIGABYTE P35-DS3L and pin 8 of the main power connector receives Power Good signal 8) When power supply is ON, the following occurs: the main task performed by SMPS, is to inform about the good power supply. As I told if the voltage is more/ or is less, in both the conditions a computer cannot work. As soon as you supply power to the computer, the SMPS checks the voltage level's its providing to the motherboard. If the power signal level is perfect, then SMPS will send a POWER GOOD signal to the motherboard timer.On receiving this POWER GOOD signal from SMPS, the motherboard timer will stop sending reset signal to the CPU. Which means the power level is good and the computer can boot. 9) Bootstrapping: Something has to be programmed by default, so that the CPU knows where to search for instructions. This is an address location in the ROM. This address location is almost always constant in X86 based computers. The address location is :h. This address location is the last region of the ROM. It only contains one instruction. The instruction is to jump to another memory address location. This JUMP command, will tell the location of the BIOS program in the ROM. This is how the computer will come to know where the BIOS program is located. 9) The Role of BIOS in booting process: The word booting comes from another word called bootstrapping. The computer knows how to bring itself up, when
