HP Laptop Pavilion DV7 is black after rebooting the operating system, the fan is running at full speed and no input works anymore, why?
Because I'm sure other data is being downloaded or updates are being made. Just leave a two days connected to electricity and internet
Thank you. Yes, I thought so synonymous already the laptop reinstalled everything. But he leaves the Bipdschirm black because I was undecided. And, especially that can take so long?
If the notebook does not even show a startup screen, I see three possibilities:
The operating system hangs in idle state. With your notebook, you can simply take out the battery and force a clean reboot. When the boot screen shows up, the error is somewhere during the reinstallation. Eventually, it helps to start cmd.exe under "Run" and to completely deactivate the idle state with powercfg / h off.
The fact that the operating system hangs can also be due to defective hardware, which causes errors.
Helps the battery does not take out and you do not even come to the start screen, it is certainly a hardware defect that happened only by chance with the reinstallation.
If you restart it comes but still a start screen leads to the BIOS?
Firstly, they are too hot. Secondly, too loud because the fan is always on. Thirdly, after a few years there are no updates anymore. And you can throw it away. Fourth, this is annoying at Win7 at least it was like that to make the updates and security CDs constantly. Like an idiot. Can someone please HP times the opinion? And of course Gates? With his Microsoft.Unfassbar what they do with their work in the world for a Elektromuell.Und then in third and fourth countries shipping where then children in order not to starve the toxic components herausholen.Am beach. Where everything flows back into the sea.Tolles business model. Can you be proud of it. Long live the American Way.
No. That's my problem after re-installation. Oh how I hate that thing.
So if you turn it on, no screen is displayed?!
Also not the boot process?
Have you ever connected an external monitor?
Have you ever tried hard drive and CD / DVD ROM disconnect (expand) and then start the notebook?
Even older notbooks can be used for a long time stress-free by installing a Linux on it (I use for Linux Mint Xfce, which needs little resources).
The HPs can't all be lumped together. There are good and moderate and lousy notebooks as with almost all manufacturers. However, the bloatware at HP is terrible.
With the combination too hot + loud fans one can do also with fan control software little (except the fans / air channels are simply dirty ^^).
Did not take out the battery helped?
Somehow you have to come back to the start screen. Should I unscrew everything that is not needed? What if I take the record and then start? Will anything be displayed then? Like no more disk in the case or something? As with the Sim? Haha.
But I'll do that soon if the filth does not work.
I have not yet ne.Waere the HP sign on d.Rueckseite then not synonymous? If the display had something?
No. The logo will be lit anyway.
If the notebook after taking out the battery continues to show nothing (black screen) and the fans turn up permanently, I think a defective motherboard for the most likely:
If the disk were defective, the BIOS would start and report "no proper boot device". If you remove the disk and bootest, there's the same message and you can be sure that it is not due to the software.
If the display or the display control were defective, the fans would not turn up permanently because the notebook boots normally even without a display. This could also be tested with an external monitor.
The motherboard is available for a few euro as a spare part (but used and unaudited). Since you have to decide for yourself, if you take the risk of a repair attempt.
