Start up Probelms HP Pavilion Slimline

Hi, I have a HP Pavilion Slimline s7510n and it won't start up. It's almost like in a sleep mode and I can't get out of it. The PC powers up, as do the fans, mouse, and anything plugged into a usb. However, nothing on the monitor and keyboard. The power light stays blue and doesn't go into the usually "sleep mode" yellow also.

I'm the same guest from before and I've got my slimline back up and running. I found the solution somewhere else, can't remember where as I was on someone else's computer, but suggested a boot up problem with some USB devices. One suggestion was to power the computer down, unplug all USB devices and power it up again. The only USB device I had was an HP all-in-one printer/scanner. I unplugged that and the computer booted right up. Hope this helps!!

Unplug the AC power, remove the battery, wait a full minute and then reinstall AC and battery. See, if you now power up. Most power up problems are related to AC power, DC input jack, motherboard, memory or processor. A lot depends on your comfort level and expertise in how far you should go in self diagnosis and repair. Good Luck.

no Monitor stated. (maker, CRT, LCD what?)
The monitor is not fibbing to you BTW, the PC did go dead or to sleep. seems its monitor monitor of some kind with DVI.

if the monitor works on other PCs then the monitor is not bad.
i Bet it works (old ones 2002, have a hidden deep internal sleep mode. and is not yours IM sure now) DVI IS THE ONLY CLUE THERE.
So PC is dead. this PC came with only VISTA new,
is it still VISTA?????????
HP has support on it still
here (carbon dated by me 2008, IIRC)

this year,? get all those files and books there backed up
when HP support ends after 10 year rule, (be savvy?)

what keyboard USB or wireless keyboard mouse
use wired USB keyboards if wireless the battery is dead. easy no?

now in VISTA, go to Control panel, click power
turn off all sleep modes and all hibernate modes
the turn off screen savers, if turned on , disktop . RC right click
in display settings or personalize, turn off , need login to come out of sleep or screen saver.
try a real keyboard, that has USB cable yet? be first thing to do.
always keep a real keyboard, handy,,,
batteries fail. in all wireless devices like this (inside them)

luck you desktops have lies DIM fails. there are many.

one other way , and common is PC overheated.
all do that.

#1 all time cause of overheat and PC shuts down.

My computer hp s3700f keeps going black or sleep. Mode


You can prevent the computer from going into sleep or hibernation mode by going to the CONTROL PANEL - POWER SETTINGS.

Once here, change the settings to High Performance.

You can also go into advanced properties and manually change all of the settings - including when the hard drives go to sleep (I set this to NEVER), when the monitor will go to sleep (again, I set to never).

Can HP dv2715nr hibernate instead of putting it on sleep mode?


It sounds like the hibernate feature is missing from the power options list. Click on start button, select shut down, and then hold shif or ctrl and stand by should change to hibernate.

Let me know how you get on.

I have a HP Pavilion Entertainment PC. It worked

It could be a problem with the update. You could have used system restore to go back to before you installed the update. Re-imaging probably cancelled that. I would check for virus' before going any further. Download a program called malwarebytes (free version), install-update and scan. If nothing comes up try the system restore or uninstall the service pack. You can always reinstall it again later.
