Laptop won't recover from Sleep mode

HP Pavilion dv4
Microsoft Windows 7 (64-bit)

In the past, after putting the laptop into Sleep mode, some time later (hours) it would frequently "wake up" and stay on.

 

After the laptop suffered a crash of its hard disk, which had to be replaced and Windows 7 reloaded, the problem has gotten worse. Now it almost always wakes from Sleep mode of its own accord, but when it does so the screen is blank and the computer is unresponsive. If I power it down and restart it, it doesn't start but instead the Caps Lock and Scroll LEDs blink on and off with nothing more happening. The only way I've found to restart it is to unplug the power supply and physically remove the battery for a few seconds before trying again.

 

Any ideas as to what is wrong?

Laptop won't recover from Sleep mode

Hi @coffent,

 

Welcome to the HP forums! It is a great way to engage, post questions and find resolutions by working with specialists in the HP community. I understand that your notebook has not recovered from sleep mode and there is an issue after the hard drive was replaced. It will be a delight to assist you here.

 

A commendable job was done by trying  some basic troubleshooting by unplugging the charger and removing the battery and waiting  for a few seconds, before firing it up again. You have done awesome troubleshooting before posting your question in the HP forums. It is always a great pleasure to work with tech-savvy and technically sound customers like you. Kudos to you for that. I am amazed at your technical skills and levels of technical knowledge.

  • For better clarity, I would require more information regarding the unit to assist you better.
  • Please let me know the product# of the unit.
  • This could be a hardware issue with the computer and we need to isolate it correctly. In the meantime, please perform a hard reset first. Steps:
  • Power down the computer and unplug the charger. Then remove the battery only if it is a removable one.
  • Hold down the power button of the unit for 15 seconds to discharge static electrical charges inside the machine.
  • Replace the battery and reconnect the charger and try to power on the unit.

Please visit these links for further troubleshooting.

Please update the bios from http://ho.com/drivers

Laptop won't recover from Sleep mode

Thanks for your reply.  The product number is VU586UA#ABA.

 

While I'd removed the power and battery in trying to recover from the problem, I'd done so only for about 5 sec's and did not hold the power button down.  I did as you suggested, and for a bit it seemed like that had fixed the problem.  I put the computer into sleep mode a few times and each time I was able to wake it up successfully.  However when I left it in sleep mode overnight, as before sometime during the night it woke up (HP logo on the cover lit, fan running, etc.).  The next morning I tried pressing keys, momentarily pressing the power button, etc., all to no avail.  I noted that the scroll light was turned on, and that pressing the scroll key had no effect.  I held down the power key to shut the computer off, and when I tried to start it again, as before, it went into a mode where the scroll and caps lock lights blinked on and off, but nothing more happened.  As before, I was obliged to remove ac power and battery for a few seconds before I could successfully restart the laptop.

I've now tried it a second time, a day later, with the same results.

Laptop won't recover from Sleep mode

Hi @coffent,

 

I read your post and thanks for your response. Great job trying these steps out. Have you tried out all the steps from the link that I sent? If you have, then please try these steps out and check how things work.

 

  • Open windows Control Panel, open Power Options and next to your currently selected power plan, click Change plan setting.  In the following window, click Change advanced power settings.  In the next window, open up 'Wireless Adapter Settings' and then open up 'Power Saving Mode'.  Next to On battery: click the current setting and a drop-down box will appear - select 'Maximum Performance'.  Do the same for Plugged in.  Then click Apply and Ok to save these settings.

 

  • Also open device manager. Go to Network adapters and expand it. Select the wireless network adapter for your device by right-clicking on it and clicking on properties. Then go to power management option and uncheck the box that says” Allow the computer to turn off this device to save power. Also, check the box that says “Allow this device to wake the computer”
  • Go to control panel>All control Panel Items>power options>edit (change) Plan settings> under turn off display change the time to 30 minutes or more and under put the computer to sleep change it to 30 minutes or more.
  • Under "change advanced power settings"> select "High performance "option from the drop down.
  • Please also check the sleep option and change the time on it. Besides, check all the individual power settings for each component and application listed there.
  • Click the Screen Saver tab, then the Power button in the lower-right corner. Click the Advanced tab. Select an option from the "When I close the lid of my portable computer" pull-down menu.Please change your power setting to maximum performance.
  • You could also try a system restore if the issue has started only recently to an earlier date before the issue occurred.

Link for system restore: http://support.hp.com/us-en/document/c01835735

Please update the bios and chipset drivers  from this link: http://hp.com/drivers if it hasn't been done before.

 

As a last resort, please backup all your important information and perform a complete system recovery to factory settings from this link:  http://support.hp.com/in-en/document/c01867418

 

Hope this helps and your computer works great without hassles.

 

 

To simply say thanks, please click the "Thumbs Up" button to appreciate my efforts to help. If this helps, please mark this as “Accepted Solution”.

 

Take care now and do have a blessed week ahead.

Laptop won't recover from Sleep mode

Thanks for your futher suggestions.  I have tried the suggestions in the 3 links you previously sent.  None worked, for various reasons.  (The Power Troubleshooter made irrelevant & unwanted changes to my power management scheme; there was no "Change settings" button for mice; clicking the "Change settings" button for the keyboard did *not* show a power management tab.)

 

Re your latest suggestions:

 

#1:  I checked Wireless Adapter Settings and battery was set on Medium, plugged in was set on Max Performance.  However the problem occurs even when the computer is plugged in.

 

#2:  I don't understand why you suggest I *check* a box saying "Allow this device to wake the computer" when in fact the computer wakes when I don't want it to.

 

#3:  I have had sleep time set to 30 minutes & the problems still occurs.

 

#4:  Yes, I can get rid of Sleep problems by selecting a power management mode where the computer never sleeps, but that's not the solution I want.

 

#5: Sleep option times are set as I want.

 

#6:  See reply to #4

 

#7:  There are really two problems:

           (1) The computer wakes from sleep mode - this has always occurred, both before and after I did a full factory restore after the hard disk failed.

           (2) After unexpectedly waking from sleep mode (problem #1), the computer goes into limbo and can't be operated until power and battery are removed.  This has started occurring only after the full factory restore.

 

Finally, some further observations:

 

(a) The problem occurs only after the computer has been in sleep mode for several hours.

(b) In the "limbo" state the Scroll light blinks on & off - is this a code for something?

(c) After an attempted restart (after the limbo state but before removing the battery), the Scroll and Caps Lock lights blink on and off - is this a code for something?

 

Any further suggestions are welcome.

Laptop won't recover from Sleep mode

Hi @coffent,

 

You've done brilliant troubleshooting. I have no words to describe the extensive and copious troubleshooting that you've done and kudos to you for that. Some of the steps were tried to ensure that the notebook does not go to sleep to isolate the issue further which has been corrected by you later. Brilliant job! Kudos to you on such brilliant troubleshooting You've also done a bios update, a system recovery and checked all the possible power plans. If you've not run all of Microsoft windows updates, Please perform these updates and check. 

 

If the issue persists, I request you to contact HP phone support to get the unit serviced as it looks like a hardware issue with the computer.

 

 

  HP Technical Support can be reached by clicking on the following link:

(3) Once completed click the 'Show Options' icon on the bottom right.

(4) Lastly, scroll down to the bottom of the page and select 'Get phone number.' A case number and phone number will now populate for you.

 

 

 

I genuinely hope the issue gets resolved and the computer works great without hassles. Trust me I've done all I can to help.To simply say thanks, please click the "Thumbs Up" button to appreciate my efforts to help. If this helps, please mark this as “Accepted Solution”.
