Startup issue: continuous power on - power off after succesful fan cleaning

ENVY DV7 7260 eb
Microsoft Windows 10 (64-bit)

Hi,

 

Having a 90B error (fan having troubles) prior to booting up the system, I consider it a good time to clean the fan.

 

So I completely dissassembled the laptop down to the fan to remove dust. This in order to have less sound and less heat. After reassembling it back to its original state, my laptop started with two errors. Firstly one I cannot remember (skipped to fast) and secondly the recurring 90B error. But skipping those the system started up and everything worked. The laptop was running slowly but I thought it was normal behavior.

 

The day after, my laptop wouldn’t startup. I’ve pressed the start button and the lights went on of both the start button and speaker on/off. Immediately after that it shut down and started back up, producing a startup loop as long the laptop is feed by power (battery or charger).

 

Anyone can help me out? If further details are needed, I will certainly provide those.

 

Kr,

JeromeBertrem

Hi @JeromeBertrem,

 

Thank you for showing your interest in HP Support Forums. It is a great place to find the help you need, from other users, HP experts, and other support personnel. For you to have the best experience on the HP forum, you could also visit our HP Forums Guide for First Time Here?

As I understand the computer is powering on, however, doesn't boot into windows, And it turns off after a few seconds after it's turned on,

 

Please try these steps here:

 

Perform a Hard Reset

 

If the computer still turns off every few seconds, try with an alternate adapter and/or remove the battery and try turning on the computer without the battery,

only connect the adapter and start, let me know if that works.

 

Please follow the steps suggested in the guided troubleshooter - No Power or No Boot Troubleshooting

Hi @kaykaynagele1,

 

Thanks for replying,

I appreciate your time and efforts,

 

I understand you are unable to boot into windows anymore, it's good that you contacted us we will guide you through the right path and since it's under the warranty we'll repair it free of charge if my steps don't resolve your issue.

 

Run the system diagnostics as well as extensive test on the hard drive and memory from F2

 

Depending on the test results, If all the test passes, you could once again try to perform system recovery use the partition available on the PC, Doing this will wipe off everything from the computer and set it back to the original factory conditions, if for some reason you are unable to perform system recovery, this means either the partition is corrupted or system file is missing.

 

The only other way to install Windows would be to order the recovery media for your laptop and using the recovery media you can install Windows. You can check if the recovery media is available online on www.hp.com/drivers by entering the exact model no. of your laptop. To find the exact model no. click here: http://hp.care/2bygf7l

 

Otherwise, you could also reach HP phone support to order the recovery media. Please fill in the product details to get the tech support number.

 

Please use the following link to create yourself a case number, then call and it may help speed up the call process:

Step 1. Open link: www.hp.com/contacthp/

Step 2. Enter Product number or select to auto detect

Step 3. Scroll down to "Still need help? Complete the form to select your contact options"

Step 4. Scroll down and click: HP contact options - click on Get phone numberCase number and phone number appear.
