Hi,

Fan

Fan not operating correctly

90B

The system fan may be malfunctioning. For information on troubleshooting heat-related issues, see Fan Runs Constantly, the PC Operates Slower than Expected and Generates Heat. It is also recommended that you perform a hard reset as that can sometimes restore the system fan to working order. See Use Hard Reset to Resolve Hardware and Software Issues for details. If the system fan continues to malfunction, contact HP support.

Hi,

Wireless Module

Not installed or responding

701

Reseat the wireless LAN adapter module, if your notebook supports it. Because seating or reseating a wireless LAN adapter is unique to each HP notebook PC model, it is recommended that you go to www.hp.com and perform a search using the keywords reseat wireless . When the list of articles appears on the search results page, look for any articles that match your notebook model. Not all notebooks support the ability to remove and/or install a wireless LAN adapter module. If the memory module still fails, contact HP Support.

Hi,

This means that your HDD needs to be replaced.

If your notebook is under warranty please contact HP. They'll send you a new hard drive for free.

How to do it? Check the link below and choose your country:

@kssuarez;

I've been having this problem too. 

I tried a few Factory Rastores, but the problem came back. 

For me, I think the file which allows the computer to boot was damaged. 

I've installed a new copy of Windows 7, and it's all fixed 🙂 

I got told to contact HP about getting a new Hard Drive, they told me it would cost £70 for it. 

The guy on the phone said it probably just needs a new copy of windows 7, and they were going to charge me £80 for that! I'm still under warrantly!

[Daniel_Potyrala]

The 3f0 error is an information that the hard drive will fail soon.

It's strongly recommended to do backup asap and to replace the HDD for new one.

my computer makes me run a start up test which takes about 15 mins or more, after that, my computer works fine...
