Here is a problem I\u2019ve not seen before. A Lenovo Thinkpad E530 laptop running Windows 7, which after working fine for months developed a critical problem. On start up the user would see the network icon in the notification area (bottom right) show a busy icon or a red cross. No network connectivity, and the machine almost unusable.<\/p>\n

After around 20 to 25 minutes the network sprang into life and everything was fine, until the next reboot when the problem repeated.<\/p>\n

I fixed several errors in the event log to no avail. The problem persisted.<\/p>\n

Went into msconfig and did the usual trick of disabling all non-Microsoft services and startup items. Everything worked fine. Laptop booted quickly and connected to the network.<\/p>\n

What was the culprit? Trial, error and instinct eventually narrowed it down to an Intel service: Bluetooth Device Monitor. If enabled, 25 minute boot. If disabled, two minute boot.<\/p>\n

I updated the Intel Bluetooth driver, a substantial 300MB download. This fixed it. I noticed that the updated Bluetooth Device Monitor now says it is from Motorola:<\/p>\n

I understand it was always provided by Motorola but previously signed by Intel.<\/p>\n

Posted here in case others run into this issue.<\/p>\n

Update<\/strong>: this seems to be a common problem. It seems that a recent Microsoft update is incompatible with some versions of the Bluetooth driver. See here<\/a> for discussion on the HP support forums, where it has occurred with the HP Probook 4540s and others. <\/p>\n

As noted in the comments, I used Lenovo\u2019s system update utility to grab the more recent \u201cMotorola\u201d driver. It shows there as an optional update. <\/p>\n","protected":false},"excerpt":{"rendered":"
