Tip & How-To about Computers & Internet

Looking for the longest battery life laptop ?

We’ve yet to see a Windows laptop with battery life longer than 5~7 hours, unless we add an extended battery to the system. But when hpand dell launched its new series of laptops last week, one big push wasfor longer battery life.

When you purchase your notebook, charge the battery to 100 percent,discharge it completely, and then fully charge it to 100 percent againto help the battery remember exactly how much electrical charge it canhold. From then on, you’ll never need to completely discharge the laptop battery again, but always make sure when charging it that you let it reach 100 percent. DeHoop told us to “remember to plug in the laptop AC adapter(or dock/port replicator) whenever you get a chance. Most notebookswill recharge quickly.” Salinas had another tip for your batteries:“Keep them cool. Exposure to high temperatures can be a battery’s worstenemy,” he said

Hope the list can give you some help when you purchase a laptop or battery:

how to enable bluetooth


Your computer has to have a bluetooth radio. You can check
Control Panel > System and Security > Device Manager
Do you see a Bluetooth Radio listed?

If not, you don't have BlueTooth on your computer so you will have to add a BlueTooth device by plugging one into a USB port.

If you have a BlueTooth radio, go to Control Panel > Hardware and Sound > Device and Printers > Add a Bluetooth Device

This option is used to connect a blue tooth device (e.g. bluetooth headphons) to your laptop through your bluetooth radio.

See this Windows web page for more information.
Set up Bluetooth enabled device

I will respond to any additional questions you have.

Here are my recommendations for this issue:

1. Reseat the battery.
2. Remove All External Components
3. Check the battery connectors on the battery and the system. Examine the connector on the battery and the system. Make sure that there is no physical damage and that it is clear of debris.
4. Remove All External Components
5. Try a known-good battery in the system, if available.
