I have a Dell Inspiron 1525. I had to reinstall Windows Vista. It has WiFi capabilities. I cannot figure out how to turn it on. The WiFi switch on the right side is turned on.

There should be a switch on the lower right side of the Dell Inspiron. That should click forward and backwards. Clicking it forward "turns it on", Clicking it backwards "turns it off". Let me know if it works!

Since it sounds like an issue with the Power first try to release flea power.Disconnect the charger,remove battery,press and hold down the power button for 30 seconds.Reconnect the battery and charger.Turn on system and check if it turns on. For further help please check Dell Inspiron 1525 Manual. Also confirm if the light on the charger stays on,when connected to the system.

use recovery disk to restore vista. if ur pc had data take ur pc to experts.

dell laptops running in windows xp and vista can install any free software as long the software is windows based like xp and vista.

Boot to recovery console using XP CD, run CHKDSK /R and see if that resolves.
If no go, try a reinstall of windows, if still no go, then replace HDD

Hibernate issues are generally an issue with the Video driver. Try the following: Update to the latest list of drivers from support.dell.com BIOS Video Driver see if the issue is resolved. If not, then try editing the startup group of MSCONFIG and see if an item running at startup is causing the issue. (Start, RUN, MSCONFIG, OK to open MSCONFIG)

Did you turn off the wireless on your laptop?
Fn + F2 will turn on the wireless.
Let me know if it didnt help.
