It is common for laptops to throttle processor performance if a severe drain on the battery is detected. In this case, it may be that there is something wrong with the battery and it needs to be replaced (it is close to 6 years old, after all). Before spending money on a new battery, I would talk to Dell Support and verify that my conclusion is correct.

Hope this helps,



P.S. You can answer in Spanish if that's the most comfortable; we have translators we can use to read them. Bear two things in mind, however:

  1. The translators are not perfect and terse responses can sometimes be problematic, so be verbose and explain everything very well.
  2. We cannot translate text included in pictures, so either provide english-only versions of these pictures or transcribe the text from the pictures into the body of the message so it can be translated.

now it happens all the time , i have unplug the battery and now it is working with the charger and it is blocked at 1,38 ghz

Try running something like ThrottleStop and see if you can figure out what is causing the throttling.
