HP Recommended
HP Pavilion dm4 1055br
Microsoft Windows 7 (64-bit)

Some keys as ENTER, SPACE and BACKSPACE are not working properly in my HP Pavilion dm4 1055br. When pressing one of these keys type two or three characters ( 😞 ENTER (lçj), SPACE (.;M), BACKSPACE (~h). This latter at the same time turn off the F11 key (sound). The light of wireless key (F12) does not turn on. When turn off the F12 key, all the keys mentioned work well.

Dear Professor KNRK

 

The issue still persists. Any external keyboard works fine with my notebook. The keys: arrow up and arrow down, also are not working properly. The arrow up key writes: opU and the arrow down key opens a window preferences of another software linked to the word processor (EndNote). In a spreadsheet, these keys move the cursor in diagonal direction (-45°). All keys work well in the BIOS display. It was restored my system to an earlier date and was restored the computer to its original factory condition by using the Recovery Manager of HP, and the problem persists.

 

Thanks for your support.

According to the message you have recently posted I would like to confirm that this is a hardware issue and the whole keyboard assembly needs to be replaced. I strongly recommend you to Contact HP Technical Support over the Phone for further assistance to get your Notebook diagnosed and serviced by an authorized HP Certified Engineer

 

You can also Check your warranty Here to verify the warranty status
