This is really frustracting, i always felt that the dell laptop inspiron 5548 is too slow while booting and shutdown and opening browsers , office applications etc. Really fedup with this Dell laptop's. Now i regret to buy this kind laptops with the price above 50K.
If any of your dell members please give some solutions regards this.
Apologies for your computer booting too slow. If you haven't already done it, run your virus removal program and make sure you don't have a virus or something else. You may want to run a defrag and disk cleanup. Next check your start up programs and delete those that aren't needed. If none of that is working, then you may need to back up your data and do an OS reinstall.
