My laptop works very slow

posted in: Notebook Very Slow | 49

I have a 3 year old Toshiba Satellite (bought new) series P15-S420. It used to do everything at super speed. Now it is very, very slow! I’ve uninstalled all my heavy programs that I added on (like Photoshop, games, etc…) and there has been no change! My husbands HP has an accelerator control. Does Toshiba have one hidden somewhere? Any ideas and or advice from anyone would be helpful! Again thanks for any and all help.

Usually a laptop works very slow because of the three following problems.
1. Installed spyware or adware programs consume a lot of resources and slow down the laptop. Open up the task manager (right click on the task bar) and check the CPU usage in the performance tab. From my experience, the CPU usage might vary 0-10% when the laptop is idle. If it’s constantly over 50%, then you might have some malicious software installed on your laptop. You can try to clean it with an adware/spyware removal tools, for example spybot. Sometimes it’s very hard to get it completely clean and in this case I would recommend restore the operating system back to original factory defaults. You can restore the factory defaults if you boot the laptop from a recovery CD or DVD. Before you run a recovery CD/DVD, back up all important data from the hard drive because it would be erased and reformatted during the restore process.
2. The heat sink is clogged and the laptop overheats. If the laptop heat sink is clogged, the CPU overheats and it might cause the entire system to slow down. It’s very easy to check the heat sink on Toshiba Satellite P15. It is not necessary to remove the heat sink if you want to clean it up, you just have to remove the fan and clean the heat sink with compressed air.
3. The hard drive is going bad. Turn on the laptop and listen if the hard drive makes unusual noises (clicking, grinding, etc…). It’s possible that a laptop will run slow if the hard drive is bad. In this case you’ll have to replace the hard drive and reinstall the operating system. Sometimes the hard drive might be bad even if it doesn’t make any strange noises. You can test the hard drive with Hitachi Drive Fitness test.

    Dany,

    i have an asus ul30a its a core 2 duo with 3gb ddr3 ram its boots up just fine but afruns really slow i scanned it with avg internet security no viruses or spyware were detected i also tried removing some of my newly installed games or proggrames but its no use it still is slow as a turtle what can i do

    Test the hard drive. You can download and run SeaTools (from Seagate website) or any other hard drive testing utility.
    If the hard drive passes test, most likely it’s time to backup data and reinstall Windows from scratch.

    My Inspiron 1521 laptop one day kept freezing and having error screens and the battery died (so i wiped my computer and installed windows 7 again) but now my computer is really slow but it stopped freezing and getting error screens. I mean everything is slow i can’t even watch videos on the internet without them lagging anymore. Does anyone know what the problem might be and how i can fix my computer.

    (i am suspecting a power surge and if this is the case what would of been damaged?)<- not for sure

  7. i have a acer aspire 5715z it dual core 1.8ghz 358bm 965gm video card and 3 gb ram my laptop boots quickly when i play a game after 30min the laptop works really slow then i shut it down and it doesent start i wait for 5 min and it starts then its does the same thing again why? :(

  8. I too have the same problem as #41.

    Once I pull the power jack from the socket the notebook becomes *really* slow, even for normal day to day things. It’s not a power plan problem as it’s always in maximum performance, and reattaching the power jack doesn’t solve this. The only working method I’ve found is rebooting. Not even shutdown, as it always boots very slow, only rebooting gets it back to the right speed. I’ve also noticed that in Linux, when I detach the power, the screen backlight goes off and never gets on again, so it may probably be a hardware thing. It didn’t do this from the beginning, but some months later. Switching drivers (original, updated) doesn’t do anything.

  9. Hi all
    from about 2 month, my HP HDX 9350 is very slow when i plug the ac adapter, if the nb is on (ie when i unplug ac power to change room, when i reconnect to ac, after few seconds the nb go to be very slowly, if i play a game my fps drop from 50-60 to 1-5) and to solve the problem only thing i can do is restart the system.
    can be a hw problem?
