Performance :: Running Abnormally Slow On Lenovo T420
Nov 12, 2015
I am running Windows 10 Pro for almost 2 months now on my Lenovo T420 laptop. It's been running great until a couple of weeks ago where it dived bigtime in performance. I suspected it was a new 3rd party battery (had been running great for a couple of weeks as well), which was the problem. The battery did indeed have a problem and without AC power, the laptop would at last not even start. I took the battery out completely and started the laptop on pure AC power and it worked great for another week. Now, I have the problem again.
Main symptoms:
- IO 4x less than usual
- Slow reaction on the entire system
- Applications open and perform very poor and slow
- Windows search never opens for example "dxdiag", I have to run this through the "Run" application.
It's running super slow, IO's is 4x of the normal (see attachments). Random IOps have dropped a lot while sequential read/writes is still the same... Task manager is nowhere near busy and I've tried to disable the page file completely. I do have Symantec AV but this is not affecting the performance at all. Tried to run DISM to check for index corruption, all fine. I also suspected the SATA controller (SSD is not bad since I have tested with another one as well, same result) and tried to update the driver, but to no avail.
After the upgrade I performed a "Reset this PC" with "Keep my files". Periodically the WiFi will die. No networks will appear in the list in the pane which appears when one clicks the icon at the bottom right.The fastest way to fix it is to click the left-most button twice, which seems to disable/re-enable and automatically reconnect to the network. I have checked the router. The problem is not manifesting on another Lenovo laptop upgraded the same way. I am using the latest available network driver.So far I haven't performed a clean install due to the time it will take.
I just switched to a new motherboard, its an ASRock H97M-ITX/ac. Before I turned off my pc with the old motherboard I uninstalled some devices like the IDE controllers, network adapters, and sound. Then I installed the new motherboard, turned on the pc and noticed right away it was very slow but after a few restarts and installing the new motherboard's drivers it was somewhat faster but I could tell that it still wasnt right. I ran a benchmark on my ssd and got what I think is a really bad result:
I'm pretty sure this is terrible for a SSD. So I guess I did something wrong. I'm prepared to reinstall Windows, but thought I'd check in here first because it would save some time if I could just fix my current Windows installation. Obviously a clean install would be best but the time involved in getting everything set up again!
Ever since i updated my laptop to windows 10, the fan has been running on full speed and i am not running anything intensive (just Firefox), task manager shows some Microsoft background task host and i really don't want to change back to 8.1.
I'm using an Intel SSD 240GB 520 series. Always loading very fast, i.e., about 8 seconds from cold boot.
Since windows 10 is installed, boot time is about 20 seconds and desktop icons take some time to refresh and load their images.
Regarding the boot time: I've narrowed it down the an unexplained read/write access on my external HDD eSATA which is used for backups, though currently all backup process are stopped.
When I remove / turn off my external HDD, boot time is about 8 seconds. I can't figure out why all of a sudden it required this access to this HDD.
I have a Toshiba Laptop with an AMD processor, 4gb Ram, 500 Gig hard drive with 366gb free. It is running very slow. I have over 70 processes running. I'm pretty sure I don't need that many but I don't know what is needed and what is not. I've tried to copy the list but can't figure out how to do it. I'm using open office.
I've notice that on windows 10 and 8.1, task manager would show the my max cpu core speed is 2.3-2.4 ghz. However, my Core 2 Quad q8400 is rated at 2.66 ghz. I tried changing the power settings in windows and try lowering my cpu temperature, but my speed would never reach 2.66 ghz.
I've had Windows for a few months now and never really had an issue until the past few days. Overall CPU performance/speed is way down. Firefox freezes then recoops every 2-3 minutes, adobe plugin constantly crashing, even to do things offline is crazy slow.
I downloaded Windows Defender probably a week or 2 ago and that is the only big change that I know of done on this computer. I used to run Malewarebytes, SuperAnti-Spyware and Advanced Windows SystemCare. But was told that Advanced Windows SystemCare was the devil and to try TFC (temp file cleaner) & MyDefrag instead. So now i'm running;
Windows Defender MalewareBytes (free) SuperAnti-Spyware(free) TFC MyDefrag
Is this combination making my computer un usable? Or something else?
Ever since I loaded Windows 10 my internet is running slow and I continuously receive either a "recover webpage" message or "stop script" message. I am on IE 11. I tried the new Microsoft Edge but it seemed to run slower than IE. Does any kind of update need to be done to my wireless router. It is a Netgear N750 model #WNDR4300.
After launching Mozilla hard disk activity seems to be permanently on, as if Mozilla where reindexing or something. It takes a long time (10-20 minutes) to stop and it makes browsing a very jerking experience. Of course I did a clean install to rule out some corrupted installation but no dice.
Launching Resource Monitor shows that all disk activity is being done by Mozilla FF and Windows Defender (Firefox being the first candidate).
I have just updated to windows 10 last night and it has been running flawlessly except for the temperature. My GPU idle temp was 37-40 (Windows 8.1) and after upgrading to Windows 10, the idle temp is now 47-50. It really worries me. Gaming temp is still fine.Idle fan speed is 30% (same as Windows 8.1)
Asus UX305F laptop I bought last week. It's working fine apart from a couple of things:
- When the battery is getting low, say from 10% and down, the performance drops dramatically and everything, particularly the internet, runs so slow that it's almost impossible to use until I reconnect the charger. I've changed the on-battery power settings to match the performance settings when it's plugged in and it hasn't made any difference.
- When I'm using the laptop in my bedroom which is adjacent to the living room where the WIFI signal is coming from, the connection is extremely slow, much slower than my mobile phone for example. In the living room I average about 50mbps whereas in the bedroom I'd be lucky to get 20mbps though my phone can get about 40mbps in the same room.
I recently installed Windows 10 on a desktop computer and everything went as smoothly as it could have, with no problems at all. So, motivated by how well everything went with that computer, I decided to upgrade Windows on a laptop as well. The laptop is a Toshiba Satellite L855, with an Intel Core i3-2370M processor.
The upgrade process on the laptop also completed successfully. Now both computers have Windows 10 and so far it has been running... fine.
The only unusual thing I've noticed with the laptop is that the CPU fan wants to run at full speed all the time, even though the computer is never used for any "processor-intensive" tasks. The normal activity on it is browsing the web, watching videos, playing music, writing text files and really nothing more than that.
I immediately found this odd and I have come to the conclusion that something in Windows 10 is responsible because:
a) This never happened in Windows 7, which was the previous operating system the computer had, and
b) This doesn't happen when I start the computer and go into a different operating system, namely Ubuntu.
addressing in order to not lose my data. To give a bit of background, my laptop has 2 internal hard drives, 1 is my main/primary drive which I used for day to day operation and the other was just a backup drive which has a system image of my system.
My main drive failed, and after many horrifying clicking, scratching and high pitch squeals coming from the drive, I can only assume it has failed mechanically and isn't some kind of virus. So now I'm currently left with only my internal backup drive with a system image on it.
I was hoping to use this backup drive as my new primary drive, however I want to keep the files on the backup drive. I checked with my Hirens Boot CD and saw that my backup drive contains everything my other hard drive had, including the operating system contained within the Windows backup folder.
Normally for this I would install windows on another hard drive and then restore my files with the system image. However my laptop doesn't have a system restore disc or a copy of windows, it instead came with partitions on the hard drive which requires erasing my backup and consequently losing all my data.
I finally ask the question, is it possible to use the files currently stored on the backup drive without having to resort to buying a new hard drive to copy the files across and then partitioning my backup drive?
After installing Windows 10 a while back I began seeing a "Your computer is low on memory" error... this error only appears after the computer goes to sleep and is woken up, and never happened on Windows 7 or 8.1. Nothing has changed except for the os
The os is on 250gb ssd with 164gb of free space. I have a second ssd that I install software to (Autodesk, Adobe, etc) and it has over 150 gb of free space. There is a 1tb hd for general storage which has over 500gb of free space
When the "Your computer is low on memory" error occurs windows says it needs to shut down programs to save memory, this causes any program that's open to stop responding and crash. Also, when this happens one of my monitors typically freezes up (usually monitor 2) and the default playback device for my sounds (monitor 3) gets changed and I can't hear any audio until I restart the computer.
After a restart everything seems fine. None of this happened until I installed windows 10...
I have found that my CPU usage is running at 30%, due to Service Host: Local System (15). I have the list of the 15 processes, but how do I find which one is using all the power.
I have a Windows 10 pc I have never had problems with I was playing wow just now and the screen went all black and the computer kept running. The monitor said no connection found despite being connected to the tower that was still running. Naturally I tried restarting the computer manually. Now turning it back on nothing happens; the blue power button blinks orange; and makes a very loud clicking noise. This happens even when the power cord is plug in and you don't touch any buttons. I opened my pc and cleaned the fan still nothing.

So I run the check again with an ISO image of Windows mounted in E, but I got the same error message.

I have a HP Stream 11 laptop I bought from Walmart, it came with Windows 8.1 and I went through the charade of upgrading from 8.1 to 10 so it would validate they key and then I immediately did a clean install. Sadly with this laptop, it only has a 32 GB eMMC drive (non-upgrageable), when formatted it is brought down to 28 GB, after the clean install I was at 15 GB, I have installed very very few and rather lightweight applications that at most take up 1 GB. So left with 14 GB, what I have noticed since then... it seems as the updates rolls out, I'm starting to run out of space, I just did the "November 1511" update and I am now down to 5.75 GB free. Is there anything I can do to slim down Windows 10? or Should I just downgrade to a different OS?
After upgrade to windows 10, tasks still run but don't appear in task scheduler so I can't edit them. Where are they kept? More importantly, how to I get them to show up where I can edit them?
When opening Task Scheduler I get at least 50 boxes I have to close before I can exit the program (or use task manager to do so.)
I'm a huge fan of the Windows 10, I love it, however recently I've gotten my first glimpse of the buggy side. The computer (pretty decent) is taking a very very long time to shut down. I just let it be, maybe update or something, however it kept doing it. After a few days I checked the event viewer, and I had quite a few of errors.
The main error (that I think, I'm no computer expert) that is causing this domino effect is a distributed error, CLSID and APPID. I've tried many solutions out there, and none seem to work.
Upgraded from win 7 Pro x64 to Win 10 Pro 10 days ago,, first week startup was perfect, then something happened, an upgrade or external program, don't know.
Have read in other forums to run DSIM.exe and found some errors, but didn't know what to do..
Normally when i use the net all is fine. Noticed today when i run a video convertor programme in the background the loading of web pages is extremely slow. Stop Freemake video convertor and page loading is normal speed. I assumed it was memory, did memtest and no errors found. CPU monitor sits on 100%. Had similar problem with Villisoft last week. Time for a new CPU methinks but having said that would 100% cpu usage slow down webpage loading to that degree.
I have an HP Envy i7 laptop which came with a 1TB hard drive. As there was space to add a second drive I added a 500GB drive. In addition I added a 320GB drive in the DVD slot (using a dvd/disc converter cartridge).
I have recently noticed that disc access in Explorer has become really slow (seems to think about it for 10 - 15 secs sometimes) and loading programs seems to take longer too.
