I have asked to look at the above, which sort of runs, but in treacle
mode. Takes forever to boot up, press a button and it will maybe respond 5 minutes later. It has Win10 installed on it, it seems to have a reasonable spec. I'm wondering if there should be a recovery CD for it, or if anyone knows where I could download from and burn a CD? |

It should not be that slow then, unless its got a disc full of crap. Difficult to tell, its so slow it doesn't allow you too investigate what's on the HDD. |

It was crawling to the point of logging in, but I have managed to sort that out using a rebuild from the hidden partition. Unfortunately it didn't do a restore to factory and left the following rubbish in place and loading. It loads various things when booting, including Premier Systems, Winzip Driver and Webdiscover - grinding to almost an halt in the process. It becomes so slow, it is impossible to use control panel to be able remove them. I seem unable to do a safe boot, or maybe I don't know how... |

Unfortunately I cannot find the web page I used to disable a lot of Win10 eye candy features. It did include deleting some of the pre-installed MS programs (or apps as they like to call them now) Things like their news app which has an animated icon and in reality is constantly trying to download news from the internet in the background. There are few more apps like this which may not be required. There is a lot of graphic features that can be disabled in favour of performance, especially on an older machine It may also be worth running a cleaner/optimisation program such as CCleaner (free trial) https://www.ccleaner.com/ccleaner/download Is there more than one real time virus checker running? If so they may be fighting each other in that they are both constantly checking any files each of the other checker may be creating. Win 10 comes with an inbuilt virus checker but PC manufacturers are fond of bundeling another. A second virus check could be put into manual mode and removed from the startup list to see if it improves Win 10 performance. -- mailto : news {at} admac {dot} myzen {dot} co {dot} uk |

Well it should be faster than mentioned though. One thing to watch out for
on these cheaper machines is a terribly small hard drive. This often means that when you get a new version of windows as you do every 6 months or sooner, there is just not enough space to actually properly install and configure it. Its probably OK for simple word processing,email or browsing text only sites using the new Chrome Edge. Brian -- ----- -- This newsgroup posting comes to you directly from...

I have managed to run the recovery utility and its faster initially then gradually comes to a complete stop. It has a few unnecessary things on it, which are grabbing memory and CPU, but I have been unable to stop or delete them so far. |

Not malware exactly more demoware when you buy them these days. The first
thing any new user should do is strip it back to the core stuff, then install what they want.

Why do machines with fast multi-core processors end up being unbearably slow? The reasons must be known and easily fixable. Run a copy of Process Monitor and find out. On occasion, I've seen *10,000* registry accesses per second. They repeat at 1 second intervals, some of these things. Even when the registry is cached in RAM, this can't be good. These have *nothing* to do with what you see on the screen. Think of this as a "tax" you pay for modernity. You don't really know how "busy" these newer OSes are, until you look under the hood. ******* Let's look at the B50-30 https://www.notebookcheck.net/Lenovo....123805.0.html Processor Intel Celeron N2815 $107 tray price Bay Trail 2 Core (no hyperthreading), 1.86GHz Likely thermally limited. If no fan is present, will throttle. Memory: 2048 MB (up to DDR3L 1066, OK) "55.86%: Such a bad rating is rare. There exist hardly any notebooks, which are rated worse." === notebookcheck rating https://ark.intel.com/content/www/us...-2-13-ghz.html Cache = 1MB ("I'm not dead yet"...) # Only an issue when running 7ZIP compression # Doesn't say what the L1 uses, which could be an issue Max # of Memory Channels 2 # Means the memory bus is not gimped! # This is important for snappy graphics # (like if you unplug a DIMM) Processor Graphics = "Intel HD Graphics for Intel Atom Processor Z3700 Series" This is a 4 E.U. GPU as the built-in graphics. https://en.wikipedia.org/wiki/Silvermont Scroll down the list here for Execution Units, and see just how low this is. https://en.wikipedia.org/wiki/List_o...ocessing_units 8,10,12,24 The above is pretty low, but only needs to be able to composite graphics windows into system memory (as the GPU has no memory of its own). Only games would be horribly gimped. What of Bay Trail. Well, you're in luck, as it's the first generation of Atom to get "out-of-order (OoO) execution". The Atom processors before this generation, were in-order execution, which means in effect that the max number of instructions retired per clock would be a lot lower. In-order execution means the instructions are serialized, with more stalls. https://arstechnica.com/gadgets/2013...-architecture/ In-order execution was selected for the other ones, in the belief that this would reduce power consumption. Which it probably did. In the text here, you can see that Atom wasn't "pure" in-order. It dabbled a bit in OoO. But only a bit. https://www.anandtech.com/show/2493/8 The concern is, does the next one claimed to be OoO also cheat ? That's the $107 question. You could run a bench on this device and find out. Let's just look some up. Single threaded operation is used for a lot of everyday tasks, so we'll use that. Now, I have a 2C 2T (no hyperthreading processor) too, that I'm typing this on, so we can compare to that for fun. https://www.cpubenchmark.net/singleThread.html N2815 1.86GHz (plus turbo) Passmark CPUMark = 455 2C 2T E8400 3.00GHz (no turbo!) Passmark CPUMark = 1218 2C 2T Even though my CPU is 50% faster on clock, it's pretty close to 3X faster. That means the IPC is about 2X better. And more modern processors with the same clock range, would be that much better again on IPC improvements (because they'd include Hyperthreading for 30% more, plus be able to retire more instructions per clock and have fewer bottlenecks). Hyperthreading varies from -5% to +30% or so, and in some cases, it can actually be better to turn it off in the BIOS. Especially if the OS process scheduler is "defective" in some way. I would need to downclock my E8400 quite a bit, to pull neck and neck with the N2815. So low in fact, I might even be below the recommended spec for Windows 10. I have a single core laptop, running Windows 10, and it's no wonder pony either. The Passmark on that one is AMD V120 2.2Ghz (no turbo, single core) Passmark CPUMark = 665 1C 1T and it's still 50% better. Mine is a single core, which means the N2815 is ahead of it (some I/O can run on one core, while a calc runs on the other core, for example). I put an SSD drive in the laptop, and well, that's a joke. It boots faster, but after that, it's a wash. The chipset is only SATA II. You could disable Windows Defender and get some of the performance back. But is it worth doing that ? You decide. Windows maintenance functions will not run on all cores, and the maintenance is limited to using fewer cores so something is left for the user. There is Windows Defender and there is Search Indexer, wasting performance that could be used reading the newspaper. My laptop is also not running 1909 at the moment, and is using an older version of Windows 10. You can also rip Windows Update out of it, as an option. What fun. There's a lot of fun to be had. Between TrustedInstaller and wuauserv, they waste a lot of cycles during updates. Even checking for updates wastes cycles. Which is better, an unpatched, exploit-riddled older OS that runs at a decent speed, or a bloated over-patched modern OS ? Good question. How lucky do you feel ? For best results, Windows 7 is recommended, just so there is a choice amongst web browsers. And there's DXVA2 so the movie decoder works. (This assumes the 4 E.U. graphics *has* accelerated movie decoding.) I'm surprised they charge $107 for that processor. Of course, they charge $350 for some laptop processors, and we pay a rather large premium for such things. Paul |

There is a party trick I have seen some of these play where they throttle back to a very low clock speed all the time. Going into the BIOS and resetting to default BIOS settings will fix that one. (might also be worth checking for BIOS upgrades while you are at it). Having said that, its a slow machine to start with. About the only thing you can do to make any real difference would be to clone the HDD onto a SSD. It has Win10 installed on it, it seems to have a reasonable spec. I'm wondering if there should be a recovery CD for it, or if anyone knows where I could download from and burn a CD? It will have a recovery partition. So you can recover to the supplied image (which is unlikely to be Win 10). Failing that you can download Win 10 from MS - just search for download Win 10. That will get you the media creation tool which will either upgrade the machine its being run on, or let you write a boot image to USB or DVD. For the utilities etc, there will likely be a tag number of some kind on it that you may be able to use on the Lenovo web site to take you to the right set of utilities. -- Cheers, John. Why do machines with fast multi-core processors end up being unbearably slow? The reasons must be known and easily fixable. Run a copy of Process Monitor and find out. On occasion, I've seen *10,000* registry accesses per second. They repeat at 1 second intervals, some of these things. Even when the registry is cached in RAM, this can't be good. These have *nothing* to do with what you see on the screen. Think of this as a "tax" you pay for modernity. You don't really know how "busy" these newer OSes are, until you look under the hood. ******* Let's look at the B50-30 https://www.notebookcheck.net/Lenovo....123805.0.html Processor Intel Celeron N2815 $107 tray price Bay Trail 2 Core (no hyperthreading), 1.86GHz Likely thermally limited. If no fan is present, will throttle. Memory: 2048 MB (up to DDR3L 1066, OK) "55.86%: Such a bad rating is rare. There exist hardly any notebooks, which are rated worse." === notebookcheck rating https://ark.intel.com/content/www/us...-2-13-ghz.html Cache = 1MB ("I'm not dead yet"...) # Only an issue when running 7ZIP compression # Doesn't say what the L1 uses, which could be an issue Max # of Memory Channels 2 # Means the memory bus is not gimped! # This is important for snappy graphics # (like if you unplug a DIMM) Processor Graphics = "Intel HD Graphics for Intel Atom Processor Z3700 Series" This is a 4 E.U. GPU as the built-in graphics. https://en.wikipedia.org/wiki/Silvermont Scroll down the list here for Execution Units, and see just how low this is. https://en.wikipedia.org/wiki/List_o...ocessing_units 8,10,12,24 The above is pretty low, but only needs to be able to composite graphics windows into system memory (as the GPU has no memory of its own). Only games would be horribly gimped. What of Bay Trail. Well, you're in luck, as it's the first generation of Atom to get "out-of-order (OoO) execution". The Atom processors before this generation, were in-order execution, which means in effect that the max number of instructions retired per clock would be a lot lower. In-order execution means the instructions are serialized, with more stalls. https://arstechnica.com/gadgets/2013...-architecture/ In-order execution was selected for the other ones, in the belief that this would reduce power consumption. Which it probably did. In the text here, you can see that Atom wasn't "pure" in-order. It dabbled a bit in OoO.

Have the Lenovo drivers, etc., been installed? Probably needs Lenovo Vantage installed to do that properly. The process of finding and installing updates usually works fine. It can make a huge difference. |

Before you go there, have you checked to see if there is more than one AV program? Or anything else that looks 'iffy'? A good experiment in these cases is to boot a Linux DVD / USB and just check to see if the machine runs 'normally' (=as expected for the spec). If it does (and I'm *not* advocating installing Linux instead of Windows here g) then you could try creating an additional user, logging out of the std user and logging back in as the new user and seeing if anything has changed. If it has (if it's faster / as expected) then the chances are it's something to do with the std user. If it's not it's likely to be a system problem and depending on how much data and how many 'licensed programs are on there, you may try to fix that installation or just do a fresh one. A std W10 install disk would probably be fine on that and the W10 Media Creation Tool and a 4G USB stick is all you need. https://support.microsoft.com/en-gb/...allation-media You can use the tool to create the image on another W7+ PC (you just need to tell it that's what you are doing) and away you go. If it's already running W10 it should re-authenticate itself automatically when you go online. It might be worth checking what version of W10 (Home / Pro, 32/64 bit) before you re-install (System, General tab). Cheers, T i m |

I have no idea what specific differences there are - but they did say that installing standard and then applying Lenovo updates does NOT have the same effect. (Could have been utter BS.

First thing I'd do is boot it from a lightweight linux distro cd. Running from cd slows any OS down a lot, but not to the extent you describe. If it works that way, as I expect it will, wipe the hdd and install a suitable OS eg a lightweight linux. If you must go windows try an older lighter version.. The problem is most likely malware, so a disc format & reinstall of win10 might be enough, maybe. And for a joke suggestion, win98 runs real fast on modern hardware ![]() NT |
