  • CPU clock scales down so computer is unusable after switching to battery

    - by Ryan
    When I am plugged in my laptop runs great however when I unplug it and I'm on battery power my CPU clock speed scales down pretty much all the way. I know this is happening by monitoring the clock speed. When plugged in it will usually stay between 1000MHz and 3000MHz but when I unplug it it quickly scales down to less than 500MHz and will get as low as 100MHz and it will NEVER scale up at all on battery power. After I plug the power back in it will then begin operating normally in about a minute. I have tried setting the MIN and MAX CPU performance in power options to 100% and have tried messing around with cooling settings which seemed to be a problem with HP laptops. I have a Toshiba Satellite M500-ST6444 running Windows 7. The BIOS is up to date. I have tried two versions.

  • Prevent runaway threads and ultimately physical overheating and battery drain on Android [migrated]

    - by foampile
    I was wondering if there is a system monitor app that will raise (audible) alerts and offer app closure if it detects runaway threads on Android that cause physical overheating and battery drain. E.g., I just had to turn my phone off because there was a runaway thread that I think was constantly trying to refresh FB where there was very poor connection, so it was going in a virtually endless loop. But I get that with other apps too and not just Facebook. I'd like to actually shut apps down when they're detected. I am not kidding, I nearly burned my fingertips when I touched my phone -- it was on for only 2 hrs and the battery was almost dead. It is because 4G is very poor inside my office building and I checked Facebook walking between my vehicle and the building this AM. After that, the app kept trying to refresh continuously without success and overheating the phone.

  • How does VirtualBox's memory usage work?

    - by DrFredEdison
    I've been running several VM's with VirtualBox, and the memory usage reported from various perspectives, and I'm having trouble figuring how much memory my VMs actually use. Here is an example: I have a VM running Windows 7 (as the Guest OS) on my windows XP Host machine. The Host Machine Has 3 GB of RAM The Guest VM is setup to have a base memory of 1 GB If I run Task Manger on the Guest OS, I see memory usage of 430 MB If I run Task Manger on the host OS, I see 3 processes that seem to belong to VirtualBox: VirtualBox.exe (1), using 60 MB of memory (This one seems to have the most CPU usage) VirtualBox.exe (2), using 20 MB of memory VBoxSvc.exe, using 11.5 MB of memory While running the VM, the Host OS's memory usage is about 2 GB When I shut down the VM, the Host OS's it goes back to memory usage goes down to about 900 MB So clearly, there are some huge differences here. I really don't understand how the GuestOS can use 400+ MB, while the Host OS only shows about 75 MB allocated to the VM. Are there other processes used by VirtualBox that aren't as obviously named? Also, I'd like to know if I run a machine with 1 GB, is that going to take 1 GB away from my host OS, or only the amount of memory the Guest machine is currently using? update Somene expressed distrust over my memory usage numbers, and I'm not sure if that distrust was directed at me, or my Host OS's Task Manager's reporting (which is perhaps the culprit), but for any skeptics, here is a screenshot of those processes on the host machine:

  • Laptop screen turns off on removing power cord

    - by YatharthROCK
    After a recent upgrade to Windows 8.1 Pro from W8, my laptop's screen turns off as soon as you remove the power cord. It turns back on with no issues when you plug the power back in. Keyboard and mouse input is processed while the screen is off. My settings tell the screen to go off after 2 minutes of inactivity on battery. I was having a battery issue from before where my laptop would should down after 5 minutes of running on battery (despite showing 60% left), but I think that's unrelated. Any other info will be provided on request. Can anyone help me figure out what's going on? How can I stop this behaviour?

  • Why does 12.04 upgrade abort with out of space error when I have lots of it?

    - by Kristian Thomsen
    When upgrading Ubuntu from 11.10 to 12.04 I discovered an unexpected problem. The upgrade was stopped because there wasn't enough free space for the installation. I managed to free some space and do the upgrade but now a prompt appears after logging in saying I'm out of space. This prompt asks me if I want to examine the problem. The "Disk Usage Analyser" is opened. In the top it says: Total filesystem capacity: 47.0 GB (used: 13.5 GB available: 33.4 GB) Folder -- Usage -- Size / -- 100% -- 12.5 GB usr -- 44.8 % -- 5.6 GB home -- 30.3 % -- 3.8 GB lib -- 13.0 % -- 1.6 GB var -- 9.1 % -- 1.1 GB boot 2.5 % 309.5 GB and a lot of small contributors like: etc, opt, sbin, bin etc. I do not really understand this problem since the analyser in the top says that I have 33.4 GB left in this file system. What can I do to make Ubuntu use the remaining space? Running df -i in the terminal gives: Filesystem Inodes IUsed IFree IUse% Mounted on /dev/sda7 610800 576874 33926 95% / udev 213451 563 212888 1% /dev tmpfs 218524 486 218038 1% /run none 218524 3 218521 1% /run/lock none 218524 7 218517 1% /run/shm /dev/sda8 2264752 16371 2248381 1% /home The output of df -h Filesystem Size Used Avail Use% Mounted on /dev/sda7 9,3G 7,8G 1,1G 88% / udev 993M 4,0K 993M 1% /dev tmpfs 401M 884K 400M 1% /run none 5,0M 0 5,0M 0% /run/lock none 1003M 152K 1002M 1% /run/shm /dev/sda8 35G 4,0G 29G 13% /home /dev/sda2 101G 64G 37G 64% /media/A2C8E28BC8E25CD3 Running sudo fdisk -l gives Disk /dev/sda: 160.0 GB, 160041885696 bytes 255 heads, 63 sectors/track, 19457 cylinders, total 312581808 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000080 Device Boot Start End Blocks Id System /dev/sda1 63 96389 48163+ de Dell Utility /dev/sda2 * 98304 210434488 105168092+ 7 HPFS/NTFS/exFAT /dev/sda3 210436094 312576704 51070305+ f W95 Ext'd (LBA) /dev/sda5 306279288 312576704 3148708+ dd Unknown /dev/sda6 210436096 214341631 1952768 82 Linux swap / Solaris /dev/sda7 214343680 233873407 9764864 83 Linux /dev/sda8 233875456 306278399 36201472 83 Linux Partition table entries are not in disk order

  • Ubuntu One has high CPU usage but no syncing

    - by Peter
    over the weekend I updated my computer to Windows 8. So far Ubuntu One was running smoothly, but ever since the update (clean, new install) Ubuntu doesn't sync any more. In Windows 7 it would start to sync at full internet speed as soon as I drop a file. But now in Windows 8, as soon as I drop a new file into the Ubuntu One folder, CPU usage goes up to about 50 % and no network traffic occurs. This stays like that for a couple of minutes, CPU usage goes back to normal and then the client says that all is in sync - which isn't true. Is it too early for Windows 8? Do others have the same problem or is there something I can do about it? I try a couple of different things, and realized that if the file size is 20 MB the files get uploaded. The original file was 1.5 GB. I also didn't work with 200, 100 and 50 MB large files. But even with 20 MB large files, the upload is very slow and not steady. The log give plenty of this error: - twisted - ERROR - Failure: exceptions.TypeError About which I don't know the meaning. By the way, the account works just fine on the Ubuntu 12.04 partition. Any help is greatly appreciated. -Peter

  • SQL SERVER – SSMS: Memory Usage By Memory Optimized Objects Report

    - by Pinal Dave
    At conferences and at speaking engagements at the local UG, there is one question that keeps on coming which I wish were never asked. The question around, “Why is SQL Server using up all the memory and not releasing even when idle?” Well, the answer can be long and with the release of SQL Server 2014, this got even more complicated. This release of SQL Server 2014 has the option of introducing In-Memory OLTP which is completely new concept and our dependency on memory has increased multifold. In reality, nothing much changes but we have memory optimized objects (Tables and Stored Procedures) additional which are residing completely in memory and improving performance. As a DBA, it is humanly impossible to get a hang of all the innovations and the new features introduced in the next version. So today’s blog is around the report added to SSMS which gives a high level view of this new feature addition. This reports is available only from SQL Server 2014 onwards because the feature was introduced in SQL Server 2014. Earlier versions of SQL Server Management Studio would not show the report in the list. If we try to launch the report on the database which is not having In-Memory File group defined, then we would see the message in report. To demonstrate, I have created new fresh database called MemoryOptimizedDB with no special file group. Here is the query used to identify whether a database has memory-optimized file group or not. SELECT TOP(1) 1 FROM sys.filegroups FG WHERE FG.[type] = 'FX' Once we add filegroup using below command, we would see different version of report. USE [master] GO ALTER DATABASE [MemoryOptimizedDB] ADD FILEGROUP [IMO_FG] CONTAINS MEMORY_OPTIMIZED_DATA GO The report is still empty because we have not defined any Memory Optimized table in the database.  Total allocated size is shown as 0 MB. Now, let’s add the folder location into the filegroup and also created few in-memory tables. We have used the nomenclature of IMO to denote “InMemory Optimized” objects. USE [master] GO ALTER DATABASE [MemoryOptimizedDB] ADD FILE ( NAME = N'MemoryOptimizedDB_IMO', FILENAME = N'E:\Program Files\Microsoft SQL Server\MSSQL12.SQL2014\MSSQL\DATA\MemoryOptimizedDB_IMO') TO FILEGROUP [IMO_FG] GO You may have to change the path based on your SQL Server configuration. Below is the script to create the table. USE MemoryOptimizedDB GO --Drop table if it already exists. IF OBJECT_ID('dbo.SQLAuthority','U') IS NOT NULL DROP TABLE dbo.SQLAuthority GO CREATE TABLE dbo.SQLAuthority ( ID INT IDENTITY NOT NULL, Name CHAR(500)  COLLATE Latin1_General_100_BIN2 NOT NULL DEFAULT 'Pinal', CONSTRAINT PK_SQLAuthority_ID PRIMARY KEY NONCLUSTERED (ID), INDEX hash_index_sample_memoryoptimizedtable_c2 HASH (Name) WITH (BUCKET_COUNT = 131072) ) WITH (MEMORY_OPTIMIZED = ON, DURABILITY = SCHEMA_AND_DATA) GO As soon as above script is executed, table and index both are created. If we run the report again, we would see something like below. Notice that table memory is zero but index is using memory. This is due to the fact that hash index needs memory to manage the buckets created. So even if table is empty, index would consume memory. More about the internals of how In-Memory indexes and tables work will be reserved for future posts. Now, use below script to populate the table with 10000 rows INSERT INTO SQLAuthority VALUES (DEFAULT) GO 10000 Here is the same report after inserting 1000 rows into our InMemory table.    There are total three sections in the whole report. Total Memory consumed by In-Memory Objects Pie chart showing memory distribution based on type of consumer – table, index and system. Details of memory usage by each table. The information about all three is taken from one single DMV, sys.dm_db_xtp_table_memory_stats This DMV contains memory usage statistics for both user and system In-Memory tables. If we query the DMV and look at data, we can easily notice that the system tables have negative object IDs.  So, to look at user table memory usage, below is the over-simplified version of query. USE MemoryOptimizedDB GO SELECT OBJECT_NAME(OBJECT_ID), * FROM sys.dm_db_xtp_table_memory_stats WHERE OBJECT_ID > 0 GO This report would help DBA to identify which in-memory object taking lot of memory which can be used as a pointer for designing solution. I am sure in future we will discuss at lengths the whole concept of In-Memory tables in detail over this blog. To read more about In-Memory OLTP, have a look at In-Memory OLTP Series at Balmukund’s Blog.

  • APC ups es 700 randomly overload

    - by Matteo Mosca
    First of all, I live in Italy, Europe, so keep this in mind for Volt/Watt considerations. Standard voltage in Italian apartments is 220V. In my living room I have 2 APC ups, one being an ES-550 and the other an ES-700 They each have 4 slots for surge protection only, and 4 slots for surge protection + battery backup. Just to give all the information, they both got their battery replaced less than one month ago. The ES-550 works fine, without any problem. On the battery I have connected: Pc Monitor Sony Bravia 46'' 4th slot is empty The ES-700 has the following on battery: Xbox 360 Ps3 (standby when not used) Wii (standby when not used) Netgear 8 port switch (always on) Here's what happens: the ES-700, randomly, but mostly at night when I'm sleeping, goes like "overload", with the constant beep. If I try to shut it off keeping the power button pressed, nothing happens. The only thing that works is unplugging random stuff (sometimes unplugging 1 console works, other times I have to unplug all 4 devices). Every time this happens the problem is "real", meaning the 4 devices become unpowered, so it's not just an "alarm no working properly" problem. While I'm sleeping, of course, the power usage is what described on the list, 2 devices on standy, 1 off and 1 on. Today it happened again while I was playing with my Ps3. I unplugged it, problem went away. I plugged it again, and it kept working fine. I just can't figure out what's the problem. The only additional info I can provide is that this behaviour started after a big power outage last december 26 (a blackout that lasted almost all day) but the "surge protection" part of those UPS should be there for those problems, to leverage peaks when power goes away or gets restored. Another funny thing is, althought it might not be related, for a couple of days after that event the Wii was unable to power on, I thought its power transformer was broken, but then it suddenly started working again. I can be sure it's not the Wii overloading the UPS because the overload happens even if I leave the Wii unplugged. Any suggestion is really appreciated, and I can provide any additional info, if needed, that didn't come to mind right now. Thanks.

  • Advantages of a 130W vs 90W ac adapter?

    - by David
    I purchased a Lenovo T420S laptop with a 90W/20V AC adapter P/N 42t4426 through my IT department. Subsequently, I ordered a replacement adapter and received a 135W/20V AC adapter P/N 45N0054. The 135W version is about twice as big and heavy as the 90W version. Is there an advantage to the 135W version like faster battery recharging? Are there any negative effects (other than weight), like reduced battery life?

  • What is it that kills laptop batteries?

    - by Mala
    There are many superstitions on what you must never do lest your battery become worthless - and by worthless I mean hold about 16 - 24 seconds of charge. This has happened to every laptop I have ever owned, and I just got a new one, so please help me sort out fact from fiction. Here are some of the things I've heard: Do not keep your laptop fully charged. You must run it completely down every so often. Do not use your laptop plugged in to the wall. Only plug it in when it needs charge. If you will not be using your laptop for a long period of time, don't leave it at full charge. Do not leave your laptop running 24/7. The first two I know to be complete fiction: this was true of old batteries such as you might have had in an iPod in 2003, but modern batteries function better when kept at or near full charge. Devices even have circuitry to prevent you from completely depleting your battery, as this is dangerous. The third point sounds probable, and I'd be interested to know if it was true. However, it doesn't really apply to me because I'm not really the type to leave my laptop alone for a day, much less a "long period of time" The fourth seems most likely of the above, but only because of causality: I have always done this, and my batteries have always crapped out on me. I've generally treated a laptop like a desktop with a battery backup, and that I can move from one room to another if necessary. The fact that my batteries tend to last less than 30 seconds has further entrenched this behavior. Should I be trying to break this habit? Are there any other things that ruin laptop batteries? I love that I can actually use my new laptop unplugged :) I'd like to keep it that way. Update: Additional question: If the computer will be used for an extended period of time plugged in, does it make sense to remove the battery first? Update 2: I know people with laptops older than mine, who actively use their laptops as much as I do, and their batteries still hold about an hours' charge while mine holds less than 30 seconds, hence my belief that something I'm doing kills them.

  • High CPU usage with Team Speak 3.0.0-rc2

    - by AlexTheBird
    The CPU usage is always around 40 percent. I use push-to-talk and I had uninstalled pulseaudio. Now I use Alsa. I don't even have to connect to a Server. By simply starting TS the cpu usage goes up 40 percent and stays there. The CPU usage of 3.0.0-rc1 [Build: 14468] is constantly 14 percent.

UPDATE: Thanks to nickguletskii's link I googled for "alsa cpu usage" (without quotes) and it brought me to a forum. A user wrote that by directly selecting the hardware with "plughw:x.x" won't impact the performance of the system. I have selected it in the TS 3 configuration and it worked. But this solution is not optimal because now no other program can access the sound output. If you need any further information or my question is unclear than please tell me.

  • Comparison of languages by usage type?

    - by Tom
    Does anyone know of a good place to go find comparisons of programming languages by the intended platform/usage? Basically, what I want to know, is of the more popular languages, which ones are meant for high level application development, low level system development, mobile development, web, etc. If there's a good listing out there already, I'm not finding it so far. Does anyone know of a place that would have this? Thanks.

  • Ubuntu 14.04 has a bunch of old kernel directories

    - by NoBugs
    I saw in Disk Usage Analyzer I have 3.13.0-xx for 8 minor versions of the kernel in /lib/modules. Each is around 200MB. I remember having to go through in Synaptic and remove those old Linux versions before, but hasn't this bug been fixed? Is it just paranoid default setting, that perhaps all of the last half dozen kernels might become unbootable, so it keeps each old one around? Or do I have some developer setting enabled by accident that causes this?

  • Nautilus statusbar visibilty - Quickly check free space

    - by Jeremy
    In prior versions, I would open Nautilus and check the statusbar, which would tell me how much free space there is. Now, the statusbar isn't shown by default. I know you can enable it from the View menu, but 99% of users won't do that (and I'd rather not do that, if possible). So, is there some new recommended way to keep tabs on hard drive usage? Or is there maybe some other method that I should have been using in the past but never noticed?
