Question about the accuracy of the Total remaining time for battery in Power Meter

Mr President.

I checked several laptops that are of the same model, one of them cannot display "Total time remaining" in the power meter. Even other laptops may display, but the values are equivocal. Sometimes the 'remaining power' is 80%, but 'Total remaining time' is 1H20Mins. And sometimes, the "remaining power 'is 75% ', but"the Total remaining time"is 1H30Mins.

How Windows calculates the 'Total remaining time? I found what OS will have one or two minutes to display "Total remaining time" after I have the power cable plug-out.

Which is appreciate to get your answer.

The remaining computing power comes from the numere questioning power management drivers and is a fairly complex calculation based on current usage (the amount of energy is consumed), the capacity of the battery (what total capacity is left and how fully charged is battery) and can also vary depending on what else is plugged into the USB port of the computer , what accessories (memory, video card, etc.) are installed, how good or bad, the battery is to maintain a charge and so on.  There is no particular reason to believe that maybe outside the right-out-of-the-box everything two laptops will show the same calculation even if they are all the same brand and model.

  • Question about the Y510 AHCI drivers for install XP

    NiHao Lenovo Forum,

    I am a proud owner of your IdeaPad Y510. I just wanted to ask what the web page offers Lenovo the AHCI storage driver to activate the storage controller SATA on the motherboard for my laptop Lenovo IdeaPad Y510?

    I ask because Y510 as many users who install the XP will need to have these storage SATA controller drivers if they want to support higher speeds, hot plug and native command queuing (NCQ).

    I see that Lenovo provides the following AHCI drivers for ThinkPad found here:

    www-307.IBM.com/PC/support/site.WSS/MIGR-62909.html

    Also, it would be useful to let everyone know that Lenovo Y510 models come with what advice system that they have, with regard to the necessary SATA AHCI Controller driver for them.

    I see the ThinkPad models use Intel 82801GBM SATA AHCI Controller or Intel 82801HEM/HBM SATA AHCI Controller as indicated above from the URL.

    How can I check my Y510 to know what Intel SATA AHCI Controller is necessary here?

    Some clarification would be useful. Thanks in advance for any help and assistance here.

    Also another method here would not create an installation with the Intel Matrix Storage Manager drivers slipstreamed XP disc? And how does a person know which of the many Intel Matrix Storage Manager drivers should be slipstreamed to the pilot Y510 AHCI SATA Controller here?

    And how many different models of Lenovo Y510 uses different system boards? Think there are at least two, because some have been announced with a FSB 800 MHz right?

    Thanks for any help and support here in advance.

    Read the FAQ some might answer your questions.
    Also, I suggest that different motherboards are in different models, as I said there are even different colors - green and Brown motherboards there. Brown, I saw myself - those who are ASUS, green are unknown for me.
    Then, NCQ is not a feature of driver software. It is a material of HARD drive capacity to optimize movement traectory leaders to speed up the read/write process. So, no driver is required to activate. This work iven in the BACK.
    AHCI driver is inside driver chipset. Also, you can integrate it. Please, read the FAQ .

  • A general question about the stylesheet XSL - FO for BI Publisher

    Hello
    Of BI Publisher MS Word Add-in, there is a menu item that allows users to export my. Model RTF as an XSL - FO stylesheet. This provide great flexibility to users so that they can implement the most comprehensive features/features, which are not covered by keys/menus of Word Add-in, on their report. Now my question, how can reuse us this XSL - FO file (.) XML) when we finished editing on this subject? I tried to use the web client BEEP to download as a template of report TONE repository file, but it doesn't seem to work. Could someone give me an idea of this? There must be a way to deploy the XSL - FO stylesheet for model data BEEP otherwise, the item of menu "export" in word add-in becomes meaningless.
    Thank you very much.

    Just download the files you said.

    and click the new button at the top, it will create a new model with the name "new model".
    You have to assign one of the template you downloaded for this report. in this, there is an option as 'TYPE '.

  • Question about the extension of RAM for Satellite A50-522

    Hello

    I have a Satellite A50-522, with a Pentium M 715 @1. 5 Ghz processor and Intel 855GME chipset. To expand its RAM I referred to the Spain/Toshiba support website and I bought the PA3313U-2M1G (1 GB SDRAM 166 MHz DDR333/PC2700) via amazon.com. It turns out that this RAM is for "Alviso chipsets" - which are those relating to the Intel Centrino processors with 9xx series express chipset. I called Toshiba/USA and they recommend the PA3313U-1M1G or its equivalent Kingston KTT3311 / 1 G (since it is impossible to find in the Mexico), instead of the one I already bought. They all seem exactly the same thing in their description, except for the note "alviso chipset.

    My questions are:
    (a) is the chipset of this computer, considered "alviso" type? and
    (b) if not, should I keep the RAM I bought already (PA3313U-2M1G for alviso chipset)?, can I have performance or compatibility problems? What are the risks of the use of this "alviso RAM' in a 'no-alviso chipset? I deeply appreciate your input.

    Thank you!

    Hello

    The RAM modules for especially for chipsets alviso are not known to me, but the Satellite A50-522 certainly supports the memory PC2700 PA3313U-1M1G bar.
    I guess the PA3313U-1M1G and PA3313U-2M1G are the same modules from memory.

    PA3313U-1M1G and PA3313U-2M1G memory module are supported the same specifications of 1 GB - SO DIMM 200 pin - DDR - 333 MHz PC2700

    I think you can use both modules without any problem.

  • Question about the USB wireless adapter for Windows XP

    I'm trying to set up a wireless connection for my desktop pc with Windows XP. I don't see any options for a wireless connection. A USB adapter would do the trick? Looks like the easiest option.

    For a desktop computer with Windows XP, there was probably no built-in wireless card. Some systems Windows XP later had these as optional.

    You must meet your Dell model.

    A USB dongle should work, but make sure there is a Windows XP driver on the suppliers Web site before you buy. Windows XP has reached its end of life and is no longer supported by Dell or, more importantly, Microsoft.

  • Question about the possible television series total bit rate discrepancy

    Hello, I started recently to buy some from Itunes TV shows when I noticed something I was curious about. I noticed that when I look at the "total sampling rate" for none of them via "My TV Shows" in Itunes, they tend to be a little higher than the sampling rate total on the physical files that I have. For example when you look at the an M4V file that is lists the total flow as being '5257' but must I go to my tab TV shows from Itunes and watch the news for that same file, it shows the total flow is "5663." I'm just curious as to why they are apparently different when the size of the two files are apparently identical.

    Also as a note on the side of something else that I've been curious to know is why is the size of physical videos always slightly more small then what is stated on the page of the show? For example, the first episode is 968 MB but the file is only 923, however after that, in the peripheries, it shows (968,071,723 bytes) Does this mean that it is actually the same size, it's just that how M4V are compressed it occupies less space because of its format or something?

    Any help would be appreciated, I'm relatively new to actually buy things via Itunes so I want to just make sure I know all the details, for example I just found out the other day, after downloading an entire show, I had to set it manually to download 1080 p, otherwise you end up with 720 p instead, which means that I had to re - download it all again.

  • Question Basic setting, ask questions about the buffer cache

    Database: Oracle 10g
    Host: Sun Solaris, 16 CPU server



    I look at the behavior of some simple queries that I start the tuning of our data warehouse.

    Using SQL * more and AUTOTRACE, I ran this query two times in a row

    SELECT *.
    OF PROCEDURE_FACT
    WHERE PROC_FACT_ID BETWEEN 100000 AND 200000

    He finds the index on PROC_FACT_ID and conducted an analysis of the range of indexes to access the data in the table by rowid. The first time, that it ran, there are about 600 physical block reads as data in the table were not in the buffer cache. The second time, he had 0 physical block reads, because they were all in the cache. All this was expected behavior.

    So I ran this query twice now,

    SELECT DATA_SOURCE_CD, COUNT (*)
    OF PROCEDURE_FACT
    DATA_SOURCE_CD GROUP

    As expected, he made a full table scan, because there is no index on DATA_SOURCE_CD and then chopped the results to find the different DATA_SOURCE_CD values. The first run had these results

    compatible gets 190496
    physical reads 169696

    The second run had these results

    compatible gets 190496
    physical reads 170248


    NOT what I expected. I would have thought that the second run would find many of the blocks already in the cache of the pads of the first execution, so that the number of physical reads would drop significantly.

    Any help to understand this would be greatly appreciated.

    And is there something that can be done to keep the table PROCEDURE_FACT (the central table of our star schema) "pinned" in the buffer cache?

    Thanks in advance.

    Christopher Curzon wrote:
    Your comment about the buffer cache used for smaller objects that benefit is something that I asked about a good deal. It sounds as if tuning the buffer cache will have little impact on queries that scan of entire tables.

    Chris,

    If you can afford it and you think it is a reasonable approach with regard to the remaining segments that are supposed to benefit the buffer cache, you can always consider your segment of table with 'CACHE' that will change the behavior on the full of a broad sector table scan (Oracle treats small and large segments differently during the execution of table scans complete regarding the cache of) marking stamps, you can override this treatment by using the CACHE. NOCACHE keyword) or move your table of facts to a DUNGEON hen establishing a (ALTER SYSTEM SET DB_KEEP_CACHE_SIZE = ), modify the segments (ALTER TABLE... STORAGE (USER_TABLES KEEP)) accordingly and perform a full table scan to load blocks in the cache of the DUNGEON.

    Note that the disadvantage of the approach of the KEEP pool is that you have less memory available for the default buffer cache (unless you add more memory on your system). When an object to mark as being cached is always is in competition with other objects in the cache buffers by default, so it could still be aged out (the same applies to the pool of DUNGEON, if the segment is too large or too many segments are allocated age blocks out as well).

    So my question: How can I get for a parallel analysis on queries that use a table scan complete such as what I posted in my previous email? It is a question of the provision of the "parallel" indicator, or is it an init.ora parameter I should try?

    You can use a PARALLEL hint in your statement:

    SELECT /*+ PARALLEL(PROCEDURE_FACT) */ DATA_SOURCE_CD, COUNT(*)
    FROM PROCEDURE_FACT
    GROUP BY DATA_SOURCE_CD;
    

    or you could mark an object as PARALLEL in the dictionary:

    ALTER MATERIALIZED VIEW PROCEDURE_FACT PARALLEL;
    

    Note that since you have 16 processors (or 16 cores that resemble Oracle 32? Check the CPU_COUNT setting) the default parallel degree would be usually 2 times 16 = 32, which means that Oracle generates at least 32 parallel slaves for a parallel operation (it could be another set of 32 slaves if the operation for example include a GROUP BY operation) If you do not use the PARALLEL_ADAPTIVE_MULTI_USER parameter (which allows to reduce the parallelism if several parallel operations running concurrently).

    I recommend to choose a lesser degree parallel to your default value of 32 because usually you gain much by such a degree, then you can get the same performance when you use lower a setting like this:

    SELECT /*+ PARALLEL(PROCEDURE_FACT, 4) */ DATA_SOURCE_CD, COUNT(*)
    FROM PROCEDURE_FACT
    GROUP BY DATA_SOURCE_CD;
    

    The same could be applied to the paralleling of the object:

    ALTER MATERIALIZED VIEW PROCEDURE_FACT PARALLEL 4;
    

    Note When defining the object of many operations in PARALLEL will be parallelisee (DML even can be run in parallel, if you enable dml parallel, which has some special restrictions), so I recommend to use it with caution and begin with an explicit indication in those statements where you know that it will be useful to do.

    Also check that your PARALLEL_MAX_SERVERS is high enough when you use parallel operations, which should be the case in your version of Oracle.

  • A few questions about the difference between the Satellite P70, L70, S70

    Hello, I have a lot of questions about the P70, L70, S70 series that come with a 1920 x 1080 panel.

    (1) what are the differences between the L70 and S70 series? With the exception of the RAM and HARD drive capacity, books seem pretty identical.

    (2) P70, L70, S70 doesn't support a 2nd HARD drive or it's just the P70 series that support?

    (3) all the three (P70, L70, S70 series) come with the same TFT panels?

    (4) of the above series, which supports mSata?

    (5) all the model of each series are delivered with support from mSata? For example, it could be that L70 - a - 13 m supports mSata is not the case of the L70-a-146?

    (6) all the foregoing, are delivered with a S - ATA II or III S - ATA interface?

    (7) who is the best of these series listed? I'm trying to understand what makes the big difference of S70 to P70 except for the envelope for example.

    Thank you in advance.

    > (1) what are the differences between the series L70 and S70? With the exception of the RAM and HARD drive capacity, books seem pretty identical.

    What models Sat L70 and S70 do you mean exactly? There are different L70-xxx-xxx and S70 models on the market that supports different hardware specifications.

    (> S70 2) P70, L70, support a 2nd drive HARD or is - it just the series P70 that support?
    As you can see in this [Sam P70 HDD replacement document, | http://aps2.toshiba-tro.de/kb0/CRU3903II0000R01.htm] the P70 series supports the 2nd drive Bay HARD, BUT even if there is a 2nd HARD drive Bay, this does not mean that you can use the 2nd HARD drive. In the case where the 2nd HARD drive Bay are equipped with HARD drive connector, you can use the 2nd HARD drive

    I also found the [Sam L70/S70 HDD replacement | http://aps2.toshiba-tro.de/kb0/CRU3703HG0000R01.htm] the document on the Toshiba page and there I see this 2nd HARD drive Bay is not available

    (> 3) all three (P70, L70, S70 series) come with the same TFT panels?
    See point 1). Different P70, L70, S70 models were equipped with different material parts.

    (> 4) of the series above, which takes in charge mSata?
    As far as I know that some P70 models are equipped with an mSATA SSD of 256 GB.

    (> 5) do all the model of each series are delivered with support mSata? For example, it could be that L70 - a - 13 m supports mSata is not the case of the L70-a-146?
    See point 4) not all models supports the same hardware specifications

    (> 6) all of the above, come with a S - ATA II or III S - ATA interface?
    I don t think that SATA III is supported. I guess it would be SATA II

    (> 7) which is the best of these series listed? I'm trying to understand what makes the big difference of S70 to P70 except for the envelope for example.
    Not easy to answer because there are too many models released in Europea.
    And not all models are available in each country. So I guess you will have to look for the models that have been released in your country.

Maybe you are looking for
