Lenovo Zhaoyang E49AL is divided into a zone, and the boot card is stuck in the logo interface 5

When did you buy the computer, I didn't have a warranty ** after-sales, ask what is going on, and then follow his advice to try it.

If this is the case, you should generally consider whether it is caused by memory module or graphics card problems, it is recommended to punch in the back cover of the notebook, and then unplug the memory module and the graphics card, and then use the eraser to erase the gold finger, and then plug it in to see, if not, consider replacing the memory module to see.

It's the alarm sound that the memory self-test has not passed, remove the back cover and unplug the memory, remove the oxide layer at the position of the gold finger, and install it back, if you haven't done it yourself, find a professional person to help you get it, avoid breaking it, I hope it can help you.

This alarm is a memory or graphics card failure alarm. If you can disassemble the laptop shell and make simple repairs, you can unplug the memory and wipe it and plug it in, and unplug the graphics card and wipe it and plug it in. If you don't know how to disassemble the machine, send it to a repair shop to deal with it.

Absolutely!

It is recommended that a treasure search Hynix, Micron DDR3 1600

It is cheap and can guarantee that there are basically no fakes. Unlike Samsung Kingston, there are too many fakes and licensed goods are too expensive.

Welcome to ask for satisfaction!

It's just a card slot, pretending to be a fart.

1. The memory only needs to look for those big brands.

2, suitable for change, but not much necessary, 32-bit system can also recognize more than 3 GB memory, you can use ramdisk to create a cache disk to use, and then put the cache or something on it, which is not wasted and improves the performance of the machine.

3,Win7The compatibility is very good,And whether it's 32 or 64 bits,Microsoft's 64-bit system is compatible with 32-bit programs,Don't listen to his。 Some of the most ancient software may not work, but we still have virtual machines!!

4, your needs are too simple, there is no need to change the system, otherwise you will lose more than you gain (be sure to keep the original system, if there is a problem, you can also restore it with one click, do not ask for someone to reinstall it yourself may destroy the one-click recovery, but also to solve various problems such as the driver and so on, don't you think it is troublesome).

You can add memory, which will have a certain effect.

1. The memory module is a computer component that the CPU can address through the bus and perform read and write operations;

2. Performance indicators of memory: (1) storage capacity; (2) access speed (storage period); (3) Reliability of memory; (4) Performance ratio;

3. The role of memory: memory is an indispensable part of computers (PCs, microcontrollers). Unlike dispensable external memory, memory is a component that reads and writes on a bus; Memory is more than just a data warehouse;

4. Memory classification: Memory is divided into DRAM and ROM, the former is also called dynamic random access, one of its main features is that data will be lost after power failure, we usually refer to this kind of memory; The latter is also called read-only memory, we usually start the BIOS program stored in the ROM on the motherboard first, and then it calls the Windows in the hard disk, one of the main features of the ROM is that the data will not be lost after power failure.

Hello, you can install a 64-bit system, you can choose it according to your needs.

Take care to back up important data before installing the system.

Entry-level office, **cheap, office sufficient. Selling computers is right. Now many programs are 32-bit, 64-bit, there will be compatibility problems...

Dear Lenovo users, hello!

Workaround for bootmgr is missing:

Initiation management is missing ......

It is recommended to deal with it as follows:

If boot manager bootmgr in the root directory of the C drive is corrupted or missing, the system will prompt that the operating system cannot be found when you start the computer, which is similar to the NTLDR file loss of Windows 2000 XP.

In Windows 2000 XP, to solve this kind of failure, you first need to know that the cause of the failure is the loss of the boot manager, and then go to the failure recovery console, and use the expand command in the command prompt to extract the copy of the ntldr file in the installation disc to the root directory of the C drive.

In Windows Vista it is very simple, we don't need to know exactly what is causing the system not to boot, just follow this method:

1) First of all, make use of the Windows Vista Reject Strike Series 1 - Sesame Open Door method to introduce the method by using the Windows Vista installation disc to boot the system into "System Recovery Options" and click "Startup Repair" on it.

2) The system looks for the causes that may cause the startup failure in the set order. In the background of the system, the boot recovery checker automatically tests and analyzes Windows updates (which may also lead to boot failures if the patch installation fails), system disks, disk errors, disk metadata, target operating systems, boot logs, and other contents.

3) If the system finds the cause of the boot failure and repairs it, it will enter a dialog box indicating that it has been found and tried to fix the problem.

4) Windows Vista will not display the fault cause found by default, just click the "Finish" button to restart the computer to complete the recovery operation.

If you need to see the cause of the failure, you can click Click here for more information on diagnostics and repairs on the dialog box. On the dialog box that opens, we can see that the root cause found is that the Startup Manager is missing and that the required file repair tool has been completed successfully.

Hello, under the default state of the system, the trackpad is to be turned on and turned on, and you need to turn it off by yourself, so please forgive me for the inconvenience caused.

win10 Lenovo notebook:

Start in the bottom left corner - > Settings - > devices - > select Trackpad on the left side - > remove the check to keep the touchpad on when the mouse is connected - > solved!

There should be a hard switch, on the side of the notebook. E46 e47 has, e49 should have.
