The Dell Inspiron series of laptop computers was introduced in 2000 as a consumer oriented line, available to the general public through electronics and department stores (and now Dell's website), contrasting to the business/enterprise-oriented Dell Latitude series of laptop computers, and are usually ordered from Dell directly via the website, phone, or mail-order.
Inspiron 17000 2-in-1

Inspiron 17000 2-in-is a 2-in-notebook with a 13-inch touchscreen and Intel processors. It competes with Acer Aspire R 14, Asus Transformer Book Flip TP300, HP Pavilion 1x360, Lenovo Yoga 14, Samsung Notebook spin (13-inch), Toshiba Satellite Radius 1and 14.
Power supply issues
Most Dell laptop computers have a special external power supply (PSU) which cannot be replaced by a third-party universal supply. The PSU has what's called UniqueWareâ„¢ Add-Only Memory, known under type DS250It is a parasitic power circuit memory chip connected to the center identification pin in the plug, via a 2m long unshielded wire alongside the PSU cable. This chip produces a special signal using a wire communication protocol known as "1-wire" in identifying the PSU as an original Dell PSU. This chip handles all the data needed to authenticate a charge. If a power supply not made by Dell is used, or the cable near the connector becomes damaged as is not infrequent after some use, the PSU stops charging the battery and the CPU runs slower, although the computer can be used indefinitely so long as it remains plugged in. https://swanbest.com/best-quad-core-laptop - If this problem is present at startup, the message "The AC power adapter type cannot be determined. Your system will operate slower and the battery will not charge" is displayed. This will continue until the external PSU is replaced. A few third-party suppliers make power supplies with specific provision for Dell computers at lower prices than Dell's. It is possible to work round the slowdown, but not the battery charging, by installing a CPU clock utility.
On some models (the 9100 for instance), the problem can be worked around by starting the computer without a battery installed and fitting the battery after the computer has booted.
Another problem arises after much use with the motherboard power connector; flap-like metal parts which contact the outside of the plug lose their tension and fail to make contact so that power does not reach the computer. The "official" solution is to replace the connector on the motherboard, which requires partial dis-assembly of the computer and desoldering a part with several pins; many companies charge a considerable sum for the work involved. Various simple alternatives have been suggested; for example a thin "skin" of solder on the outside of the barrel of the connector on the PSU (with care not to overheat the connector's plastic parts; and this thickened connector should not be used with other, not faulty Dell laptops, as it will stretch the springs and damage or even overheat the plug and socket assembly, causing them to melt or bond permanently).

One other problem can happen with the wattage rating of the power supply. There are Dell power supplies that were used for different Inspiron models which have the same plug assembly and voltage, a 6watt supply model PA-and a 90 watt supply model PA-Some models (for example the Inspiron 1100) shipped with a PA-If a PA-(or equivalent aftermarket supply) is used in these models then the system might not boot at times. In such cases, it will light the battery light for a few seconds when the supply is plugged in. This can also happen if the power supply becomes marginal. Marginal supplies can show as supplying full voltage even if tested with a volt meter while the supply is plugged into the computer and an attempt is made to turn on the computer.
Hibernation sensor problem
A problem exists with the hibernation sensor located in some older laptops. Unlike many laptops that use a mechanical switch to detect when the lid is closed, in these systems the sensor is a magnetic reed switch that is located between the touchpad and the front edge of the laptop. There is a magnet that is located in the top lid above this switch, and when the lid is closed the magnet triggers the reed switch. If the magnet loses strength then the system will not go into suspend or hibernation if the lid is closed. The magnet strength can be checked by running a paper clip along the top edge of the screen. A worse problem happens if the reed switch fails. Sometimes the switches will fail in a closed position with the contacts sticking together. In that case the system will not switch on. There are several ways to check for this. First the laptop can be partially disassembled and the mouse assembly can be unplugged from the system board and the system switched on. If the system boots with the mouse unplugged then it is the switch. Another way to check for the problem is by running a magnet over the reed switch, there should be a faint click when the magnet triggers the switch. This does not require disassembly but the magnet must be in the correct position and be strong enough. Some people have modified the circuitry of the laptop by cutting the switch off of the assembly, with the downside being the system will no longer suspend if the lid is closed.
Some 17" Inspiron 8600, 9200, 9300, 6000, 1750, and XPS Gen notebook LCDs have a vertical line manufacturing defect. Symptoms range from individual lines to entire bars of the screen with inverted colors.

Tangled up in blue. The HP Notebook 15z is a run-of-the-mill, 15.6-inch notebook designed to fulfill basic needs. While it fails to stand out from the crowd, it offers "just enough" performance for everyday tasks and has no real significant shortcomings aside from a fairly high price..
